Abstract
A valve pump unit having an electric motor, a reduction gearbox driven by the electric motor, a first pump stage driven by the electric motor, a second pump stage driven by the electric motor, a multiway valve adjusted via the reduction gearbox and having heat transport medium channels for providing at least two switching positions between a first heat transport medium circuit and a second heat transport medium circuit, and also a common housing section for accommodating the electric motor, the multiway valve, the reduction gearbox and also the first pump stage and the second pump stage. In pumping operation, the electric motor is rotated in a first direction, and the reduction gearbox is uncoupled from the electric motor via a freewheel. The reduction gearbox may be operated in a second direction of rotation of the electric motor, to adjust the multiway valve.
