Abstract

PURPOSE:To improve the suction efficiency by forming a cut part whose one side is opened onto the inner wall surface of a casing at the part close to the opened port part of the frame of a fixed scroll and forming a suction passage between the cut part and the inner wall surface. CONSTITUTION:A fixed scroll 2 is press-fitted into a casing 1, and a cut part 4b whose one side is opened onto the inner wall 1a of the casing 1 is formed at the part close to the opened port parts 2b and 2c of a frame 4. A suction passage 6 is formed between the cut part 4b and the inner wall surface 1a. Therefore, the dimension of the suction passage 6 can be secured sufficiently, and the suction efficiency can be improved.
