摘要

The arrangement for guiding and sealing a reciprocating piston rod in a bore comprises a groove (9) whose shoulder (12) nearest to the piston has a slightly smaller diameter than the outer diameter of the glide ring (11) of the sealing ring unit (10, 11). The shoulder (12) is joined to a bore accommodating a guide sleeve (16) via a conical transition section (14).
