Abstract
A motor vehicle pump arrangement has a first pump and a second pump, and an electric motor for driving the two pumps. The electric motor is drive-connected fixedly to the first pump and connected via a clutch arrangement to the second pump, in such a way that the first pump can be driven on its own and the first and second pump can be driven together. The first pump is configured as a reversible pump which can be operated in two rotational directions. A valve arrangement generates a uniformly directed fluid volumetric flow which is independent of the rotational direction being provided for the first pump in a fluid circuit. The clutch arrangement is configured as a freewheeling clutch, via which the electric motor is drive-connected to the second pump.
