録請求の範囲第１項記載の回転式圧縮機。[Scope of Claim for Utility Model Registration] (1) A crankshaft, a rolling piston rotatably fitted to the eccentric part of the crankshaft, a cylinder housing the rolling piston together with the eccentric part of the crankshaft, and the above-mentioned crankshaft. A lubricating oil passage provided on the shaft and supplying oil to the sliding part between the eccentric part and the rolling piston, and upper and lower bearings arranged above and below the cylinder to support the crankshaft and close the inside of the cylinder. In a rotary compressor, the rotary compressor is equipped with a discharge muffler that is fixed to an upper bearing and covers the upper end surface of the bearing, and the gas compressed in the cylinder is discharged through the discharge muffler via a valve device. A rotary compressor, characterized in that the gas passage inside the discharge muffler is provided with a constriction part, and the upper bearing is provided with a gas vent hole that communicates the constriction part with the circumferential portion of the rolling piston. (2) The rotary compressor according to claim 1 of the utility model registration claim, wherein the gas vent hole that communicates the contracted part of the gas passage in the discharge muffler with the inner peripheral part of the rolling piston has a tapered orifice. Machine.
