ABSTRACT:
A scroll type fluid displacement apparatus is disclosed in which a pair of scrolls interfit at an angular and radial offset, each scroll including a circular end plate and a spiral element. The axial end surface of each spiral element has a groove along its spiral curve and a seal element is fitted in the groove to seal off fluid pockets. A plurality of projections are formed in the bottom surface of the groove at a predetermined spacing. Then, when the scrolls are assembled in their interfitting positions, the seal element is partly compressed and deformed by the projections and the opposing circular end plate so that the seal element maintains contact with the facing end plate of the opposing scroll without the use of any axial force urging device.
