Реферат: SCROLL TYPE FLUID COMPRESSOR UNIT ABSTRACT In a scroll type fluid compressor having an orbiting scroll member and a fixed scroll member which form at least one pair of outer fluid pockets and a center pocket therebetween for fluid compression, the axial end surfaces of each spiral element of the scroll members have a groove along the spiral curve. At least one closed portion is located along the groove to block fluid flow in the groove. A seal element is loosely fitted in the groove. During operation the compressed fluid flows into the groove to urge the seal element against the end plate of the opposite scroll member so that the axial sealing between the spiral element and the end plate is assured without leakage of fluid along the groove. Also, the closed portion is located along the spiral element at the location where the line contact point where the outer fluid pockets and the central pocket merge to prevent back pressure changes from causing excessive wear of the seal element.
