Claims

[Scope of utility model registration request]

(1) A crescent-shaped compression space formed by meshing a fixed scroll and an orbiting scroll is moved continuously while contracting the orbiting scroll toward the center of the spiral, and the compressed material is compressed in the compression space. In a scroll compressor that discharges compressed fluid from a discharge passage formed in the center of a fixed scroll, the discharge port is formed in the center of the fixed scroll, and a groove whose diameter is enlarged from this on the discharge side of the discharge port. 1. A scroll compressor, characterized in that a shaped storage section is formed, and a closing valve mechanism for opening and closing the discharge port is housed in the storage section.

(2) The opening/closing valve mechanism includes a float valve plate that opens and closes the discharge port by floating it with the fluid discharged from the valve mechanism, and a stop valve plate that guides the valve plate while regulating the upward movement of the valve plate within a predetermined range. The stop valve plate is flatly attached along the upper edge of the opening of the storage portion, and the float valve plate is interposed between the stop valve plate and the discharge port. Scroll type compressor according to scope 1.
