Abstract

Improvements in the hydro-pneumatic energy absorbers, constituted by a hydropneumatic energy absorber for use particularly in the shock absorbers of motor vehicles, of the type comprising a first cylinder that is divided by a floating piston in two adjacent chambers, one of which it is filled with gas and the other with liquid, a second cylinder external to the first and mounted so that it can be slid with a sealing fit with respect to the first, which is completely filled with liquid, the two chambers being filled with liquid, the first and second cylinders, placed in communication with each other through a hole whose opening varies depending on the relative position of the two cylinders, said hole being in a transverse partition that constitutes the bottom of the first cylinder and which exerts its function together with a variable section pin that is fixed to the second cylinder, characterized in that the transverse partition or butt (3) that subsequently closes the first cylinder (1) comprises two discs coupled together (3a, 3b) made of stamped sheet with a hole in the center and with a profile that, when coupled together, constitute a cavity transverse (3c) in which a ring (4) is housed whose central hole (4a) is calibrated and which has freedom of transverse displacement so that it is always centered with respect to the variable section pin (7) that is fixed to the cylinder head (6) of the outer cylinder (1), said two discs (3a, 3b) being fixed to the inner cylinder by a flanging of the rear end of the side wall of the cylinder (1a) itself.
