Abstract

A hydraulic pressure responsive accessory, such as a cavitation eliminator for a hydraulic system, comprises a casing 12 having an inlet 22 for connection to the hydraulic system, and an easily replaceable gas filled flexible bladder 44 which compresses and expands in response to pressure fluctuations in the system. The ends of the bladder are releasably secured to the casing end cap 16 and end wall 20 by securing means 52, 54 accessible externally of the casing. A leaf spring 200 is provided between the bladder 44 and a grid 26 overlying casing inlet openings 24 thereby to protect the bladder 44 from impact damage with the grid 26, and means 210 connected with the leaf spring provide indication of excess bladder pressure or automatic release of excess pressure. <IMAGE>
