Abstract (en)

[origin: EP3418569A1] An open-type refrigerant compressor (1) equipped with: a housing (2); an intake port (3); a compression mechanism (4) that compresses a refrigerant gas containing lubricating oil in the interior of the housing (2); a drive shaft (5) for driving the compression mechanism; a seal member (9) that is provided in a shaft hole (8) through which the drive shaft (5) protrudes to the outside from the housing (2), and that prevents refrigerant gas from leaking to the outside from the interior of the housing (2); a refrigerant supply passage (35) connecting the interior of the housing (2) and the seal member (9); and a refrigerant gas distribution unit (22) that distributes refrigerant gas, which has been introduced into the interior of the housing (2) from the intake port (3), to the refrigerant supply passage (35) side and the compression mechanism (4) side. The refrigerant gas distribution ratio of the refrigerant gas distributed by the refrigerant gas distribution unit (22) is set such that the amount distributed to the refrigerant supply passage (35) side is greater than the amount distributed to the compression mechanism (4) side.
