SEALING RING, CAP WITH SEALING RING AND PNEUMATIC CYLINDER WITH CAP AND SEALING RING

摘要

PROBLEM TO BE SOLVED: To provide a sealing ring of a simple structure with multiple functions.;SOLUTION: The sealing ring includes a damper (1) for a piston (2) capable of reciprocating in a cylinder pipe (3) in a shaft direction in which a pressure medium is workable, at least a static sealing (4) for sealing the cylinder pipe (3) for a cap connected to the end surface of the cylinder (3), a dynamic sealing (6) of a damping guiding rod (9) connected to the piston (2) having at least a sealing lip (7) which is dynamically required and capable of being connected with a surface (8) to seal and at least a connecting port (10) for connecting end surfaces (11, 12) mutually facing in the shaft direction of the sealing ring and making the end surfaces communicate with each other so as to make fluid flow wherein the damping guiding rod (9) can reciprocate together with the piston in the shaft direction in the case that the sealing ring is used as specified.;COPYRIGHT: (C)2008,JPO&INPIT
