Abstract

PURPOSE:To permit a piston rod to perform a 3-position control accurately by fitting a 2nd piston movably to a piston rod, and providing an air pressure supply port in the vicinity of the end parts of air chambers in a cylinder and the center portion thereof. CONSTITUTION:A 1st piston 5 is attached rotatably to a piston rod 1 by means of stop rings 7, 8 so as not to be allowed to move axially, a 2nd piston 15 consisting of large, medium-sized, and small diameter portions is movably inserted in the axial direction into the piston rod 1, and air pressure supply ports X, Y, Z are provided in the vicinity of the end parts of air chambers A, B in a cylinder 21 and its center portion. Hence positioning the 2nd piston will allow the 3-position control of the piston rod 1 and its reciprocating motion.
