    [0001] The invention relates to the field of fuel filling systems of a vehicle tank, and more particularly to liquid vapor separation devices arranged on the filling head placed at the inlet of the tank. tubing leading to the fuel tank. The liquid vapor separation devices are known from the state of the art. They are connected on the one hand to the fuel vapor evacuation device disposed in the tank, and on the other hand to a vapor filtration system through which the vapors are treated before being returned to the atmosphere. Their function is to extract the droplets and condensates present in the vapors escaping from the tank, so as to avoid overloading the vapor treatment system. The separation device thus comprises separation means and drainage means for returning to the tank the liquid elements trapped in the separator.
    [0002] These devices can be installed on the fuel tank as proposed in US 6,405,747, or directly on the filler head as proposed in US 2008/018972. This second form of assembly makes it possible, among other advantages, to recover the condensates as far downstream as possible from the pipe leading the vapors from the tank to the filtration device.
    [0003] A liquid vapor separator is generally in the form of a hollow body in which are arranged fixed walls, oriented vertically, and forming a labyrinth through which the vapors circulate. The fuel droplets are retained by the walls of the labyrinth on which they flow by gravity and are recovered in the drainage means. The drainage means are connected to the fuel tank by a conduit or, preferably, open directly into the receiving duct of the filling head. When the vehicle is traveling, the droplets extracted from the vapors from the tank are discharged directly into the filling head, and return to the tank through the filler neck. The vapors also have the possibility of returning to the filling head via the drainage duct, which makes it possible to balance the pressures in the circuit. Since the filling head is closed by the tank cap of the vehicle, the vapors can not escape to the outside through this channel. In contrast, when filling the tank, the vapor flow increases, and a portion of this flow can then escape to the atmosphere by the filling head which is in the open position. Also, there is provided a device for isolating the drainage means of the filling head during this operation. This device may be in the form of a valve which closes the passage between the drainage means and the filling head, and which is actuated by the movement of introduction of a cannula into the filling head. It is observed, however, that when the filling flow, and consequently the flow of steam, are intense, the filling operation is disturbed by the premature closing of the filling gun. These disturbances are caused by excessive overpressure in the fuel tank.
    [0004] The object of the invention is to provide an original solution to this drawback. The liquid vapor separator according to the invention comprises an inlet duct, opening into a hollow body communicating on the one hand with drainage means and on the other hand with an outlet duct. Said hollow body contains separation means for directing a stream of vapors from the inlet duct to the outlet duct, and extracting droplets present in the vapor stream so that they flow into said drainage means, said liquid vapor separator is characterized in that the separation means can take a first and a second configuration, arranged so that the pressure drop experienced by the flow of vapors flowing in the hollow body between the duct the inlet and the outlet duct when the separation means are in the second configuration, is strictly less than that undergone by the same vapor flow when the separation means are in the first configuration. Thus, when the reservoir is in the filling condition, the separation means are placed in the second configuration, so that the pressure drop between the inlet duct and the outlet duct is substantially reduced. Because of this reduced pressure drop compared to the first configuration, the vapor flow no longer passes through the labyrinth of walls used to trap the droplets, and passes directly from the inlet duct to the outlet duct towards the filtered. The flow of the steam flow is facilitated all that, which reduces the overpressure in the tank and prevent premature closures of the gun. The separation means are returned to the first position when the filling operation is completed. The invention may also have multiple embodiments, the characteristics of which, taken individually or in combination, are the following: the separation means comprise at least one wall movable in rotation about an axis, so that in said first configuration, the movable wall is placed in a first angular position, so as to form, with internal walls of the hollow body, a labyrinth in which the vapors coming from the inlet duct are forced to circulate, in said second configuration, the movable wall is placed in a second angular position, separate from the first angular position, so as to let the vapors directly from the inlet duct to the outlet duct. - The wall is movable about a substantially vertical axis. - The hollow body has the general shape of a cylinder, of the same axis as the axis of rotation of the movable wall, and having an inner diameter substantially equal to a width of said movable walls. The separator comprises two movable walls, arranged so that, when they are placed in said second angular position, sections of the intersection of the inlet duct and the outlet duct with the hollow body are included in a space situated between the two moving walls. - A horizontal insulation partition, connecting the two walls together, is arranged vertically below said sections, so that when the movable walls are placed in the second angular position, the space included and located above the insulation wall between the two movable walls and located between the inlet duct and the outlet duct is isolated from the drainage means. - The separation means comprise one or more walls movable in rotation about a substantially horizontal axis. - In said first angular position the movable wall