Piston pump for delivering fluids, and corresponding assembly process for a piston pump

摘要

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.

1. A piston pump for delivering fluids, comprising:
a cylinder; a pressure chamber closed by a cover; and a throttle element disposed in a fluid flow downstream of an outlet valve, the throttle element being configured to throttle the fluid flow, wherein at least two pressing lugs are formed on the cover, wherein the cylinder is pressed against the at least two pressing lugs in a pressing-in direction, wherein at least one recess is formed between the at least two pressing lugs, the at least one recess acting as a discharge channel for the fluid flow, wherein the throttle element is configured as a resilient disk inserted in the cover, the cover including a centering mechanism configured to pre-center the throttle element, wherein the centering mechanism includes at least one chamfer arranged on each pressing lug of the at least two pressing lugs, the at least one chamfer arranged rearwardly in the pressing-in direction, and wherein the throttle element is deformable between a first configuration, wherein a portion of the throttle element contacts the cover, and a second configuration, wherein the portion of the throttle element does not contact the cover.
