SCROLL COMPRESSOR

PURPOSE:To equalize the contact to a counterpart side end plate of one side lap tip by forming a recessed part with a depth corresponding to this heat expansion on the lap tip part in at least one end central part among fixed and turning scrolls meshed with each other. CONSTITUTION:A pair of scrolls 1, 2 with a lap 4 erected consisting of an involute curve, etc., on an end plate 3 respectively are meshed with each other. Among both scrolls 1, 2, the one is fixed and the other is turned so as not to rotate. In this case, among both scrolls 1, 2, a recessed part 11 with a depth corresponding to this heat expansion is formed on the lap 4 tip part in at least one side central part. A part with 0.5mm or less of a lap 4 height direction size in the tip part of the lap 4 is formed by a material easy to wear, for example ethylene.teflon copolymer, etc. Accordingly, the contact of the lap 4 tip of scroll central part with the opposite side end plate 3 caused by heat expansion is eliminated and any seizure and wear are prevented.
