    [0001] The present invention relates to a pump, for example a water pump for a water circuit of a motor vehicle. Pumps and in particular water pumps are used in motor vehicles, for example to supply the water cooling means circuit, for cooling the motor vehicle and, where appropriate, also for other groups. In this case, the cooling water circulates through the drive motor and is heated therein. The cooling means flows through a cooling means radiator where it is again cooled by heat exchange, for example with air, before it is again fed from the pump to the engine. 'training. In this case, however, the required pumping power of the pump is not always in the maximum range, but can also be reduced depending on the operating state of the motor vehicle. The pumping power may, however, in particular depend on the drive. If, however, the pump is itself driven by the drive motor, the number of revolutions of the pump is defined by the number of revolutions of the drive motor, which must not, however, be able to correlate with the power of the drive. pumping required. That is why it is desired in principle to use an adjustable pump. Very expensive solutions, however, are quite unsuitable for motor vehicle applications, since they also increase costs systematically, which is not acceptable in the automotive industry. DE 10 2010 005 731 A1 discloses a pump having an extraction member and a valve member disposed downstream thereof and constructed as a pusher or a twister. Adjustment means makes it possible to control, but adjustment of intermediate positions is not satisfactory with each adjustment means. WO 2013 120543 A1 discloses a pump having a valve member disposed downstream of the pump wheel that can be adjusted between two end positions by means of a vacuum chamber. However, this does not offer a good adjustment capacity because the vacuum chamber can not generally be well brought into intermediate positions or be maintained there.
    [0002] The object of the present invention is to create a pump that can be constructed simply and economically while providing a good adjustment capacity. This objective is achieved with a pump having a pump casing with a suction opening and an exhaust opening, with a pumpable impeller arranged in the pump casing, by means of which a fluid can being transported from the suction opening to the exhaust opening, a valve member being provided in the pump housing, the valve member being adjustable by an actuator, to adjust the flow of fluid transported by the pump, characterized in that the adjustment of the valve element can be influenced by a magneto-rheological braking element. An exemplary embodiment of the present invention relates to a pump having a pump housing with a suction opening and an exhaust opening, with a pumpable impeller, disposed in the pump housing, and a pump housing. aid from which fluid can be conveyed from the suction opening to the exhaust opening, a valve member being provided in the pump housing, the valve member being adjustable by an actuator, for controlling the fluid flow extracted by the pump, the setting of the valve member being influenced by a magneto-rheological braking element. The valve element can thus be advantageously adjusted in each operating position by the controllable interaction of the actuator and the braking element, as well as potentially being set for a predefinable duration, even when the actuator can only be adjusted in the short term or unstable in intermediate positions. In this case, it is particularly appropriate that the actuator is a pressure actuator or underpressure (depression) that can be used to adjust the valve element. The actuator can thus be a hydraulic or pneumatic actuator that can be supplied with pressure or underpressure, in order to move and / or adjust the valve element. Such actuators can in this case be actuated between two end positions, intermediate positions can also be adjusted for short durations. In this case, it is particularly advantageous for the actuator to be a vacuum chamber. Such vacuum chambers 5 can be made simply and at a good price and are therefore readily used, particularly in the automotive industry. It is particularly advantageous that the valve member is rotatably disposed in the housing. This provides a kind of torsion pusher or torsion valve for simply controlling the extracted fluid flow from a maximum fluid flow to a minimum fluid flow by rotating approximately 90 °. In this case, the maximum fluid flow is the fluid flow allowing the pump to achieve maximum extraction and the minimum fluid flow can for example also be a zero fluid flow, when the valve completely interrupts the flow of fluid. An intermediate position can then correspond to a fluid flow comprised between the maximum fluid flow and the minimal fluid flow. It is particularly advantageous that the actuator is an essentially linearly controllable output member acting through an actuating mechanism on the valve member rotatably disposed in the housing. This allows a rotational movement of the valve element through a simple actuator