Abstract

Pneumatic cylinder, characterized in that it is constituted by a cylindrical sleeve joined to both front and back heads, housed therein a sliding tubular rod that, at its rear end, exceeds the corresponding head, and at its front end is coupled to a plunger with hole axial cross-section, being provided with an enguiamiento meeting that rubs in the inner face of the shirt and divides the same one in variable front and rear spaces, of an O-ring to stop with the rear head in the phase of maximum recoil, and of a front spring for. Shock with the front head in the phase of maximum advancement, the front head being mounted on a support plate, so that when air enters the tubular stem through a rear mouth, a passage of the same air through the hole of the plunger the anterior space of the shirt, with recoil of the piston and rod itself, the air coming out of the rear space through a rear hole of the sleeve, while in the opposite direction, when a push is exerted against the stem, it moves in advance until the piston reaches the previous head, after shock of the shock absorber spring in said head, this front head being a push-button that emerges through the head. Support plate, equipped with a safety valve that relates the anterior space of the jacket to the outside, said valve having that said button being pressed, a communication of said anterior space with the outside is determined in order to immobilize the stem.
