<p>A reversible spring return cylinder actuator having a pair of piston rods extending from a common spring load piston to the exterior of the housing. In a non-pressure position of the piston, one of the piston rods extends further from the housing than the other. Either piston rod and either end of the housing can be mounted to a device to be actuated so that the same actuator can be used to define a non-pressure extend or retracted actuator without disassembly of the actuator.</p> |