is disposed substantially vertically in the hollow body, and in said second angular position, the movable wall is arranged so that the hollow body, the inlet duct and the outlet duct are isolated from the drainage means. The hollow body has a substantially cylindrical or hemispherical shape, and the wall pivots about an axis located in an equatorial plane of the hollow body, and has a shape similar to an inner equatorial section of said hollow body and the section of the passage between the hollow body. hollow body and drainage means. The invention also relates to a filling head of a fuel tank, comprising a receiving duct intended to receive a cannula, characterized in that it comprises a vapor liquid separator according to one of the preceding characteristics. The above filling head can also have multiple embodiments, the characteristics of which, taken separately or in combination, are the following: a movable valve is provided between an open position leaving the passage between the means free; drainage and the receiving duct of the filling head when the separation means are in the first configuration, and a closed position closing the passage between the drainage means and the receiving duct of the filling head when the separation means are in the second configuration. - The drainage means of the vapor liquid separator open directly into the receiving duct. - Means are provided to activate the passage of the liquid vapor separator from the first configuration to the second configuration under the action of introduction of the cannula into the receiving duct of the filling head. The vapor liquid separator comprises elastic means for generating the passage of the vapor liquid separator from the second configuration to the first configuration, when the cannula is withdrawn from the receiving conduit of the filling head. Finally, the invention is concerned with a method of filling a fuel tank comprising a filling head according to one of the features described above, in which the inlet duct of the vapor liquid separator is connected to the tank. of fuel, and the outlet pipe of the liquid vapor separator is connected to means for treating fuel vapors, characterized in that it comprises the steps in which: - the separation means are placed in the second configuration by introducing a cannula in the conduit for receiving the filling head, so that the vapors from the tank pass directly to the steam treatment means during the filling phase, the separation means are replaced in the first configuration by removing the cannula of the filling head duct, so that the vapors from the tank pass through said separation means before go towards the means of treatment of the vapors. The invention will be better understood on reading the appended figures, which are provided by way of example and are not limiting in nature, in which: FIG. 1 represents a schematic view of a vehicle tank comprising a filler pipe of which the head is equipped with a liquid vapor separator.

    [0005] FIG. 1 schematically illustrates a vehicle tank 4, connected by a filling pipe 41 to a filling head 2. The inlet 201 of the filling head is adapted to allow the introduction of a filling cannula 3 The tank is equipped with monitoring and safety devices 40 whose functions need not be specified in the present description. The fuel vapors are conducted through a vapor vent pipe 43 from a degassing unit 42 to vapor treatment means such as a hydrocarbon vapor absorber filter 44 (canister) for the treatment of vapors. hydrocarbons before their reinjection into the engine of the vehicle. The fuel vapors from the tank are loaded with droplets that can reduce the performance of the canister 44. To avoid this, it is planned to place on the vapor vent pipe 43 a liquid vapor separator 1, to trap the droplets of fuel, so as to let only the vapors in the direction of the canister 44. The fuel droplets are then reinjected into the tank via the filler neck 41.
    [0006] The vapor liquid separator 1 is generally arranged at the level of the filling head 2, as far as possible downstream of the pipe 43 for evacuation of the vapors, where it is also convenient to collect the liquid elements for the to the tank, but it can also be installed at any point of this tubing 43. As will be seen in detail later, the liquid vapor separator comprises at least one wall 130 placed across the vapor flow up the tank on which are deposited the fuel droplets which then fall by gravity into the filler neck 41. The fuel vapors bypass the wall 130, in the direction of the arrows, before moving towards the canister 44. This additional route imposed on the vapor, like a labyrinth, is the source of an additional pressure drop in the vapor evacuation pipe 43, the effects of which can go up squ'au reservoir 4 where we observe, under certain conditions, a slight overpressure. In the current operating mode, the inlet 201 of the filling head is closed. The flow of vapor up through the vapor evacuation pipe 43 is very small, and the pressures inside the tank 4, the filling pipe 41 and the vapor evacuation pipe 43 are substantially balanced by via the connection between the filling head and the vapor liquid separator. During the filling phase of the reservoir, a cannula 3 is introduced into the inlet 201 of the filling head, and the fuel flows inside the filler neck 41. The flow of vapor up through the tubing Vapor discharge 43 then strongly increases, and can escape to the atmosphere through the inlet of the filling head 201 which is wide open. To avoid this, it is planned to close the passage between the liquid vapor separator and the tank head with a valve 210 whose closure is caused by the introduction of the cannula 3. The vapors back then through the vapor evacuation pipe 43 is then forced to circulate through the labyrinth formed by the wall 130. The pressure drop imposed by the wall 130 then rises significantly and creates an excess pressure of a few mb in the tank 4 This overpressure then rises in the filler neck 41 and may, in certain circumstances, activate the safety devices placed in the cannula to prevent the phenomena of discharge, and cause the stop filling.
