CLOSED TYPE MULTI-CYLINDER ROTARY COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable closed type multi-cylinder rotary compressor capable of uniformly feeding lubricating oil to two compression mechanism parts and sufficiently feeding lubricating oil to a main bearing with a simple structure. SOLUTION: An oil hole 21 is provided in the axial direction of a crankshaft 16, and a spiral oil vane 22 is installed in the oil hole 21 so as to partition the oil hole 21. Chambers 23a and 23b separated from each other through the oil vane 22 and the outer peripheral surfaces of two eccentric shaft parts 15a and 15b communicate with each other through communication holes 24a and 24b, respectively.
