RECIPROCAL PISTON TYPE COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To secure lubrication and cooling of each sliding part by making it difficult to take lubricating oil reserved in a compressor out to an outside refrigerant circuit. SOLUTION: A discharge chamber 43 is partitioned and formed in a ring shape on the outer peripheral side of the inside of a rear housing 13, and regulation ribs 69 to regulate flow of a liquid refrigerant by making a pair along between a partition wall 70 of its lower part and an outer peripheral wall 71. A plural number of collision walls 72. 73 are alternately erected from the partition wall 70 and the outer peripheral wall 71 on a lower part of the discharge chamber 43 and on a passage between each of discharge valve mechanisms 49 and a discharge passage 44. Additionally, the adjacent collision walls 72, 73 are formed so that their head ends are lapped in the flowing direction of refrigerant gas.
