Kind Code:
A
Abstract:
To provide a scroll fluid machine which can minimizes the leakage of fluid from a chip clearance even when the scroll fluid machine has an inclined part.SOLUTION: A scroll fluid machine comprises: inner peripheral side wall-body flat parts 3b2, 5b2 arranged on innermost peripheral parts of wall bodies 3b, 5b; an inner peripheral side end-plate flat part 3a2 arranged on innermost peripheral parts of end plates 3a, 5a and corresponding to the inner peripheral side wall-body flat plates 3b2, 5b2; wall-body inclined parts 3b1, 5b1 with wall-body heights thereof continuously increasing; an end-plate inclined part 3a1 whose tooth bottom face opposite a tooth tip of the wall-body inclination part 5b1 is inclined according to inclination of the wall-body inclined part 5b1; a chip seal which makes contact with an opposite tooth bottom to seal fluid; and a discharge port 3c which is formed in a center of the end plates 3a, 5a and through which compressed high-pressure refrigerant circulates. The inner peripheral side wall-body flat parts 3b2, 5b2 and the inner peripheral side end-plate flat part 3a2 are arranged over a range of a first compression chamber 12 which is formed on the innermost periphery at a timing when they communicate with the discharge port 3c.SELECTED DRAWING: Figure 4