    [0007] Figures 2 to 11 show several embodiments of the invention whose object is to reduce this disturbance. In each of these variants, the organs providing the same functions are identified by the same numerical indices. According to a first embodiment of the invention, FIG. 2 shows a filling head 2 equipped on its upper part with a liquid vapor separator 1a. The filling head comprises a receiving duct 200 whose inlet 201 is adapted to receive a cannula (not shown) and whose outlet 202 is connected to the filling pipe 41 leading to the reservoir. FIG. 2 illustrates the case in which the walls 130 are placed in the first configuration, that is to say when the filling head is placed in the running configuration of the vehicle engine, in which the entry of the head filling 201 is closed by the tank cap (not shown). The vapor liquid separator comprises an inlet conduit 110 connected to the vapor discharge pipe 43 (not shown) from the reservoir. This inlet duct 110 opens into a hollow body 120 in which are disposed the separation means formed by at least one wall and, in the case that is the subject of the present description of two walls 130 placed substantially vertically. The hollow body 120 is connected to an outlet duct 111 through which the vapors escape in the direction of the canister. The walls 130 extend into drainage means 123 opening directly into the receiving duct 200. The walls 130 are held together by an upper plate 131 disposed under the upper wall 122 of the hollow body 120, and are rotatable around of an axis XX '. In this first configuration, the walls are oriented so as to form an obstacle and force the flow of steam from the inlet duct 110 to bypass said walls 130 to evacuate to the outlet duct 111, as represented by the dashed arrows. In the case that is the subject of this description, the walls are disposed substantially perpendicular to the axis ZZ 'of the ducts 110 and 111, as shown in Figure 3, which is a top view according to the section AA of the assembly formed by the liquid vapor separator la and the filling head 2. Advantageously, the hollow body 120 and the drainage means 123 have a substantially cylindrical shape so that, by adjusting the width of the walls 130 to the inside diameter said cylinder, the vapors from the inlet duct 110 have no other possible passage to go to the outlet conduit 111 than to circumvent them from below. In this way, the fuel droplets contained in the vapors are deposited on the walls 130 and on the inside of the wall 121 of the drainage means 123, and flow by gravity towards the receiving duct 200. The walls 130 are also secured to a lower plate 132, in which openings are provided to allow free circulation of vapors and droplets between the drainage means 123 and the receiving duct 200. The filling head, according to this first embodiment of the invention. invention has a valve 210, mounted on a hinge 211 of substantially horizontal axis, for closing the passage between the drainage means 123 and the receiving duct 200. The valve 210 comprises at its end a cam 213 for to collaborate with a helical ramp 133 arranged in the lower plate 132. An elastic blade 212, intended to collaborate with an elastic lever 214 , is disposed under the valve 210.
    [0008] The elastic lever 214, mounted on a plate 216, via a hinge 217 of horizontal axis, substantially parallel to the axis of the hinge 211 of the valve 210, has at its end a pallet 215. The pallet 215 and the elastic lever 214 can usefully be electrically connected to ground. The passage from the first configuration to the second configuration is under the action of the introduction of a cannula 3 in the inlet 201 of the filling head when the vehicle is refueled. The head of the cannula comes into contact with the pallet 215 and pushes it by rotating the elastic lever 214 around its hinge 217. In its movement, the elastic lever 214 drives the blade 212 and pivots the valve 210 around the hinge 210. its axis 211. The cam 213 enters the helical ramp 133, and drives the lower plate 132, and the walls 130 which are integral with it, in rotation around the axis 0 (') when the valve 210 is in position. closed position, the walls 130 have rotated about 900 to be in the second configuration, as shown in Figure 4 and Figure 5. The walls 130 are then substantially parallel to the axis ZZ 'of conduits 110 and 111. It will be noted here that the embodiments which are the subject of the present description show inlet and outlet channels 110 and 111 whose axes are aligned with an axis ZZ ', but that it is possible to arrange the respective positions of s inlet and outlet conduits of the hollow body in different ways and equivalent by the adaptation of adjacent bodies. The electrical continuity between the cannula and the vehicle is provided by the pallet 215 and the elastic lever 214. In this second configuration, the vapor flow, important during the filling phase of the tank, no longer meets the obstacle formed by the walls. 130, and can go directly from the inlet duct 110 to the outlet duct 111 as illustrated by the dashed arrow. And even if the passage under the bottom plate 132 remains open, the direct flow between the inlet ducts 110 and outlet 111 represents a lower pressure loss and allows the vapors to be directed to the canister during the filling phase without causing overpressure in the tank. Closing the valve 210 also prevents vapors from escaping into the atmosphere through the inlet of the filling head 201. It will be appreciated that when the separating means is in the second configuration, the fuel droplets present in the flow of vapor entering via the duct 110 pass directly to the outlet duct 111 and to the canister 44 because of the less effective extraction function operated by the vapor liquid separator 1 during the filling phase of the tank. The percentage of droplets extracted from the vapor stream when the separation means are in the second configuration is therefore much smaller than the percentage of droplets extracted, for an identical vapor flow, when the separation means are placed in the first configuration.
