Abstract
A piston sealing arrangement for pressure-fluid-operated systems is disposed in an annular recess of a piston (5) or an associated housing (4) and is composed of a sealing ring element (1A, 1B) as well as an elastic element (2, 3) acting on one side in opposition to the direction of the pressure force (A). Herein the elastic element is dimensioned such that the sealing ring element (1) moves against its elastic element (2, 3) at a pressure smaller than the force against which the piston (6) is moving and by which it is kept on its stop, a pressure-fluid film being formed as a result which safeguards a uniform initial movement of the piston to a largest possible degree.
