Device, particularly hydraulic ram for pressurization of flowable medium in motor vehicle, has pressure generating unit comprises recirculation unit which returns back flowable medium into pressure generating unit

摘要

The device has a pressure generating unit (2) which sets a flowable medium under a pressure (P1). Another pressure genertaing unit sets the flowable medium under another pressure at a pressure outlet (48), where the latter pressure is higher than the former pressure. The two pressure generating units stands in flow connection by a connection valve unit (12), such that a flow of the flowable medium from the former pressure generating unit to the latter pressure generating unit is temporarily allowed. The former pressure generating unit has a recirculation unit which returns back the flowable medium, which does not reach the latter pressure generating unit, into the former pressure generating unit. An independent claim is included for a method for providing a pressurized flowable medium.
