Abstract

A piston arrangement for a piston pump having at least one piston (1) cylinder (2) arrangement, has the piston contacting a rotating drive element (3) via a piston shoe (10), the piston is tensioned via a spring (9) mounted to the piston via a support element (8). The support element has a retaining element (86), which can be brought into contact with the piston shoe and is located in the direction of the piston shoe. The piston shoe has at least one return spring at its circumference in which the retaining element is held. <IMAGE>
