Abstract

Sealing device for lift piston rods and the like, particularly for vehicle suspension, of the type that ensures the sealing of the passage of said rod through an end wall of the limiting cylinder of a high pressure annular chamber that surrounds that rod piston inside said cylinder, characterized essentially by consisting of a mechanical clamping joint interposed between this annular chamber and a cavity that surrounds the piston rod, said joint being moderately tight in order to reduce the friction it exerts on that rod, with a lip seal that separates said cavity from the outside and arranged so that its lip is applied against the aforementioned piston rod by the pressure of this same cavity, and with means to maintain in such cavity an intermediate pressure between that of the aforementioned annular chamber and the exterior, and sufficient to ensure absolute sealing of the joint lip.
