Claims

[Scope of utility model registration request]

A fixed scroll fixed in an airtight container and an oscillating scroll supported on an eccentric shaft of a crankshaft rotating in an airtight container are opposed to each other by engaging each other's spiral plate teeth, and the rotation of the eccentric shaft is made In a scroll type compressor that compresses gas in a compression chamber formed between the teeth by swinging the oscillating scroll through an Oldham joint, the Oldham joint is arranged orthogonally to a small-diameter disk and both the front and back surfaces thereof. and a pair of protrusions protruding from each other, and the Oldham joint is interposed between opposing surfaces of the toothless portions provided at the center of each of the scrolls, and both protrusions are provided on each of the opposing surfaces. A compressed gas discharge pipe is provided which is slidably fitted into the concave groove and which passes through the fixed scroll along the toothless portion of the fixed scroll to communicate the compression chamber with the outside of the closed container. scroll type compressor.
