Abstract

The invention refers to a device having a piston (6) which is axially displaceable in a cylinder (5), and which by its displacement in the cylinder brings about a pressure change in a pressure medium. To obtain an improved sealing effect between the piston (6) and the cylinder wall (5) and for reducing the required volume of pressure medium to the smallest possible amount, the piston (6) is provided with a sealing lip (10) made integrally with its main portion, which sealing lip, under influence of the pressure of the pressure medium will be pressed into sealing contact against the cylinder wall. The surface (7) of the piston contacting the pressure medium is located in front of or approximately in the same plane as the outer edge of the lip (10). A groove formed between the surface (7) and the lip 10 is filled with resiliently deformable material 13. The surface (7) may be constituted by an unbroken layer of the resiliently deformable material. <IMAGE>
