Abstract
A piston pump for delivering fluids includes a cylinder, a piston that is movably mounted in the cylinder, and a pressure chamber that is arranged between an inlet valve and an outlet valve and that is closed off by a cover. The piston pump further includes a throttle element that is disposed in the fluid flow downstream of the outlet valve and that is configured to throttle the fluid flow. The throttle element is in the form of a resiliently elastic disk that is inserted into the cover. The cover further includes a mechanism configured to pre-center the throttle element.
