Abstract

A motor vehicle hydraulic pump (1) is provided comprising a gerotor rotor set or planetary rotor set and at least two output stages. A first output stage (10) of the hydraulic plump (1) is connected to a lubricant, in particular, a clutch lubricant. A second output stage (11) of the hydraulic pump (1) is connected to at least one clutch (2) of the actuation thereof. The invention also provides a method for actuating at least one clutch which is arranged in the motor vehicle by means of a motor vehicle hydraulic pump, whereby an inter-connection of a volume flow outlet of the first step (10) and the second step (11) of the hydraulic pump (1) takes place according to requirements for actuating the clutch.
