Abstract: A compressor includes: an annular cylinder; a rotation shaft which is rotated by the motor; a piston which revolves along an inner circumferential surface of the cylinder, and forms a cylinder chamber on the inside of the cylinder; a vane which protrudes to the inside of the cylinder chamber from a vane groove provided in the cylinder, and divides the cylinder chamber into an inlet chamber and a compression chamber by abutting against the piston; and an injection hole which injects a liquid refrigerant to the inside of the compression chamber. The center of the injection hole is disposed to be within a fan-like range of which a center angle is equal to or less than 40° toward a side opposite to a connection position between the compressor housing and the inlet unit from a center line of the vane groove in the circumferential direction of the rotation shaft.

Abstract: At least three axis direction through-holes arranged at equal intervals in the circumferential direction are provided in a rotor laminated steel plate and a rotor end plate. The rotor laminated steel plate and the rotor end plate are fixed with three rivets for passing through the axis direction through-holes. A balance weight formed of one laminated metal plate is fixed to the one rotor end plate with two rivets of the three rivets.
