Abstract

The device which gives a determined variation in the position of one or more rams. There is a cylinder (1), internally ground between the ram ends (2, 3) and also a piston (11) and rod (10) in the cylinder. A mobile stop at the bottom of the ram slides in a guide system (14). The stop is moved mechanically and has on its front face a recess (22) for a shock absorber (18) fitted on the side of the piston. The movement of the stop is a rear bearing (27) and a screw (28) and nut (24) on the rear face of the stop. The screw is motor driven.
