摘要

The control is for a hydraulic pump (3) motor (2) of a motor vehicle hybrid drive with an internal combustion engine and electric motor. There is a clutch assembly (5) with a hydraulically switchable clutch (6) and the control regulates the fluid (7) passed through the pump. The hydraulically switchable clutch has a control valve (8) for the pump fluid flow. The hydraulically switchable clutch can be brought into one position by a return spring (10).
