Abstract

Improvements in floating pistons, used as separators between two fluids such as a gas and a liquid, particularly in oleopneumatic monotube shock absorbers, in which said separators move inside cylinders under the effect of a pressure difference and are made up of an element made of rubber or an analogous material combined with a metallic reinforcement, characterized in that the floating piston comprises at least one sealing cord, each of which extends over a small part of the axial height of said piston, constituting said sealing cord or cords one piece with the rubber parts of the piston and having a diameter greater than that of the cylinder in which the piston slides, so that it is subjected to a certain tightness when mounted on the cylinder, being arranged the metal reinforcement with respect to the sealing cords in such a way that it ensures direct or individual straightly guiding said plunger.
