    DETAILED EXHIBITION OF THE INVENTION
    Figure 1 shows a perspective view of an embodiment of an arrangement 300 according to the invention of a gas valve 200 adapted to a gas burner 100. And Figure 2 shows a second perspective view of the arrangement 300 of Figure one.
    25 The arrangement 300 shown is adapted to a gas burner 100. The gas valve 200 is a thermoelectric safety valve comprising a valve body 10, an inlet conduit 11 of the gas from a gas supply source (not shown in the figures), and two outlet ducts 12, 13 of the gas that are adapted to drive the gas towards the gas burner 100. The gas valve 200 comprises inside a
    30 valve body cavity 10 a rotating regulator element 90, allowing the regulator element 90 to regulate the flow of incoming gas from the inlet duct 11, to the outlet ducts 12, 13 depending on its angular position. The gas valve 200 also comprises a rotary shaft 20 coupled to the regulator element 90 and which


    protrudes from the valve body 10 outwards. The axis 20 allows the regulating element 90 to rotate between an initial turning position and a final turning position, allowing this range of operation to regulate the gas flow from an OFF position without gas flow, to a position of minimum gas flow, passing through a maximum flow position and intermediate gas flow positions, in this embodiment of the gas valve 200.
    The gas valve 200 also comprises a flat cover 16 that closes the valve body 10 by means of screws, said cover 16 leaving the axis 20. The cover 16 is externally connected with a pulsating plate 17, a switch 18 being of a spark generator for the gas burner 100, coupled to the cover 16. The pulse plate 17 comprises an end 17a that protrudes in the same plane of the pulse plate 17, and an end 17b that protrudes perpendicularly to the plane of the plate push button 17 in the direction of the cover 16. The push plate 17 is mounted on the shaft 20 through a through hole, The push plate 17 comprises a circular notch that fits into a shaft in the passage hole of the shaft 20 circular groove of the axis 20, so that the pulsating cover 17 is attached to the axis 20 without the need for circlips or screws. When the axis 20 is pressed and the pulse plate 17 is dragged to actuate the switch 18 with the end 17a, the return to its point of origin is carried out by means of an internal spring disposed inside the axis 20 (not shown in the figures ).
    The cover 16 has a projection at 90 ° at a lateral end to which the switch 18 is attached externally, by means of a single screw. The cover 16 also comprises on its internal face a projection (not shown in the figures), obtained by injection or extrusion, which makes it possible to stop the rotation of the axis 20, by abutting a projection of said axis 20 with the projection of the cover 16. The cover 16 also includes a hole 16a that passes through it, so that when the pulsation plate is mounted 17 on the axis 20, the end 17b of the pulse plate 17 is inserted into the hole 16a of the cover 16, which allows the guidance of said pulse plate 17.
    The arrangement 300 of the gas valve 200 comprises in this embodiment two outer ducts 30a, 30b which are connected at a first end, as will be described later, to a respective outlet 14, 15 of the outlet ducts 12, 13, the outer ducts 30a, 30b being fluidly communicated with the outlet ducts 12,


    13, and therefore allowing gas flow to the gas burner 100. The gas burner 100 comprises an inner burner crown 110a and an outer burner crown 110b, as well as an inner burner inlet 111a and a burner inlet. 111b outer, both burner inlets in the form of a gas injection tube, said inner burner inlet 111a and outer burner inlet 111b fluidly communicated with the inner burner crown 110a and the respective outer burner crown 110b. Each of the inner burner inlets 111a and outer burner inlet 111b comprise an inner inlet 112a and a respective outer inlet 112b that fluidly communicates with a second end, as will be described later, of the outer ducts 30a, 30b respectively.
    The arrangement 300 also comprises two gas injectors 40a, 40b connected and in fluidic communication with the respective outer conduit 30a, 30b. Each gas injector 40a, 40b is fixedly arranged inside the respective outer conduit 30a, 30b. Each gas injector 40a, 40b has a substantially cylindrical shape comprising a respective inlet 43a, 43b, and a respective outlet nozzle 41a, 41b of smaller diameter than the inlet 43a, 43b, allowing gas flow from the inlet 43a, 43b towards the outlet nozzle 41a, 41b. The gas coming from the outlet ducts 12, 13 of the gas valve 200, flows through the outer ducts 30a, 30b, passes through the gas injectors 40a, 40b, and exits through the outlet nozzles 41a, 41b to the crown of the internal burner 110a and the respective external burner crown 110b of the gas burner 100, through the internal burner inlet 111a and the respective external burner inlet 111b.
    Thus, when you want to light the gas burner 100, either one of the burner crowns 110a, 110b or both, the shaft 20 is pressed and rotated to rotate the regulating element 90 inside the valve body 10 of the gas valve 200 to a specific angular position desired by the user reaching a gas flow to the gas burner 100. Pressing the axis 20 moves the pulse plate 17, guided with the end 17b in the hole 16a of the lid 16, and the end 17a of said pulse plate 17 presses the ignition switch 18, sparking next to the gas burner 100, and generating a flame.


