ABSTRACT:
A combination high pressure pump/attenuator suitable for use in vehicle control systems employs a high pressure pump outlet check valve located in the attenuator cavity and compressively loaded against its seat by the compressive force of a volumetrically and axially compressible attenuator element. In one preferred embodiment, the check ball is replaced by a projection molded into the attenuating element itself.
