Abstract

The stuffing box ring has a piston rod (3) passing through it between the air-receiver chamber (4) and the crank chamber (5) The surface of the stuffing box ring (10-12) which slides along the piston rod when in operation has a hard, wear-resistant chrome o chrome-ceramic or galvanized coating. The ring has at least two segments peripherally adjacent and completing a ring. A spring ( encloses the ring's periphery and presses the ring against the piston rod.
