摘要： PURPOSE:To prevent drop of the oil level in a machine chamber by boring a gas hole in a rotor of a motor, providing the shaft with a through hole leading from the compressor side to the motor side, and installing a disc at the end of rotor on its side opposite to the compressor. CONSTITUTION:In a horizontal type rotary compressor machine, wherein a motor 2 and a compressor 4 in direct coupling with its shaft 3 are accommodated in an enclosure case 1, a disc 9 is fixed to that of the end faces of motor 2 which is mating with the motor side-chamber 8 of rotor 6 in which the shaft 3 is fitted, and a gas hole 10 is formed penetrating the rotor 6. In this compressor 4, that of the two chambers partitioned by the motor 2 which is situated nearer the compressor 4 is further partitioned into two chambers 16, 17, among which the one 16 nearer the compressor is in communication with the motor side-chamber 8 through a through hole 18, which is formed in the shaft 3. The oil in the mixture of oil and refrigerant gas sucked into this through hole 18 is advanced in the discharge direction by a vane pump 22 and by centrifugal force and fed to a crank chamber via an oil supply hole 23.
