Claims

[Scope of utility model registration request]

In a scroll type compressor in which the orbiting scroll is meshed with the fixed scroll so that the side wall surfaces of each spiral body are in contact with each other at four places, the orbiting scroll is configured to revolve around the fixed scroll without rotating on its axis. One or more labyrinth seal grooves are provided extending along the spiral end surface that abuts the mating scroll end plate of the spiral body, and each of the labyrinth seal grooves is partitioned at appropriate intervals by a plurality of weirs. Scroll compressor.
