ABSTRACT:
A regulatable drive for a motor vehicle, in particular for a water pump in a motor vehicle, has a rotatably mounted shaft, on which is located a rotatably mounted drive member and a rotationally fixed driven member. Between the drive member and driven member, a coupling region is defined, which can receive a viscous fluid for selectively coupling the drive member and driven member. The regulatable drive includes at least one first and at least one second flow path, which connect a fluid storage space to the coupling region, and it has a device which can be varied in its position by means of at least one actuator and which varies at least one passage orifice of at least one of the flow paths.