    [0009] At the removal of the cannula, a helical return spring 114 housed in the space between the upper plate 131 and the upper wall 122 of the hollow body 120 brings the walls 130 into the first configuration illustrated in FIGS. 2 and 3. The figures 6 to 9 illustrate a second embodiment of the invention. In this variant, the filling head no longer includes a valve closing the passage between the drainage means 123 and the receiving duct 200. Similarly, the walls 130a and 130b are no longer connected by a lower plate. In the same way as in the first embodiment of the invention, the walls 130a and 130b are adjusted to have a width substantially equal to the inside diameter of the hollow body 120 of cylindrical shape, as well as drainage means 123.
    [0010] When the liquid vapor separator lb is disposed in the first configuration, illustrated by FIGS. 6 and 7, the walls 130a and 130b are placed substantially perpendicular to the axis ZZ 'of the inlet and outlet ducts 110 and 111, and form an obstacle forcing the flow of vapors from the inlet duct 110 to circumvent them (see the dashed arrows), so that the droplets present in the vapors flow by gravity in the drainage means 123 towards the duct The rotational movement of the walls 130a and 130b around the vertical axis 0 'to move from the first configuration to the second configuration is achieved by a mechanism 115 housed between the upper plate 131 and the upper wall 122. The mechanism is rotated by a flap 219 disposed at the end of an eccentric shaft 218 of vertical axis parallel to the axis 0 (flap 219 is suitably placed on the path of the head of the cannula, so that the introduction of the latter into the receiving conduit 200 causes the rotation of the flap 219 and the off-center shaft 218, and the rotation of the upper plate supporting the walls 130a and 130b through the mechanism 115. The shaft 218 is off-center so as not to come into contact with the head of the cannula. FIGS. 8 and 9 show the filling head 2 and the vapor liquid separator 1b according to this second embodiment of the invention in the second configuration, in which a filling cannula 3 is introduced into the inlet 201. Under the action of the movement of the flap 219, the walls 130a and 130b have rotated about 90 ° around the axis 0 ('and are now oriented in a direction substantially parallel to the axis ZZ' of the ducts 110 and 111. In reference now to FIG. 9, in which the vapor liquid separator 1b is placed in the second configuration, it is observed that the inlet and outlet ducts 110 and 111 are arranged so that that the section of their intersections, respectively 112 and 113, with the wall 122 of the hollow body 120 are included in the space separating the two walls 130a and 130b, so that when the walls are in the second configuration, the vapors are t of the tank through the inlet duct 110 are forced to flow between the two walls 130a and 130b to reach the outlet duct 111. An isolation wall 134, arranged vertically below the inlet sections 112 and 113, connects the two walls 130a and 130b together, and avoids the passage of vapors to the receiving duct 200 during the filling phase when the walls 130a and 130b are arranged in the second configuration. Thus, when the vapor liquid separator 1 is in the second configuration, and similarly to the first embodiment of the invention, the vapors pass directly from the inlet conduit 110 to the outlet conduit 111, with a loss of reduced load to prevent overpressure in the fuel tank. When the cannula 3 is withdrawn from the filling duct 200, the pallet 217 is released, and a helical return spring 114, disposed in the space between the upper plate 131 and the upper wall 122 of the hollow body 120, causes the walls 130a and 130b, as well as the pallet 217, from the second configuration to the first configuration. Figures 10 and 11 illustrate a third embodiment of the invention wherein the liquid vapor separator 1c comprises a wall 135 pivoting about a hinge 136 of horizontal axis YY '. This axis YY 'is disposed, in the context of the example forming the subject of the present description, substantially perpendicular to the axis ZZ' of the ducts 110 and 111. When the separator 1c is placed in the first configuration, as shown in FIG. 10, the wall 135 obstructs the passage between the inlet duct 110 and the outlet duct 111, forcing the fuel vapors to bypass it to move towards the canister, as illustrated by the Dotted arrows in FIG. 10. The fuel droplets then flow by gravity along the wall 135 towards the receiving duct 200. The wall 135 supports an extension 137, extended by an elastic blade 138. The articulation 136 is disposed vertically below the section of