    Figure 3 shows a perspective view of the two outer ducts 30a, 30b of the arrangement 300 of Figure 1, with a nut 50 and an ear 60 mounted on each of said outer ducts 30a, 30b, and a support member 80 mounted between the two 5 outer ducts 30a, 30b. Figure 4 shows a perspective view of the outer duct 30a of the arrangement 300 of Figure 1. Figure 5 shows a perspective view in partial longitudinal section of the two outer ducts 30a, 30b of Figure 3, showing inside from each outer conduit 30a, 30b the respective gas injector 40a, 40b which is fixedly arranged. And Figure 6 shows a partial perspective view
    10 in detail of the two outer ducts 30a, 30b of Figure 5.
    In this embodiment of the arrangement 300 the gas injectors 40a, 40b and the outer ducts 30a, 30b are of malleable material. Thus, for example, the outer ducts 30a, 30b are made of aluminum, but can also be made of copper or an aluminum alloy 15 with bronze or other alloys. The gas injectors 40a, 40b are made of brass, but they can also be for example copper. These malleable materials, that is, that they can be given a different form than the original without breaking them, allow their deformation. Thus, the outer ducts 30a, 30b of aluminum are tubes originally of for example 1 millimeter (mm) thick, which can be given various shapes with small
    20 efforts In this way, the outer ducts 30a, 30b are made flexible allowing the connection of the gas valves and the gas burners in virtually any arrangement. If we add to this that the gas injectors 40a, 40b are arranged inside the outer ducts 30a, 30b, the mounting flexibility is almost absolute.
    25 To fix gas injectors 40a, 40b inside the outer ducts 30a, 30b, and thus avoid undesirable displacements in operation, in this embodiment of arrangement 300 both the gas injectors 40a, 40b and the outer ducts 30a, 30b deform in an area of its surface. Thus, the surfaces of the gas injectors 40a, 40b and the outer ducts 30a, 30b are deformed in an area of the contour of the
    30 surface where the gas injectors 40a, 40b are located relative to the surface contour of the outer ducts 30a, 30b, referred to as the respective deformation zone 42a, 42b and 32a, 32b.


    An area of deformation of an element is understood as the area where deformation of said element occurs. If the element comprises an outer surface and an inner surface in the deformation area, and an external force is applied to the element applied on the outer surface, which has an orthogonal direction to said outer and inner surfaces in the deformation area, it is produced a groove-shaped deformation on the outer surface, and a protrusion-shaped deformation on the inner surface.
    This deformation of the surfaces can be done by applying external forces with various transformation techniques. One technique is crimping-pressing, which consists of, after placing the pieces in their proper place, laterally applying force by means of pressing and shaped tools, to deform the surface of the materials in the deformation zone, and in this way Fix the pieces with respect to each other. In the embodiment of the arrangement 300 shown, the deformation zone 42a, 42b and 32a, 32b of the gas injectors 40a, 40b and the outer ducts 30a, 30b is a semicircular groove, viewed from the outer face, or is a projection, seen from the inner face, of said outer ducts 30a, 30b, and is a semicircular groove seen from the outer surface of said gas injectors 40a, 40b, since it is prevented from protruding as a projection on the inner surface, which contours each of the surfaces of the injectors and ducts. The projection formed on the inner surface of the outer ducts 30a, 30b fits into the groove formed on the outer surface of the gas injectors 40a, 40b, and both parts are fixed.
    In other embodiments of the arrangement 300, the fixing of the gas injectors 40a, 40b inside the outer ducts 30a, 30b is performed using for example corrugated stainless steel flexible ducts 30a, 30b. When corrugating a smooth surface it is provided with stretch marks or projections in a regular and convenient way, and in this way it is given flexibility. The fixing of the gas injectors 40a, 40b is carried out in a smooth area of the outer ducts 30a, 30b with a technique for example crimping-pressing, as explained above.
    The outer ducts 30a, 30b are flexible in at least a portion of their length, as explained above. Good because they are made up of a material totally


