Elastomer seal, especially for sealing between a piston and a cylinder of a clutch has a cross section with two zones which respectively fulfill a sealing function and reduce the radial compressive stresses

摘要

The elastomer seal (1), in particular, between a piston (6) and a cylinder (8) of a clutch has a cross section comprising zones (2, 3) which respectively serve for sealing the pressurized space (9) and for reducing the radial compressive stresses and keeping them constant over the range of working temperatures.
