Claims

[Scope of utility model registration request]

In a scroll compressor, an orbiting scroll and a fixed scroll each having a lap formed in a spiral shape are provided so that the laps are engaged with each other, and the orbiting scroll is rotated while maintaining a certain eccentric distance with respect to the fixed scroll. A suction groove is formed on the inner circumferential surface of the fixed scroll facing the outermost lap part of the wrap so that a space is always formed between the outermost lap parts, and a suction groove is sucked into the suction groove to suck the compressed fluid. ±4 around the tangential direction of the winding end of the suction groove above.
A scroll compressor characterized in that it is located between an angle of 5 degrees.