    Malleable as aluminum, copper or an aluminum alloy with bronze or other alloys, or being less malleable, but with corrugated areas that give it flexibility such as stainless steel. The gas injectors 40a, 40b are arranged in a straight section 33a, 33b respectively of the outer ducts 30a, 30b to facilitate their location inside said outer ducts 30a, 30b, and to perform the crimping-pressing operation, being the deformation zone 32a, 32b of the outer ducts 30a, 30b in the straight section 33a, 33b.
    In this way there is great flexibility in adapting the arrangements 300 to the gas burners 100 that can be arranged in a gas cooking apparatus. As well as state-of-the-art provisions have rigid outer ducts, thereby hindering the assembly of said arrangements in different configurations of gas cooking appliances, the flexibility of outer ducts 30a, 30b of arrangement 300 of the invention, as well as having the injectors 40a, 40b inside said outer ducts 30a, 30b, allows the arrangements 300 to be arranged in virtually any position in a gas cooking apparatus.
    The arrangement 300 comprises in this embodiment a nut 50 incorporated in each of the outer ducts 30a, 30b, allowing said nut 50 to join each of the outer ducts 30a, 30b with the outlet ducts 12, 13 of the gas valve 200 To this end, the outlets 14, 15 of the outlet ducts 12, 13 comprise a threaded area, and the outer ducts 30a, 30b each comprise at its first end 31a, 31b each a flared mouth, said flare mouth having a perimeter fin . The fin of the mouth of each first end 31a, 31b rests on the end of the threaded area of the outlets 14, 15 of the outlet ducts 12, 13, and then the nut 50 is threaded into said threaded area. This type of connection allows even greater flexibility, as it allows the external ducts 30a, 30b to be shaped and subsequently incorporated into the valve body 10 of the gas valve 200, the same valve body 10 being able to be defined for different cooking devices of gas, varying the outer conductors 30a, 30b.
    The arrangement 300 is adapted to operate with gaseous fuels of various types, in particular GN natural gas or LPG liquefied gas. For this and in the first place it is necessary


    adapt the gas injectors 40a, 40b to the required gas, since the outlet nozzle 41a, 41b of said gas injectors 40a, 40b is of different diameter according to the gas supplied, larger diameter for natural gas GN than for liquefied gas LPG On the other hand, and to perform a correct combustion in the gas burner 100, it is necessary that the supplied gas be mixed with a correct amount of air and in a homogeneous manner. For this, two zones are defined, one zone for each of the gaseous supply fuels, natural gas GN or LPG liquefied gas, in which a mixture of gas and air is produced. One area, for LPG liquefied gas, is the interior of the outer ducts 30a, 30b, in an area that is just after the outlet nozzles 41a, 41b of the gas injectors 40a, 40b in the direction of the gas flow . For this, each of the outer ducts 30a, 30b comprises at least one air inlet hole 34 inside the said outer ducts 30a, 30b. In this embodiment of the arrangement 300, the outer ducts 30a, 30b each comprise four air inlet holes 34 arranged symmetrically every 90 °.
    For LPG liquefied gas, the existence of air inlet is necessary next to the gas injectors 40a, 40b, called primary air, and this primary air is not necessary if the supply is of natural gas GN, provided there is a second zone of mixture of air at the entrance of the gas burner 100, the air of this second zone being the so-called secondary air, prior to the arrival of the mixture of air and gas to the gas burner 100. In the LPG liquefied gas, the orifices of Air inlet 34 may be partially covered by the end of the gas injectors 40a, 40b as shown in Figures 5 and 6, but they may also be completely free, always according to the combustion needs of the gas burners 100.
    A second end 35a, 35b of the outer ducts 30a, 30b comprises a flared mouth 36 comprising a perimeter fin 37. The arrangement 300 comprises in this embodiment two ears 60, each of which comprises a metal plate 62 with a specific cut-out shape. Each ear 60 comprises an adjustment mouth 61, which is a hole in the plate 62, which is arranged in the plate 62. In this embodiment of the arrangement 300, the adjustment mouth 61 is formed by piercing and embedding the plate 62, of such that said adjustment mouth 61 comprises a fin that protrudes substantially orthogonally from the plate 62. Thus, when an ear 60 is mounted on each


