Abstract
PURPOSE: To provide a closed type rotary compressor wherein lubrication to a cyclinder, upper and lower bearing plates, and a roller may be performed without difficulty by forming a passageway for lubricating oils so that it is open alternately to inside and outside the roller as it rotates.
CONSTITUTION: When a rotating roller 2 which is eccentric to the casing is in a certain first position, a passageway 7 through which refrigerants are injected is open to inside the roller. Since, at this moment, the pressure inside the roller is positive against that in an injection pipe 8 connected to the passageway 7, gas and lubricating oils are flown into the passageway 7. On the other hand, as the roller 2 is in a second position, the refrigerant passageway 7 is open to outside the roller 2, and a refrigerant staying in the injection pipe 8 on circulation cycles as well as the refrigerant and lubricating oil previously flown and still staying in the passageway 7 are forced into the compression room.
