Abstract (en)
An hydraulic actuator (10) having a housing (11) with a piston (13) slideable in the housing and a push rod (15) extending from one end of the housing a bellows (40) encircles the push rod and is secured at one perimeter (41) to the housing and at a second perimeter (43) engages a formation on the push rod (15) to retain the push rod in a predetermined extension position relative to the housing (11) during delivery of the actuator from the manufacturer to the end user. Actuation of the actuator after connection to an associated hydraulic circuit is arranged to disengage the second periphery (43) of the bellows from the formation (44) on the push rod (15) to allow free movement of the push rod relative to the housing thereafter <IMAGE>
