Claims

[Scope of utility model registration request]

A spiral lap is set upright on a disc-shaped end plate, a lap groove along the spiral is formed on the tip surface of the lap, and a sealing material is loosely fitted into the lap groove of fixed scrolls and oscillating scrolls. They are engaged with each other inside, and the oscillating scroll is caused to oscillate relative to the fixed scroll without rotating on its own axis.
Refrigerant gas is sucked in through the suction port that opens on the outer periphery of the fixed scroll, moves it to the center of the sealed space formed by the fixed scroll and the oscillating scroll while decreasing its volume, and opens at the center of the fixed scroll. In a scroll compressor that discharges compressed refrigerant gas from a discharge port and controls the injection capacity of oil/liquid refrigerant through a port provided on the end plate of a fixed scroll, the sealing material is used in the interference area between the sealing material and the port. A scroll compressor characterized by having a relief section.
