Abstract

A body (15) has a cavity (16) supplied with compressed air, and a stem (20) slides in axial holes (18, 19) and supports a piston (21) moving in a cylinder (8). An exchanger (24) has an axial through hole that accommodates a narrow portion (26) of the stem, and has elastic support arms (30) on a wider end portion (34) that receives a wider end portion of the piston. The axial through hole has a wider end portion that accommodates a non-narrow part of the stem during the return stroke.
