Beschreibung
Zusammenfassung:	A constructionally simplified hydraulic pump has two pump elements which discharge from a common suction chamber. The flows can be alternatively fed in common to a pressure outlet or separately to two outlets, one of which outlets leads back into the suction chamber. The pressure-side chambers for the separated flows can be connected, via a unidirectional valve, through which, in the open state, the flow of one pump element can be united with that of the second pump element. The different flow guide modes are switched via control valves whose position depends only on the pressure prevailing at the pressure outlet of the hydraulic pump. The control valves to be switched are a common component of a single control slide valve.
