Abstract
A hydraulic pump system having a pump for pressurizing fluid and a hydraulic chamber for receiving fluid from the pump. An even flow of fluid is outputted from the chamber to a valve assembly. The chamber is formed from a resonator and a resonator cover that are attached in a fluid tight manner by elastic fasteners. The resonator cover acts as a pressure controller in that when the pressure of fluid is of sufficient magnitude, this force creates a gap for controlling fluid pressure output to the valve assembly.
