新案登録請求の範囲第１項記載の回転圧縮機。[Claims for Utility Model Registration] 1. A cylindrical cylinder 3, a pair of cylinder heads 4, 4 covering both sides of the cylinder 3, a rotor 6 that rotates eccentrically within the cylinder 3, and an inner peripheral surface of the cylinder 3. The rotary compression system includes a blade 9 that partitions the space between the outer peripheral surface of the rotor 6 into a suction chamber 7 and a discharge chamber 8, and cools the helium gas used as the compressed gas by oil injection to the suction side. A rotary compressor characterized in that an oil release passage 18 is provided for communicating the discharge chamber 8 and the suction chamber 7 at a crank rotation angle θ of the rotor 6 of 330°±10°. 2. The oil relief passage 18 is formed in the cylinder 3, and the cylinder side passages 18a and 18b open to the discharge chamber 8 side and the suction chamber 7 side, and the crank rotation angle θ = 330 with respect to the cylinder side passages 18a and 18b.
The rotary compressor according to claim 1, which is a registered utility model, and comprises a blade side passage 18c formed in the blade 9 so as to communicate at an angle of ±10°. 3 Request for registration of a utility model in which the oil relief passage 18 is constituted by a notched groove formed on the inner circumferential surface of the cylinder 3 or the inner surface of the cylinder head 4 from a position at a crank rotation angle θ=330°±10° to the discharge chamber 8 side. The rotary compressor according to item 1.
