<p>A scroll type fluid displacement compressor includes a housing (12), a pair of scrolls (13, 14) each comprising an end plate (131, 141) and scroll element (132, 142) projecting from one surface of the respective end plate. Both scroll elements are interfitted at an angular and radial offset to make a plurality of line contacts. A groove (134, 144) is formed on the end surface of each scroll element and a seal element (22, 23) is placed within each groove. The axial thickness of one seal element (22) is equal to the other seal element (23) is less than the distance between the bottom surface of the other groove and the end plate of the opposing scroll. Thus, one seal element is fixed in the axial direction and the other seal element is movable in the axial direction to effect a proper axial sealing of the scrolls while making it possible to more easily manufacture and assemble the scroll compressor.</p> |
