<p>This invention relates to an improved pressure pulse dampener device comprising a pressure vessel having a movable partition therein dividing the vessel into two chambers, each chamber having a port in communication therewith, namely, a gas port for charging one of said chambers with gas under pressure and an oil port. The oil port is rigidly secured to a hollow fitting having an inlet and an outlet port, with means interposed between the ports for diverting the flow toward the oil port, the device being characterized by the provision within the fitting of an expansion chamber having a progressively increased cross section area juxtaposed to a baffle interposed between the inlet and outlet ports, the chamber providing improved dampening characteristics.</p> |
