Abstract
The present invention relates to a piston pump, which is in particular appropriate for the pressure fluid delivery in electronically controlled brake systems, including a housing, a suction valve, a pressure valve, and a pump piston that is designed as a stepped piston having a large-diameter portion and a small-diameter portion. According to the present invention, the stepped piston at its large-diameter portion is guided in a pump cartridge. Preferably, the pressure valve is designed additionally at the cartridge in a radial direction relative to the direction of movement of the stepped piston.
