Abstract

PURPOSE: To enhance durability of a valve by making a valve port in the head wall of a cylinder and supporting a valve disc for opening/closing the valve port selectively on a valve operating member through a resilient body. CONSTITUTION: Exhaust openings 21 are made at two peripheral points in the head wall 2 of a cylinder 1 in the circumferential direction. A valve operating member 22 is interposed between the head wall 2 and a piston 14 such that it can slide in the axial direction along the inner surface of the cylinder 1. A bottomed hole 23 having larger diameter than the exhaust opening 21 is made in the valve operating member 22 oppositely to the exhaust opening 21. A presser 27 is set in the hole 23 while being fitted, to the shaft part 25 thereof, with a valve disc, i.e., a tubular seal pad 28. A coil spring 29 is interposed between the flange part 26 of the presser 27 and the bottom wall of the hole 23 applied with a cover plate 30 having a hole for projecting the seal pad 28.
