Abstract

The invention relates to an electrically controllable pressure provision device (5, 5′), particularly for a hydraulic motor-vehicle brake system, comprising a stepped bore (54), which is arranged in a housing (53,21), and a piston (51), which can be actuated by an electromechanical actuator (35, 36). The piston (51), together with the housing (53, 21), delimits a pressure chamber (50). The piston (51) is constructed as a stepped piston, the smaller-diameter piston step (51′) of which enters the smaller-diameter step (54′) of the stepped bore after a specified actuation of the stepped piston, such that the pressure chamber (50) is subdivided into a first pressure chamber (55) and a second pressure chamber (56). The invention further relates to a brake system for motor vehicles having such a pressure provision device.
