Hydraulic aggregate e.g. for motor vehicle braking system, has body with electro hydraulic valves and hydraulic pump with channels connect pump with hydraulic load

摘要

The hydraulic aggregate (HCU) has a body with electro hydraulic valves, and a hydraulic pump. Channels connect the pump with a hydraulic load. In the body, a pulse damper (18) is integrated and assigned to the pump. An element (31) made from flexible material, separates a fluid chamber (30) from a pneumatic chamber (32). The pulse damper is between a pressure side of the pump and the hydraulic load, and the separating element has a bore catch (33). The fluid chamber has a mounting hole (29) in the body and in the separating element.
