Abstract
A rotary compressor includes a casing, a compression mechanism housed in the casing and having a suction port, a joint pipe fixed to the casing and formed into a cylindrical shape, a suction pipe arranged inside the joint pipe and communicating with the suction port, and an accumulator including an outlet pipe connected to an inlet end of the suction pipe. A large diameter portion formed on an inlet side of the suction pipe is fixed to an inner peripheral surface of the joint pipe, and a small diameter portion formed on an outlet side of the suction pipe has a smaller outside diameter than the large diameter portion. The joint pipe is made of an iron-based material. A clearance is formed between an outer peripheral surface of the small diameter portion of the suction pipe and the inner peripheral surface of the joint pipe.

A rotary compressor comprising:
- a casing;
- a compression mechanism housed in the casing, the compression mechanism having a suction port;
- a joint pipe fixed to the casing, the joint pipe being formed into a cylindrical shape;
- a suction pipe arranged inside the joint pipe, the suction pipe communicating with the suction port of the compression mechanism;
- and
- an accumulator including an outlet pipe connected to an inlet end of the suction pipe,
- the suction pipe having
- a large diameter portion formed on an inlet side of the suction pipe, the large diameter portion being fixed to an inner peripheral surface of the joint pipe, and
- a small diameter portion formed on an outlet side of the suction pipe, the small diameter portion having a smaller outside diameter than the large diameter portion,
- the joint pipe being made of an iron-based material,
- a clearance being formed between an outer peripheral surface of the small diameter portion of the suction pipe and the inner peripheral surface of the joint pipe, and
- in a vertical sectional view, a total length of a width of an upper side of the clearance and a width of a lower side of the clearance being smaller than an inside diameter of the small diameter portion of the suction port.
