Abstract:
PCT No. PCT/SE97/00349 Sec. 371 Date Sep. 4, 1998 Sec. 102(e) Date Sep. 4, 1998 PCT Filed Feb. 28, 1997 PCT Pub. No. WO97/33093 PCT Pub. Date Sep. 12, 1997A pneumatic piston-cylinder apparatus of single acting type which performs a working stroke in one working direction, and is returned to its initial position without any external supply of compressed air comprising a cylinder part with cylinder jacket (1), a front end (2), a rear end (3), and a piston (5) which is reciprocatable in the cylinder. Connected to the rear end (3) is a supply of compressed air and within the cylinder is a return channel (10) used for draining the air on the unloading side of the piston. Also, an upper channel (9), return air chamber (26), a second pressure channel (29) and compressed air chamber (30, are provided to build up a reserve amount of compressed air at the unloading side of the piston at the end of the working stroke through the action of a valve rod (27) connected to the piston (5) with a tubular valve slide (32) actuated by a spring (33) close to the end of the working stroke whereby channels (35,36) are opened between pressure chamber (23) and the reserve chambers to return the piston (5) to its initial position for the working stroke.
