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.

The invention relates to a pulsation damping capsule (11, 11', 11''), comprising at least one hermetically joint-sealed metal membrane housing made of at least two preferably concave hemispheres (13, 14; 22, 23), said housing being provided for separating an inner space (16) from a surrounding pressure medium, wherein the hemispheres (13, 14; 22, 23) are connected together along a peripheral seam (17) firmly bonded such that the pulsation damping capsule (11, 11', 11'') can be compressed and expanded as an energy accumulator with spring elasticity due to the effect of the pressure medium, in particular pressure medium pulsation. A pulsation damping device is provided which is both dimensioned to withstand stresses and is simple to produce, the pulsation damping effect of which can be tailored especially easily to the existing conditions. Further disclosed is a pulsation damping module for housing a plurality of pulsation damping capsules.
