SINGLE ACTION CYLINDER Abstract Of The Disclosure A single action cylinder is used with a machine. The machine has a first part and a second part having reciprocating motion relative to each other. The single action cylinder affects the reciprocation between the first and second parts. The cylinder includes a base adapted for attachment to one of said parts. The cylinder includes a plurality of open ended longitudinally extendable resilient actuators stacked one above the other. A first actuator of said actuators has one end connected to the base. Each of the actuators is interconnected to an adjacent actuator to allow a fluid to flow between the actuators. A second actuator of the actuators has one end connected to an apparatus for attaching the second actuator to the other of the parts. An elongated guide is connected to one of the actuators to limit movement of that actuator in a direction transverse to the length of the guide. One actuator has one end not connected to the guide but rather that end is free to move in all directions relative to the guide to allow the cylinder to affect reciproca- tion between the parts without creating extraneous loading on the first and second parts because of improper alignment between the first and second parts and the single action cylinder.
