Fluidic device e.g. fluid-actuated cylinder for controlling fluid flow valve, has sealing sleeve whose wall thickness in force introduction region is lowered based on wall thickness increased axially in both directions

摘要

The device (1) has a sealing element (18) that is arranged in an annular gap (17) coaxially within an inner portion (4) and fixed to an outer portion (2). The outer circumferential surface (22) of the inner portion is pressed by a radially braced rubber-elastic pressing element (25) in an annular sealing zone. The sealing element is formed as a sealing sleeve (24) and a radial outer circumferential surface is contoured such that the wall thickness of the sleeve in a force introduction region is lowered based on the wall thickness increased axially in both directions.
