ABSTRACT:
The actuator piston has a generally cylindrical central projection about the exterior of which a similarly formed rolling diaphragm is closely fitted. The piston rod can turn freely, to avoid any twisting of the piston and diaphragm, and can also be axially withdrawn from its engagement with the piston. Return spring means extends into the diaphragm enclosed part of the piston.
