摘要

A piston pump, in particular for a hydraulic assembly of an electronically controllable vehicle brake system, includes a cylinder element that has a pressure chamber with an outlet formed on the inside. The piston pump further includes an outlet-restricting element held on the outside of the cylinder element on a component by a first holder.

主权项

1. A piston pump, comprising:
a cylinder element forming a delivery chamber with an outlet on an inside of the cylinder element; and an outlet valve outside the cylinder element and hydraulically downstream of the delivery chamber, the outlet valve including:
a component defining a plurality of openings and having a first mount region; andan outlet-restricting element positioned over the plurality of openings and mounted at the first mount region of the component in such a way that fluid passing through the plurality of openings bends the outlet-restricting element such that a radially outer portion of the outlet-restricting element deflects away from the plurality of openings in an axial direction by a greater axial distance than a radially inner portion of the outlet-restricting element, wherein the radially inner portion of the outlet-restricting element is fixed axially such that the radially inner portion does not move when the radially outer portion deflects.
