| An orbiting fluid machine has a feature that the speed of sliding movement is low, while vibrations are small, its performance is lowered when the rotational speed becomes high, and this problem is resolved by the following structure. A displacement fluid machine includes a displacer making an orbital motion within a casing into which a working fluid is drawn, thereby drawing and discharging the working fluid, in which an oil retaining mechanism or a seal mechanism is provided at each of opposite end surfaces of the displacer. This results that, axial gaps at the end surfaces of the displacer are effectively sealed so as to reduce a leakage loss, thereby achieving a high performance and a high reliability. | ||||||

| A high-performance and high-reliability scroll compressor which prevents seal property failure at seal necessary points, tooth tip contact, abnormal wear of an elastic body, fatigue failure, etc. A radially outward peripheral projection (4c) is formed on the full outer peripheral surface of a separation plate (4). The peripheral projection (4c) is set to an outer diameter reduced, relative to the inner diameter of the shell main body (9) before a shell lid (20) is sealed by welding, etc., by the dimension corresponding to the shrinkage amount of a shell main body (9). That is, before welding, a minute gap occurs between the outer peripheral surface of the peripheral projections (4c) and the inner peripheral surface of the shell main body (9). Then, the separation plate (4) is inserted into the shell main body (9) and further the separation plate (4) and a frame (3) are fixed. After this, when the shell main body (9) and the shell lid (20) are welded, because of shrinkage of the shell main body (9) after the welding, the outer peripheral surface of the peripheral projections (4c) of the separation plate (4) comes in tight contact with the inner peripheral surface of the shell main body (9), whereby the space is partitioned and sealed between a high pressure space (30) and a low pressure space (31). | ||||||
