Sealing ring with integrated cushioning means, end cap with sealing ring and pneumatic cylinder with end cap and sealing means

摘要

The ring has a damping buffer (1) for a piston (2) with a pressurizing medium, where the piston is axially reciprocated in a cylinder tube (3). A static seal (4) seals the cylinder tube opposite to a cover (5) that is connected to a front side of the cylinder tube. A dynamic seal (6) with a dynamically loaded sealing rim (7) is attached to a sealing surface (8) of a damping pin (9), which is connected with the piston, during intended use of the sealing ring. A flow-conductive connection port (10) connects axial front faces (11, 12) of the sealing ring.
