Abstract

A valve plate for a fluid pump includes a body having a first surface and an oppositely disposed second surface. The body defines a first kidney slot that extends through the first and second surfaces and a second kidney slot that extends through the first and second surfaces. A first notch is disposed in the first surface of the body and extends outwardly from the first kidney slot in a direction toward the second kidney slot. A second notch is disposed in the first surface and extends outwardly from the first kidney slot in a direction toward the second kidney slot. The second notch is separated from the first notch.

Description

Technical field [0001] The present disclosure relates to a fluid pump having a rotating group, and more particularly, to such a valve plate for a fluid pump. Background technique [0002] A valve plate for a fluid pump, the fluid pump to expand the pumping chamber providing a fluid path and providing a fluid discharge from the pumping chamber contractions. Although the fluid pump in the valve plate has been improved over the years, but the noise and damage due to cavitation caused problems still exist. Inventive content [0003] An aspect of the present disclosure relates to a valve plate for a fluid pump. The valve plate includes a body having a first surface and a second surface oppositely disposed. Extending through the body defines a first surface and a second surface of the first kidney-shaped groove extending through the first and second surfaces of the second kidney-shaped groove. A first recess provided on a first surface of the body, and the shaped groove extends outwar...
