摘要

A lift buffer has a gas spring acting to provide the recoil force on the buffer plunger (23). The gas spring chamber is within the buffer plunger (23). The gas spring rod (32) is urged against the buffer base (10) by the gas pressure and carries a disc (38) at its lower end. A vent hole (19) in the base (10) vents from between the disc (38) and the base (10) to the annular low pressure liquid reservoir that surrounds the ported tube (13).
