PISTON COMPRESSOR FOR THE OILFREE COMPRESSION OF A GAS

The piston compressor exhibits at least one piston (7) which is supported to be freefloating and connected via a piston rod (6) to a crosshead (5). The piston rod slides in a guide bearing (8) next to the crosshead in a gland (11) next to the cylinder. A ring (15) of porous material is arranged on t...

More Information
Summary:The piston compressor exhibits at least one piston (7) which is supported to be freefloating and connected via a piston rod (6) to a crosshead (5). The piston rod slides in a guide bearing (8) next to the crosshead in a gland (11) next to the cylinder. A ring (15) of porous material is arranged on the piston rod (6) between the guide bearing (8) and the gland (11). The ring (15) exhibits a circumferential groove which is intended for receiving a tubular spring and the depth of which-measured from the outside transversely to the longitudinal axis (6') of the piston rod-is at least as great as the outer diameter of one turn of the tubular spring.
