Rotary compressor with vane slot pressure groove |
摘要 |
A rotary hermetic compressor including a compressor cylinder having a bore therein, and a sliding vane slidably disposed in a slot in the compressor wall. The vane extends into the bore of the cylinder for cooperating with a roller to divide the compression chamber into a suction chamber and a discharge chamber. A pressure groove is formed in the wall of the slot on the suction side of the vane. The pressure groove is supplied with oil by means of a passage directly connecting the groove with the oil sump whereby a bias force is applied to the vane to partially offset the unbalanced lateral force on the vane portion extending into the cylinder bore.
