摘要： A refrigerant compressor is provided that can be assembled easily and can quickly discharge lubricating oil that leaks from contact sliding parts of its mechanical seal so as to prevent the oil from turning into sludge around the stationary ring. In a refrigerant compressor in which a mechanical seal which shaft seals the inner side and the outer side of a housing is installed at a portion of the housing through which a rotating shaft penetrates, a mechanical seal comprises a stationary ring securely fastened to the inner circumferential surface of a boss portion, a rotary ring securely fastened to the outer circumferential surface of the rotating shaft to the inside of the stationary ring so as to face the stationary ring, whereby sliding contact is formed between sides of the stationary ring and the rotary ring. The inner circumferential surface of the boss portion to the outside of the stationary ring is provided with an inclined portion over the entire circumference or at least the gravitationally lower portion of the inner circumferential surface, which enlarges from the stationary ring side toward an oil discharge hole to the outside of the stationary ring.

摘要： A multi-stage compressor is provided that reliably prevents liquid compression in a higher stage compression mechanism and also prevents compression efficiency degradation resulting from overheating of injection refrigerant and from the lubricating oil being raised up together with the injection refrigerant. An injection circuit is branched into a plurality of circuits. A first circuit thereof is communicatively connected to an inside space of a closed housing that is at the same side as the higher stage compression mechanism with respect to an electric motor, and a second circuit is communicatively connected to an inside space of the closed housing that is opposite from the higher stage compression mechanism with respect to the electric motor. The first circuit and the second circuit are provided with a switching mechanism for switching the injection circuit to the first circuit or the second circuit according to the dryness of the injection refrigerant.
