Patent ID: 10519953

Abstract:
An upper piston of a rotary compressor is formed to satisfy 0.7×Hcy1/1000≤δro≤1.2×Hcy1/1000, Cro1≤0.1, Cro2≤0.1, and Cro1×Cro2≤0.007. Here, Cro1 indicates a length (mm) of an upper side piston outer circumferential chamfer portion in a height direction, and Cro2 indicates a length (mm) of the upper side piston outer circumferential chamfer portion in a normal line direction of a piston outer circumferential surface. An upper vane is formed to satisfy 0.7×Hcy1/1000≤δv≤1.2×Hcy1/1000, Cv1≤0.06, Cv2≤0.06, and Cv1×Cv2≤0.003. Here, Cv1 indicates a length (mm) of an upper side vane ridge line chamfer portion in a height direction, and Cv2 indicates a length (mm) of the upper side vane ridge line chamfer portion in a normal line direction of a vane tip end surface.
