Claims

[Scope of utility model registration request]

It is equipped with an end plate, an orbiting scroll and a fixed scroll consisting of a spiral wrap standing upright on the end plate, and both scrolls are combined with each other with the wraps facing inward, and a closed working chamber formed by each lap and the end plate is at the center. In the scroll compressor, the orbiting scroll is rotated relative to the fixed scroll so that the volume decreases as the scroll moves in the direction, and after the volume decrease, the orbiting scroll is rotated relative to the fixed scroll such that the scroll is discharged from a discharge port provided in the fixed scroll. When moving toward the center, from the position communicating with the working chamber to the space immediately before the working chamber communicates with the discharge port, or until the working chamber passes through the minimum sealed chamber and is discharged from the discharge port. A scroll compressor characterized by having a passage that opens at a communicating position.
