転式圧縮機。 A cylinder installed in a sealed case with lubricating oil stored at the bottom, a main frame body and an auxiliary frame body attached to both sides of this cylinder, and a cylinder supported by both frames with its axis arranged horizontally. The refrigerant is sucked and compressed by a crankshaft, a roller that is fitted onto the crankshaft and rotates eccentrically within the cylinder, and a vane that moves back and forth in contact with the outer peripheral surface of the roller. A vane chamber having an inlet and an outlet for lubricating oil is provided at the back of the crankshaft, and a semi-cylindrical notch is provided at the end of the crankshaft, and the outlet of the vane chamber and the notch of the crankshaft are communicated from the end face side of the shaft. A refueling passage is provided, and the cutout communicates with the refueling passage when the vane moves in a direction to reduce the volume of the vane chamber in synchronization with the movement of the vane, and communicates with the oil supply passage when the vane moves in a direction to expand the volume of the vane chamber. A horizontal rotary compressor characterized in that a passage is closed by a half-moon-shaped end face of a crankshaft.