the intersection of the ducts 110 and 111 with the wall 121 of the hollow body 120, so that the rotation of the wall 135 around the axis YY 'closes the passage between the body creu x 120 and the drainage means 123, and places the wall 135 in the second configuration as shown in Figure 11. In this second configuration, in the tank filling phase, the vapors from the inlet duct 110 pass directly to the outlet duct 111 and through the separator 1c with a reduced pressure drop so as not to create overpressure in the tank. Vapors also can not return to the receiving duct 200. It will be observed at this stage that it would be entirely possible to install in the separators according to the second (1 b) and the third (1c) embodiment. of the invention a valve 120 disposed between the drainage means 123 and the receiving duct 200, of the type provided in the separator (1a) according to the first embodiment of the invention. This addition, however, does not seem necessary insofar as the walls 130a, 130b or 135 provide a simple and economical way the separation function between the gas flow path and the receiving duct 200 during the filling phase, thus allowing avoid their escape into the atmosphere.
    [0011] During the introduction of the cannula 3, the head of the cannula 3 pushes the pallet 215 and tilts the elastic lever 214 around its hinge 217 so that the pallet 215 engages the elastic lever 138 located in the extension of the extension 137, and causes the wall 135 to rotate about the axis YY '. The drainage means 123 located between the hollow body and the receiving duct 200 have a reduced height so as to allow the elastic lever 138 to collaborate simply with the pallet 215, so that the lower part of the wall 135 partly dips into the duct 200 when the wall 135 is placed in the first configuration. In this third embodiment of the invention, the hollow body then takes the general shape of a cylinder axis YY ', or a half-sphere whose diameter passes through the axis YY' of the articulation 136. The axis YY 'is therefore located in an equatorial plane of said hollow body. And the wall 135 takes respectively a rectangular or circular shape similar to an equatorial section inside said hollow body. The shape of the section of the passage between the hollow body 120 and the drainage means 123 is then similar to the shape of the wall, so as to obtain a tight closure when the wall 135 is in the second configuration. A spring (not visible) placed around the hinge 136 makes it possible to bring the wall 135 of the second configuration back to the first configuration when the cannula 3 is withdrawn from the receiving duct 200. The method of filling a reservoir according to the invention then comprises the steps in which: - the separation means are placed in the second configuration by introducing a cannula into the receiving duct of the filling head, so that the vapors from the tank pass directly to the means for treating the vapors during the filling phase and, - replacing the separation means in the first configuration by removing the cannula from the conduit of the filling head, so that the vapors from the tank pass through said means of separation before to go to said vapor treatment means. The three embodiments of the invention forming the basis of the present description are not limiting, provided that they make it possible to obtain the effects as described and claimed. -13- NOMENCLATURE OF DIGITAL INDICES USED 1, 1a, 1b, 1c Separator Liquid Steam 110 Inlet duct 111 Exit duct 112 Section of the intersection of the inlet duct with the wall of the hollow body 113 Section of the intersection of the outlet duct with the wall of the hollow body 114 return spring 115 mechanism for rotating the upper plate 120 hollow body 121 walls of the drainage means 122 walls of the hollow body 123 drainage means 130 means of separation; Wall moving about a vertical axis of rotation () 0 (') 130a, 130b Means of separation; Movable walls around a vertical axis of rotation () 0 (') 131 Top plate 132 Bottom plate 133 Spiral ramp 134 Insulation wall 135 Means of separation; Movable wall around a horizontal axis of rotation (YY ') 136 Articulation of the movable wall of horizontal axis (YY') 137 Extension 138 Elastic blade of the extension 2 Filling head of the fuel tank 200 Intake duct 201 Filling head inlet 202 Filling head outlet 210 Check valve 211 Valve joint 210 212 Elastic blade of the valve 213 Came 214 Elastic lever 215 Pallet 216 Platen 217 Elastic lever articulation 218 Offset shaft -14- 219 Flap 3 Cannula fuel filling 4 Fuel tank 40 Fuel tank instrumentation 41 Fuel filling pipe 42 Degasser 43 Fuel vapor vent pipe 44 Means for treating vapors; Canister10
