Abstract
The invention relates to a piston pump with a piston (10) that is guided so that it can move axially in a pump bore (12) of a pump housing (14). In order to simplify the manufacture of the piston (10), the invention proposes providing the piston (10) with a support ring (64), which is connected to a guide ring (66). By connecting the support ring (64) and guide ring (66), the structural length of the piston pump (10) can be shortened.
