<p><P>PROBLEM TO BE SOLVED: To provide a scroll type fluid machine capable of reducing a space formed between two adjacent surfaces during thermal expansion, concerning the outer surface and inner surface of a rocking scroll lap and the outer surface and inner surface of a fixed scroll lap. <P>SOLUTION: In the scroll type fluid machine 1, a compression chamber or an expansion chamber is constituted between a rocking scroll and a fixed scroll by rocking the rocking scroll 2 with respect to the fixed scroll 3, and the rocking scroll and the fixed scroll have a rocking mirror plate 20 and a fixed mirror plate 30, and a rocking lap 21 and a fixed lap 31 projecting from the mirror plates 20, 30, respectively. The fixed lap 31 is inclined to the outer circumferential side Se. The thickness of the fixed lap 31 is increased from the mirror plate side Sp to the fore end side Sd. The ratio of the thickness 31Td on the fore end side to the thickness 31Tp on the mirror plate side is increased along one direction to the outer circumferential side Se from the inner circumferential side Si of the fixed lap 31. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
