<p>PURPOSE:To arbitrarily set the volume of a sealed space formed between fixed and turning scrolls by forming a cut part outside from the point where winding is performed by 360 deg. from the center edge part of one lap between the fixed and turning scrolls. CONSTITUTION:In a scroll type compressor, fixed and turning scrolls each of which is formed into an equal shape are meshed, setting each lap oppositely, and gas is compressed by the turn of the turning scroll. In this case, a cut part is formed outside from the point where winding is performed by 360 deg. from the center edge part of the lap onto one between the fixed and turning scrolls. For example, in the turning scroll 2, the turning lap 6 is erected on a disc- shaped turning mirror plate 4, and a cut part 12 penetrating through the turning lap 6 is formed at the position returning by 1/4 from the edge part on the outer peripheral part of the turning lap 6. Therefore, the volume of the sealed space formed between the fixed and turning scrolls can be set arbitrarily.</p> |
