ABSTRACT:
A gas or liquid pulsation dampening system is provided which minimizes the size of the vessel required to effectively dampen gas or liquid pulsations while maximizing the dampening effect. The gas or liquid pulsation dampening system comprises a novel spring pulsation dampening valve and a vessel for housing the valve and for containing a gas or liquid. The vessel is equipped with a pulsating gas or liquid inlet and a dampened gas or liquid outlet, and a support for holding the spring pulsation dampening valve in axial alignment with the dampened gas or liquid outlet. The spring pulsation dampening valve comprises first and second ends, a stationary outer sleeve, and a spring loaded gas or liquid flow restricting tube positioned in the interior of the stationary sleeve for axial movement therein. The gas or liquid flow restricting tube includes a gas or liquid intake at the first end of the pulsation dampening valve and a gas or liquid outlet at the second end of the pulsation dampening valve, and a spring operated pressure receiver at the gas or liquid intake for receiving and sensing gas or liquid pressure.
