Abstract: PROBLEM TO BE SOLVED: To provide a scroll fluid machine, reducing a sliding loss between a thrust face of a fixed scroll and a sliding face of a swirl end plate to enhance efficiency and reliability.
SOLUTION: Since a notch 21 is formed to an outer peripheral part where a swirl spiral blade 5 of the swirl end plate 6 is not formed, an area in contact with the thrust face of the fixed scroll of the swirl end plate 6 can be decreased to reduce an unnecessary sliding face 19. Therefore, the sliding loss can be reduced, and progress of wear on the sliding face can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll compressor, in which sealability of a cock installed to a swirl scroll is improved and a cork made from an inexpensive material can be used therefor. SOLUTION: The cock 13 is installed on an outer peripheral side of a swirl end plate 7b of a communicating hole 16, at a position closer to the outer peripheral side than a part in which a swirl spiral blade 7a of the swirl end plate 7b is formed. Therefore, since temperature rise is small on a side closer to the outer periphery than the part in which the swirl spiral blade 7a of the swirl end plate 7b is formed, little deformation is caused by heat expansion of the swirl end plate 7b and the cock 13 near the part provided with a cock mounting part 24 even in operation, and thereby a screw part is not loosened and sealability of a bearing surface 23 is not degraded.

Abstract: PROBLEM TO BE SOLVED: To handle a coolant 27 and an oil 6 while that are virtually constrained, and to enable a gas which has been sufficiently separated into vapor and liquid to be discharged from an external discharge pipe 39.
SOLUTION: A coolant gas 27 containing an oil is discharged from a discharge port 18, passes through a rotor passage 36, and subsequently passes through a stator passage 37. Then, the coolant gas 27, after coming out of a stator upper section chamber 38 at outside circumference of a connection chamber 34, is discharged to the outside of the sealed vessel 1 passing through an external discharge pipe 39 provided at a portion higher than the location of the stator upper section chamber 38 of a sealed vessel 1. Then, the oil 6 is made to be hard to come up the inner wall surface of the sealed vessel 1 by providing a concave and convex 5 processing on the inner wall surface of the sealed vessel 1, and is prevented from being discharged to the outside of the sealed vessel 1, so that oil 6 adhered to an inner wall surface of the sealed vessel 1 may not come up the inner wall surface of the sealed vessel 1, and may not be discharged to the outside of the sealed vessel 1 as it is. As a result, only the coolant 27 is discharged to the outside of the sealed vessel 1 thereby subjecting the oil to vapor liquid separation with good efficiency.

Abstract: PROBLEM TO BE SOLVED: To provide a rotation prevention mechanism having high reliability and capable of being miniaturized, and to provide a scroll compressor using the same.SOLUTION: Two pairs of key parts 13 and two pairs of key parts 14 are provided on one surface and the other surface of an Oldham's ring 12, respectively. Two pairs of key groove parts 15 into which the two pairs of key parts 13 at the one surface side are slidably fitted, respectively, are provided on an orbiting scroll 9. Two pairs of key groove parts 16 into which the two pairs of key parts 14 at the other surface side are slidably fitted, respectively, are provided on a bearing member 6. Accordingly, because the key groove parts respectively provided on the orbiting scroll and the bearing member can be made long, an orbiting radius can be designed to be large. Furthermore, because two pairs of key parts are provided for each, a surface pressure acting on each key part can be suppressed low, and a small size and high reliability are obtained.

Abstract: PROBLEM TO BE SOLVED: To solve a problem that, because a bush does not rotate with respect to an eccentric shaft, the bush near in the maximum eccentric direction partially contacts with an eccentric shaft bearing.SOLUTION: A slide ring 30 is fitted over the outer periphery of an eccentric shaft 14a with a small gap. The slide ring 30 slides without being fixed in one direction with respect to the eccentric shaft 14a. Because a position supported by an eccentric shaft bearing 43 moves over the entire periphery without being partially fixed, so that the position is not locally supported by the eccentric bearing 43. Accordingly, reliability is improved.

Abstract: PROBLEM TO BE SOLVED: To provide a compressor that does not deteriorate performance and reliability even under such severe working conditions that it is mounted on an engine.SOLUTION: The compressor includes: a stepped part 3c provided in the axial direction of an inner periphery of a body casing 3; a C-type groove 3b provided on the inner periphery of the body casing 3; and a C-type annular member 17. One end in the axial direction of a stator 5a is abutted to the stepped part 3c, the C-type annular member 17 is abutted to the other end in the axial direction of the stator 5a, and the C-type annular member 17 is inserted to the C-type groove 3b. As a result, increase of a temperature around the compressor causes a container to be subjected to thermal expansion, and further, even if vibration of the engine causes an excessive load to act on an electric motor, the stator 5a is fixed on the body casing 3 by the C-type annular member 17, and thereby displacement of the electric motor is prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a scroll fluid machine improving efficiency and reliability by reducing sliding loss between a thrust surface of a fixed scroll and a sliding surface of a turning end plate.
SOLUTION: A surface touching the thrust surface of the fixed scroll of the turning end plate 6 has a shape offsetting to an outside by seal length a from an outside envelop of a locus drawn by a fixed scroll blade formed on the thrust surface of the fixed scroll in a view from a turning scroll 7 side when the turning scroll 7 turns. Consequently, since the area touching the thrust surface of the fixed scroll of the turning end plate 6 is made small and unnecessary sliding surface 19 is made small, sliding loss is reduced and progress of wear of the sliding surface is inhibited.

Abstract: PROBLEM TO BE SOLVED: To provide a hermetic compressor enabling welding evenly transferring heat in welding during barrel shell molding with respect to a cylindrical barrel shell attached to a motor and a compression mechanism.
SOLUTION: A steel plate used as the barrel shell of a hermetic vessel is cut in such a manner that a burr direction is set inside when the steel plate is formed in the barrel shell, and then the plate is formed in a cylindrical shape. After that, an abutting joint part is welded to complete the barrel shell. Consequently, welding heat is evenly transferred, and the hermetic vessel excellent in pressure resistance without the irregularity of welding can be obtained.

Abstract: PROBLEM TO BE SOLVED: To solve such a problem that, in a fluid machine requiring efficiency and durability, the improvement of seizure resistance and wear resistance and the reduction of sliding loss at the sliding part thereof have been required as subjects, e.g., in a scroll type compressor using carbon dioxide as a refrigerant, these subjects have been produced at the sliding part of a scroll composed of an aluminum alloy.
SOLUTION: The fine powder of a solid lubricant is collided against the sliding face of a sliding member (movable scroll 3) essentially consisting of aluminum, so as to form a solid lubricating film, and thereafter, anodization treatment is performed, thus a lubricating oxide film layer comprising the solid lubricant is formed on the surface layer of the sliding face. In this way, the sliding member capable of achieving the improvement of seizure resistance and wear resistance and the reduction of sliding loss, and the fluid machine having high reliability and efficiency can be provided.
