An arrangement for the manoeuvring/positioning and securing of a piston (3) against a corresponding cylinder pipe (5), for example with hydraulic cylinders, whereby both the positioning element (1) and the tightening element (2), situated in their separate grooves (4, 10) on the piston (3), give radially directed power to effect a definite contact between the elements (1, 2) and the cylinder pipe (5) and thereby retain good positioning and securing of the piston (3) as well as having a protective role within the pressure area against possible pollutants, metal particles, sand etc., by hindering damage to the securing element (1), the protective plates (9), the tightening ring (8) and the cylinder pipe (5)<IMAGE> |
