Cylinder with freely controllable piston locking, has divided working piston and secondary piston between piston and rod with its own compressed air feed and conical sprung locking plates

摘要

The cylinder has a divided working piston and a secondary piston (1) between the piston and rod (5) with its own compressed air feed and conical sprung locking plates (2). The secondary piston is axially movable by compressed air and returns to its initial state by the spring action of the locking plates when the piston chambers are vented.