    of the second ends 35a, 35b of the outer ducts 30a, 30b, the adjustment mouth 61 is adjusted to the outer contour of the outer duct 30a, 30b respectively against the fin 37 of the mouth 36 of the second end 35a, 35b of the outer ducts 30a, 30b. This adjustment is made so that the ear 60 can rotate around the outer conduit 30a, 30b.
    The ear 60 also comprises a gripping element 63, which is a small plate protruding from the plate 62. When the arrangement 300 is mounted with the gas burner 100, each of the plates 62 of each ear 60 is coupled to the Inlet port 112a inside and the respective outside inlet 112b of the inner burner inlet 111a and outer burner inlet 111b. The inlet nozzles 112a, 112b comprise passages (not shown in the figures) that allow secondary air to pass inside the burner inlets 111a, 111b, depending on the angular position of each plate 62 of the ears
    60. In this way, by rotating the plate 62 by means of the gripping element 63, the amount of incoming secondary air can be varied, and as the mouth 36 of the second end 35a, 35b of the outer ducts 30a, 30b is disposed open in the plate 62, allows the gas to pass inside the burner inlets 111a, 111b, and thus vary the mixture of air and gas directed towards the gas burner 100.
    In order to be able to have a precise fit and coupling between the plate 62 of the ear 60 and the inlet port 112a, 112b respective of the burner inlet 111a, 111b, the arrangement 300 comprises a spring 70 for each outer conduit 30a, 30b, and in this embodiment of the arrangement 300 a support element 80. The support element 80 is a piece of malleable material, of aluminum, but can also be of copper or of an aluminum alloy with bronze or other alloys. The support element 80 comprises a central plate-shaped body that forms a support fin 81, and at the two ends of the support element 80 two holes are made. These two holes, made for example by cutting and drawing, surround the respective outer ducts 30a, 30b. These holes have a fin, substantially orthogonal to the support fin 81, which conforms to the body of the outer ducts 30a, 30b. The support flap 81 protrudes orthogonally from the outer ducts 30a, 30b, and allows the spring 70 to be supported between said support flap 81 and the bottom of the plate 62 of the ear 60, around the adjustment mouth 61.


    In order to fix the support element 80 in the outer ducts 30a, 30b, and thus avoid undesirable displacements in the operation, in this embodiment of the arrangement 300 both the support element 80 and the outer ducts 30a, 30b are deformed into a surface area. Thus, the fin surface of the holes of the support element 80 and of the outer ducts 30a, 30b are deformed, in this embodiment of the arrangement 300, in an area of the surface contour where the gas injectors are located 40a, 40b with respect to the surface contour of the outer ducts 30a, 30b. This contour zone is the deformation zone 42a, 42b for the gas injectors 40a, 40b and the deformation zone 32a, 32b for the outer ducts 30a, 30b, in the deformation between the outer ducts 30a, 30b and the injectors 40a , 40b, and is a deformation zone 39a, 39b for the outer ducts 30a, 30b, and a deformation zone 80a, 80b for the support element 80, in the deformation between the outer ducts 30a, 30b and the support element 80, but in this embodiment of the arrangement of a valve 200, the support element 80 is deformed into a deformation zone 80a, 80b, which spatially coincides with the deformation zones 42a, 42b, 32a, 32b, and 39a, 39b , so that the deformation zone 39a, 39b is equivalent to the deformation zone 32a, 32b. In other embodiments of arrangement 300, the deformation zones 32a, 32b and 39a, 39b are different. This deformation of the surfaces is carried out by the crimping-pressing technique, already defined above. In the embodiment of the arrangement 300 shown, the deformation zones 42a, 42b, 32a, 32b or 39a, 39b, and 80a, 80b are a semicircular groove, viewed from the outer face, or are a projection, viewed from the inner face , of the outer ducts 30a, 30b, and of the fins of the holes of the support element 80, and is a semicircular groove seen from the outer surface of said gas injectors 40a, 40b, since it is prevented from protruding as a projection in the inner surface, which contour each of the surfaces of the injectors, the outer ducts and the support element. The projection formed on the inner surface of the fins of the support element 80 fits into the groove formed on the outer surface of the outer ducts 30a, 30b, and in turn the projection formed on the inner surface of the outer ducts 30a, 30b fits in the groove formed on the outer surface of the gas injectors 40a, 40b, and all the parts are fixed.
    In other embodiments of arrangement 300 (not shown in the figures), for example


    when said arrangement comprises three outer ducts, the support element comprises three support fins distributed substantially in a triangle, contouring and fixing with their holes the three outer ducts. The fixing of the support element to the outer ducts would be as explained above for arrangement 300
    5 shown in Figures 5 and 6, as well as the support of the corresponding springs.
