Compressor

摘要

A compressor (100) includes a closed casing (101), a compression mechanism (120), a motor (130) and an oil separating member (17A). The oil separating member (17A) rotates together with a shaft (140). The oil separating member (17A) has a peripheral wall (173) and a bottom wall (175) that form a recess (171). An inlet of a discharge pipe (160) penetrating the closed casing (101) is located in the recess (171). A plurality of oil expelling ports (174) are provided in the peripheral wall (173) of the oil separating member (17A) so as to be scattered.

主权项

1. A compressor comprising:
a closed casing; a compression mechanism disposed in the closed casing so as to compress a working fluid and discharge the working fluid to an internal space of the closed casing; a motor disposed in the closed casing so as to drive the compression mechanism via a shaft; an oil separating member having a peripheral wall and a bottom wall that form a recess that opens, in a direction leading away from the shaft, with a size equal to or larger than a bottom face of the recess, the oil separating member being configured to rotate together with the shaft; and a discharge pipe penetrating the closed casing and having an inlet that opens toward the bottom wall in the recess, wherein the peripheral wall has a tapered shape extending in the axial direction of the shaft from a periphery of the bottom wall while expanding radially, a plurality of oil expelling ports are provided in the peripheral wall of the oil separating member so as to be distributed in a circumferential direction of the peripheral wall and an axial direction of the shaft, and the oil expelling ports each have an inner shape in which an opening decreases gradually in size from an inner side of the peripheral wall toward an outer side of the peripheral wall.
