Abstract
A valve/pump unit having a single electric motor for driving at least one pump stage and for adjusting a multiway valve, a reduction gearbox, which is driven by the electric motor, at least one first pump stage which is driven by the electric motor for conveying a heat transport medium in a first heat transport medium circuit, an adjustable multiway valve that is adjusted via the reduction gearbox, and having heat transport medium channels for providing at least two switching positions between the first heat transport medium circuit and a second heat transport medium circuit. In pumping operation in a first direction of rotation of the electric motor, the reduction gearbox is uncoupled from the electric motor via a freewheel. The reduction gearbox is operated in a second direction of rotation of the electric motor, opposite to the pumping operation, to adjust the multiway valve.
