ABSTRACT:
A hydraulic pump drive system for an automotive vehicle employing a starter motor to drive the hydraulic pump. The drive shaft of the starter motor is connected to the impeller of the pump, and can be engaged to the engine flywheel to start the engine. A control circuit is provided to connect the armature and the field winding or field windings of the starter in series for starting the engine and in parallel after the engine has been started. The control circuit also controls a valve in the hydraulic system which acts as a pressure-relief valve to minimize load due to the hydraulic pump on the starter motor during engine starting.
