Abstract

The system drives a main piston at high speed from the base of a tubular casing and a stop at the other end and returns it to the base again. Gas under pressure is delivered from a receiver to between the base and the piston, which is coupled by a rod to a secondary piston, working in a second and closed tubular casing so as to form a first chamber contg. the rod and second one on the opposite side of the secondary piston. The first chamber (9) incorporates an annular piston (20) sliding between the rod (7) and the wall of the casing, so as to form in this chamber two spaces (21, 22) sealed off from each other. The first (21) communicates permanently a passage in the rod with the receiver (15), and is between annular and secondary (6) pistons. The second (22) on the opposite side of the annular piston is connected selectively to a pressure supply (24) and to a discharge (28) by means of a distributor valve (29).
