HERMETIC COMPRESSOR

摘要

Provided is a hermetic compressor comprising a hermetic housing (10), a motor (4) built in the hermetic housing, and a compression mechanism (3) that is provided above the motor and is driven by the motor through a driving shaft (7). The hermetic compressor is configured to feed lubricant oil that fills an oil reservoir (12) in a bottom portion of the hermetic housing (10), to a desired lubrication site of the compression mechanism through an oil feed pump (11) and an oil feed hole (14) provided in the driving shaft; and return the oil that has been used for lubrication of the site, to the oil reservoir (12) through an oil discharge hole (45) provided in a support member (31) of the compression mechanism (3) and an oil discharge pipe (47,47A,47B), wherein the oil discharge pipe has a lower end that is opened at a position below a stator coil end (5A) of the motor (4) and above an upper end of a stator (5) so as to be opposed to a stator cut (5B) provided in an outer periphery of the stator, the oil discharge pipe (47,47A,47B) has a lower portion curved toward the outer periphery of the stator, and the oil discharge pipe has an outer diameter (D) that is set to be larger than a radial width (L) of the stator cut (5B).
