Patent ID: 7717686

Claim:
A compressor comprising: a hermetic housing in which lubricating oil is stored in the bottom part thereof; a low stage-side rotary type compression mechanism provided in the hermetic housing and having a rotor, and a cylinder for holding a blade reciprocating with the rotation of the rotor while the tip end thereof is in contact with the rotor; a high stage-side scroll type compression mechanism provided in the hermetic housing to suck and compress refrigerant gas compressed by the low stage-side rotary type compression mechanism; a drive shaft connecting the low stage-side rotary type compression mechanism and the high stage-side scroll type compression mechanism to each other and having an oil feeding hole in the axial direction; an electric motor for driving the low stage-side rotary type compression mechanism and the high stage-side scroll type compression mechanism via the drive shaft; a lubrication pump for feeding the lubricating oil to the high stage-side scroll type compression mechanism via the oil feeding hole; and an oil feeding path for feeding the lubricating oil, which is fed to the high stage-side scroll type compression mechanism, is dripped toward the blade of the low stage-side rotary type compression mechanism.
