Abstract (en)
A hermetic compressor (100) includes a closed casing (2), a compression mechanism (4), a motor (6), a discharge pipe (8), a first balance weight (18), a swirl flow generating portion (21), and a second balance weight (19). The motor (6) has a stator (14) and a rotor (15). A communication passage (20) is formed in the rotor (15) so as to introduce, into an upper space (7), a working fluid compressed in the compression mechanism (4) and discharged to a lower space (5) of the closed casing (2). A baffle plate (122) is provided as a discharge direction deflecting portion for causing the compressed working fluid to travel from the communication passage (20) to the upper space (7), while deflecting the working fluid in a direction inclined with respect to a direction parallel to a rotational axis O. The baffle plate (122) may be constituted by a part of the swirl flow generating portion (21).
