ABSTRACT:
The present invention is directed to pulse dampener devices of the type employed to dampen pulses within hydraulic systems such as result from the use of pumps of the piston type. The device includes a pressure vessel having a movable partition therein, dividing the vessel into two chambers, each having a port in communication therewith, respectively a gas port for charging a gas under pressure into one said chamber and an oil port for connection to the hydraulic line. The device is characterized by an improved fitting which is subject to economical manufacture and which provides both the mounting means and the necessary hydraulic connection to the hydraulic system, while at the same time affording improved pulse dampening operation.