embodiment. This reduces the costs of the actuator because of its simple construction, while at the same time allowing safe control, since the adjustment of the valve element can be carried out simply. The actuator comprises an essentially linearly movable output element acting via an actuating mechanism, for example, a lever, on the valve element arranged to be rotatable in the housing. pump. In this case, it is also advantageous for the actuating mechanism to be a lever mechanism. This makes it easy and safe to control the actuator at the valve member while providing safe control throughout the operating life. It is also advantageous if the magneto-rheological braking element is connected to and acting on the valve element. This makes it possible to transmit a direct action of the braking element to the valve element, which results in rapid and direct action without external influences. It is also advantageous if the magneto-rheological braking element is connected to the actuating mechanism and acts on it. This makes it possible to simply integrate the magneto-rheological braking element into the actuating mechanism, which makes it possible to illustrate advantages in terms of size and can be simplified with respect to the assembly. It is also advantageous if the magneto-rheological braking element is connected to the actuator, in particular to the output element of the actuator and acts on it. This also makes it possible to create a well-mountable construction unit that can be easily and economically realized. It is also advantageous that the valve element is rotatably disposed in the pump housing, the magneto-rheological braking element meshing with it at an opposite side of the valve element. in the form of the actuator. This allows good space distribution to be achieved when the two elements meshing at the valve member are mounted to the housing at opposite sides. The present invention will be explained in detail later with the aid of an exemplary embodiment, with reference to the drawing, in which: FIG. 1 illustrates a schematic representation in perspective of an exemplary embodiment of a pump according to the invention; Figure 2 illustrates another representation of the pump according to Figure 1; Figure 3 illustrates a partial sectional representation of the pump according to Figure 1; Figure 4 illustrates a sectional view of the pump according to Figure 1; Figure 5 illustrates a representation of a pump according to the invention with a fully open valve element; Figure 6 illustrates a representation of a pump according to the invention with a valve element only partially open; Fig. 7 illustrates a representation of a pump according to the invention with a fully closed valve element; FIG. 8 illustrates a diagrammatic representation in perspective of another exemplary embodiment of a pump according to the invention; and Fig. 9 illustrates a representation of a vacuum chamber with a magneto-rheological braking element in the form of an actuator for adjusting the valve member of the pump according to Fig. 8.
    [0003] FIGS. 1 to 4 illustrate, in different representations, an exemplary embodiment of a pump 1, for example in particular a cooling medium or water pump, in particular for a motor vehicle. The pump 1 comprises in this case a pump housing 2. The pump casing 2 comprises in this case at least one suction opening 3 and at least one exhaust opening 4. The pump casing 1 can variant comprising more than one suction opening 3 and / or more than one exhaust opening 4. In the embodiment of Figures 1 to 4, the pump casing is partly made approximately 20 tube-shaped , the exhaust opening 4 taking the form of a tubular opening in the longitudinal direction of the approximately tubular portion of the pump housing 2. The suction opening 3 is in the form of a sleeve of tubing extending approximately in the radial direction to the approximately tubular portion 25 of the pump casing 2 and is connected thereto. A pump wheel 5 is disposed inside the pump casing 2, said wheel being followed in the axial direction by a pressure stage 6 and a sealing body 7. The pump wheel 5 is at 30 advantageously achieved in the form of a paddle wheel. The pump wheel 5 is housed on a shaft 8 rotatably disposed in the pump housing 2. The shaft 8 is in this case axially out of the pump housing 2 where the shaft 8 is connected. 9. The belt disk 9 is connected in a drive connection with a belt not shown of a belt drive, so that the pump wheel 5 is thus driven into the pump housing 2. The pump wheel 5 serves to transport a fluid, for example water or a cooling means, from the suction opening 3 to the exhaust opening 4. In the In this instance, the transport amount of the pump 1 depends, among other things, on the driving power and / or the number of driving revolutions used to drive the pump wheel. An additional valve member 10 is provided to further control the amount transported, hence the volume flow rate of fluid. This valve element 10 is disposed downstream of the pump wheel 5 in the approximately tubular portion of the pump housing 2.
