Claims

[Scope of utility model registration request]

A rotor that rotates by engaging with an eccentric portion of a drive shaft on the inner periphery of a cylinder housed in a case, and a blade that comes into contact with the outer periphery of the rotor to partition the refrigerant in the cylinder into a high pressure side and a low pressure side. In a rotary compressor equipped with a rotary compressor, a spring is provided, one end of which is connected to the blade, and the other end of which is fixed to the cylinder, and the spring is configured to apply a compressive force to the blade at low temperatures at the time of starting. A rotary compressor, characterized in that the blades are made of a shape memory alloy that exerts a tensile force on the blades at high temperatures during normal operation.
