ABSTRACT:
A fluid pressure operated actuator has a cylinder with a removable end cap and a piston rod extending axially through the end cap for transmitting piston movement to an external load and also has an internal compressed spring biasing the piston rod towards a predetermined position. To prevent violent expulsion of elements by the compressed spring upon removal of the end cap, stop means are provided on the piston rod to limit relaxation of the spring prior to the time that the end cap is fully removed from the cylinder.
