ABSTRACT:
A surge chamber hydraulically connected between the outlet of a radial piston pump and the internal chambers of the piston plungers, cooperates with a second fluid storing surge chamber in the pump housing through connecting passages to dampen vibrations produced by pump flow fluctuations to reduce non-uniform flow and the noise level during pump operation under a wide range of pressures and speeds.
