Abstract
A scroll-type compressor having a fixed scroll and a revolving scroll, wherein a portion of either the end plate of the fixed scroll or the top plate above the fixed scroll has annular grooves formed therein, allowing elastic deformation of either the end plate or the top plate in a thrust direction, thus preventing gaps between the spiral wraps of both scrolls.
