These pulsations can lead to system damage through check valve failure, tubing or hose rupture, loosened connections and cracked manifolds. In addition to the potential for system failure, hydraulic pressure pulsations can dramatically increase noise levels within the aircraft cabin. Unlike nitrogen-charged “muffler” devices, Essex hydraulic pulsation dampeners contain no moving parts and require no servicing. Constructed of high-strength 15-5PH hardened steel, these units are subjected to non-destructive tests prior to shipment.