    [0004] The valve member 10 is formed as a torsion pusher having an approximately spherical shape 11 through which a passage channel (or through channel) 12 is formed. The valve member 10 is rotatably disposed in the housing with two pins 13 so that the passage channel 12 is released and the maximum transported volume flow rate or channel 12 is closed and no volume flow is carried. Intermediate positions are also possible in which the volume flow rate can vary. In this case, the valve member 10 is disposed following the seal body 7 serving as a seal between the pump housing 2 and the valve member 10, especially when the valve member 10 is adjusted. with a passage channel 12 closed. An influence is applied from the outside on the valve element 10 via the two pins 13. The (first) pin 13 makes it possible to turn the valve element 10 via a lever 14. An actuator 15 is provided for this purpose. end, said actuator being made in the embodiment of Figures 1 to 4, in the form of a vacuum chamber. The actuator 15 comprises in this case an output member 16 that can slide lengthwise, such as a slide connected to the lever 14, to rotate the valve member 10. If the vacuum chamber is energized Underpressure (depression), the output member 16 slides and the valve member 10 is moved. As a variant, the actuator 15 may also be made differently, for example in the form of a pressure or underpressure (vacuum) actuator, in this case in particular in the form of a pneumatic or hydraulic actuator. The adjustment of the valve element 10 is thus effected in this case by the actuator 15. A braking element 17, for example in particular a magneto-rheological braking element 17, is provided at the level of the valve element 10. the other (second) pin 13 for influencing the movement of the valve member 10. In this case, the movement can be stopped, so as to lock the valve member 10 in one position. In this case, the braking element 17 comprises a casing or casing in which a magneto-rheological material is housed. A piston member is also provided in the housing, said member moving through the magnetorheological material as the pin 13 moves. When a defined magnetic field is then applied, the elements of the magnetorheological material are linked together and the viscosity of the magneto-rheological material increases. This induces a force action on the piston member and the movement of the valve member 10 experiences a braking force, the braking force then depending on the applied magnetic field. This can lead to a blockage of the movement of the valve member 10. The magnetorheological material can in this case be a dry powder or a fluid containing magneto-rheological elements. The position of the valve element 10 in the pump casing 2 is thus controlled by interacting the actuator 15 with the braking element 17. FIGS. 1 to 4 illustrate an exemplary embodiment equipped with an actuator 15 having an output member 16 substantially movable in a linear manner and actuating, via an actuating mechanism, the lever 14 on the valve member 10 rotatably disposed in the pump housing 2 Other actuating mechanisms may also be provided alternatively. The magneto-rheological braking element 17 is directly connected to the valve element 10 and thus acts directly on it.
    [0005] Alternatively, the magneto-rheological braking element 17 could also be connected to the actuating mechanism and act on it to allow the position of the valve element to be changed. Figures 5 to 7 illustrate the pump 1 of Figures 1 to 4 in different operating positions. The valve member 10 is so adjusted in FIG. 5 that the passage channel 12 is free. The flow rate of fluid that can be transported is thus not influenced and / or reduced. The valve member 10 is so adjusted in Figure 6 that the passage channel 12 is only partially released. The volume flow rate of transportable fluid is thus reduced. The valve member 10 is so adjusted in FIG. 7 that the passage channel 12 is fully blocked. The volume flow rate of transportable fluid is thus interrupted. FIG. 8 illustrates an exemplary embodiment of a pump 100 in which the braking element 117 is integrated in the actuator 115. The pump 100 is otherwise produced in a similar manner to the pump 1 of FIGS. 1 to 4; which makes any repetition superfluous. Figure 9 illustrates the relative actuator 115. The actuator 115 comprises a casing 120 with a membrane 121 disposed inside, said membrane defining a pressure chamber 122 together with the casing 120 being able to be supplied with pressure or under-pressure via a connection 124. A slide 125 made in the form of an output member is connected to the diaphragm 121, so as to be able to move the slider in the event of pressure or underpressure being introduced into the pressure chamber 122. A spring 123 is furthermore provided. in the pressure chamber 122 with which the slider can be fed with force. If no pressure or underpressure is applied, the spring loads the slider into a defined position, called fail-safe position. The braking member 117 is provided at the actuator 115. It includes a housing 126 with a chamber 127 in which magneto-rheological material is housed. A piston member is connected to the slider 125 and is provided in the chamber 127, which member moves through the magnetorheological material. Application of a magnetic field through a magnetic field producing means 128 changes the viscosity of the magnetorheological material, thereby controlling the position of the slider 125 embodied as an output member in interaction with the supply of pressure or underpressure.
