Claims

[Scope of utility model registration request]

The fixed scroll and the orbiting scroll, each having a spiral wrap erected on the inner surface of the end plate, are eccentrically arranged by a predetermined distance, and are engaged with each other with a phase shift by a predetermined angle, thereby achieving the above-mentioned spiral. A plurality of compression chambers are formed in point symmetry with respect to the center of the spiral, and the orbiting scroll is caused to revolve around the orbit while being prevented from rotating on its axis, so that the compression chamber is brought to the center of the spiral while decreasing its volume. In a scroll type compressor which is moved towards the end plate and communicated with a discharge port provided in the center of one of the end plates, the pair of spiral wraps are located at the corners of the tip and side surfaces of the inner end of the spiral wrap. A scroll type compressor characterized in that a chamfer is applied to constitute a counterhole for correcting pressure imbalance when the compression chamber communicates with the discharge port.
