<p>A scroll type refrigerant compressor is disclosed. The compressor includes a housing (10) and a pair of scroll (18,19) which is disposed within the interior of the housing (10). Each of the scrolls (18,19) has an end plate (181,191) and a spiral element (182,192) extending from one side surface of the end plate (181,191). Both spiral elements (182,192) interfit with one another at an angular and radial offset to make a plurality of line contacts to define at least one pair of sealed off fluid pockets. As orbital motion of one scrolls (19), the fluid pockets move toward center of the spiral element (182,192) with consequent reduction volume. The outer and inner side wall of spiral element (182,192) is formed by involute curves. The involute curve which forms the outer side wall of the spiral element starts from an arbitrary involute angle, and other involute curve which forms the inner side wall of spiral element starts from a involute point progressed of 180° from the arbitrary involute angle. The both starting point is connected by at least two arc shaped curve.</p> |
