Abstract
A piston pump assembly for pumping a fluid including a pump housing defining a bore. The pump housing further defines a fluid inlet and a fluid outlet and a fluid flow path extending therebetween for conveying the fluid from the fluid inlet to the fluid outlet. A piston is slidably disposed in the bore of the pump housing, and an eccentric engages the piston to propel the fluid through the fluid flow path. An inlet check valve and an outlet check valve body are disposed in the bore for only allowing the fluid to flow in one direction from the fluid inlet to the fluid outlet. A filter is disposed in the fluid flow path downstream of the inlet check valve and the outlet check valve body and adjacent to a damper orifice for filtering debris from the fluid before the fluid is conveyed to the fluid outlet.
