ABSTRACT:
A device to ensure tightness without friction and thus as reduced as possible clearance at the high pressure end of the screw. At the high pressure side of the screw, the bearing housing of the screw comprises a metal ring which is different from the metal of the screw ring and has a higher coefficient of expansion. This ring fills up a circular recess machined at the end of the screw. This device ensures an almost perfect leak-tightness in the case of compressors, or oil free expansion machines or high pressure pumps.
