<p>A scroll type fluid displacement apparatus with an axial sealing mechanism is disclosed. The compressor includes a pair of scrolls (22,23) each of which comprises an end plate (221,231) and a spiral element (222,232) axially extending from one end surface of the respective end plate. A groove (225,233) is formed in the axial end surface of the spiral element along a spiral curve and has a uniform depth. A seal element (33) is disposed within each of the grooves to secure the axial sealing of fluid pockets defined by the scrolls. The axial thickness (t,) of central or inner portion of the seal element is formed smaller than the depth (T) of the groove and the axial thickness (t2) of outer portion of the seal element is formed larger than the depth (T) of the groove.</p> |
