Title: ROTARY COMPRESSOR
Abstract:
The purpose of the present invention is to achieve a small highly reliable rotary compressor by prolonging the service life of a spring without enlarging the outer diameter of a cylinder. This rotary compressor is provided with: a coil spring (16) which is held in an elastically deformed state at a position away from the extension of a slot (19); and a lever (30) which is held, with a rotary shaft thereof disposed in a cylinder (11), so as to be able to swing about the rotary shaft, and transmits the restoring force from the elastic deformation of the coil spring (16) to a vane (14) as a force to cause the vane (14) to move toward a piston (13). When the center of the rotary shaft represents a fulcrum A, the position at which the lever (30) transmits the force to the vane (14) represents a point of load C, and the position where the lever receives the restoring force of the coil spring (16) represents a point of effort B, the distance from the fulcrum A to the point of load C is longer than the distance from the fulcrum A to the point of effort B.
