Abstract (en)
[origin: WO2020011433A1] A piston pump (10), in particular a high-pressure fuel pump for an injection system of an internal combustion engine, having a piston (22) and a working chamber (24) which is delimited by the piston (22), wherein the piston (22) has a running surface section (26), via which the piston (22) is guided by means of a guide element (28), and is configured and developed in such a way that the running surface section (26) of the piston (22) tapers in cross section towards its end (32) which faces the working chamber (24).
