摘要： PROBLEM TO BE SOLVED: To provide a compressor pulley device capable of realizing the strength aspect of a tightening part of the compressor pulley device having a torque limiter mechanism even when the outside diameter of a shaft 2 of a compressor is reduced by incorporating a connection rod 10 formed of a material of the strength higher than that of an inner hub 22 between a cylindrical boss part 31 of the inner hub 22 rotated by an engine and the shaft 2 of a compressor.
SOLUTION: The outside diameter of the shaft 2 of the compressor is smaller than that of a conventional tightening shape by building a connection rod 10 formed of a material of the strength higher than that of the inner hub 22 between a cylindrical boss part 31 of the inner hub 22 and the shaft 2 of the compressor. Even if the outside diameter of the shaft 2 of the compressor becomes smaller, insufficiency of the strength of inner circumferential screw parts 35 and 44 with outer circumferential screw parts 43 and 3 can be solved for the tightening axial force of the inner circumferential screw parts 35 and 44 with the outer circumferential screw parts 43 and 3.

摘要： PROBLEM TO BE SOLVED: To provide a sealing device using a seal ring whose sealing performance is improved enough to practically prevent the permeability and leakage of pressurized CO2. SOLUTION: In the connection sections 13 and 16 of the two housings 12 and 15 surrounding a space in which pressurized carbon dioxide exists, in order to prevent the permeability and the leakage of the CO2, a ring-shaped seal ring 11 is used. In this case, the ring-shaped seal ring 11 has a long compressed shape in the direction of the joint between the connection sections 13 and 16 as if the shape of the cross section is originally elliptical in such a non-load state that any external force does not work and is compressed between the two housings 12 and 15, as a result, it becomes a seal ring 11' having a cross section of further compressed shape. Even if the CO2 tends to permeate the seal ring 11' for permeation, since the permeable distance and cross section area are longer and reduced than those in conventional O-rings respectively, the CO2 cannot permeate easily.

摘要： PROBLEM TO BE SOLVED: To stably supply lubricating oil to a scroll compressor by preventing the excessive increase of the amount of lubricating oil supplied to a compression mechanism without reducing the passage sectional area of a communication path so as to prevent the clogging of foreign objects in the communication path. SOLUTION: This compressor is constructed in such a manner that an oil passage 220 is formed to communicate an operation room V with an oil storage part 210, and the opening part 221 of the operation room V side of the oil passage 220 is opened to be communicated with, among a plurality of operation rooms V, one where an inner pressure P changes from a specified pressure Po lower than the pressure Pd of the oil storage part 210 to the pressure Pd or higher. Thus, since lubricating oil is supplied only to, among the plurality of operation rooms V, one where the pressure Pd is higher than the inner pressure P of the operation room V, the lubricating oil is intermittently supplied to a compression mechanism Cp. Therefore since the excessive supplying of lubricating oil is prevented without reducing the passage sectional area of the oil passage 220, the clogging of foreign objects in the oil passage 220 is prevented. Further, since lubricating oil is stably supplied to the compression mechanism Cp, the performance and reliability of the compressor are improved.

摘要： PROBLEM TO BE SOLVED: To mitigate a thrust force applied on a thrust bearing. SOLUTION: A first and second magnets 121 and 122 are buried to generate a repulsive force in an end plate part 114b between the end plate part 114b of a turning scroll 114 and a middle housing 107. Thus, since a thrust force applied on the turning scroll 114 is received by the repulsive force between the two magnets 121 and 122, the thrust force applied on a thrust bearing part is mitigated.

摘要： PROBLEM TO BE SOLVED: To reduce a shock at the time of starting a compressive mechanism by an engine. SOLUTION: A rotating magnetic field is generated around a rotor 403 by rotating a permanent magnet 401 together with a yoke 402 by an engine. Thereby, an induced current is generated in a wiring of the rotor 403, which is equivalent to secondary wiring of an induction motor, in an electric motor part 400 similarly to the induction motor, and a torque, by which the rotor 403 is rotatingly driven, is generated. Therefore, a shock at the time of starting can be reduced, because the electric motor part 400 operates as a magnetic coupling.

摘要： PROBLEM TO BE SOLVED: To reduce the manufacturing cost of a variable displacement swash plate type compressor by assuring a simple structure of the coupling portion between the lug part and the swash plate. SOLUTION: A shoe 10 which is slidably coupled to a spherical sliding part 8a formed on one end side of a piston 8 is held slidably relative to an oscillating plate 12, a third base line III which passes the center B of the spherical sliding part 8a and also passes the center A of coupling between the lug part 5a and the swash plate 4 passes the center B of the spherical sliding part 8a in a state in which the angle of inclination of the swash plate becomes maximum, and the angle θ formed by a first base line I which is parallel to the axial direction of the piston 8 and a second base line II which passes the center of the spherical sliding part 8a and is perpendicular to the swash plate 4 is substantially bisected. It is thereby possible to assure a simple structure of the coupling portion between the lug part and the swash plate while preventing displacement of the top dead point of the piston 8.

摘要： PROBLEM TO BE SOLVED: To prevent a bearing surface from being locally crushed, in a power transmission device wherein two rotors are concentrically arranged for transmitting rotating power and joined to each other by screwing and a bearing surface is formed in a conical shape. SOLUTION: In the power transmission device, a driven shaft 10 has a thread portion 14, a small diameter shaft portion 11, a large diameter shaft portion 12, and a truncated-cone-shaped tapered shaft portion 13, and the first rotor 20 has a center hole 25 including a tapered hole portion 27. When the first rotor 20 is threaded to the thread portion 14, the outer peripheral face of the tapered shaft portion 13 has close contact with a peripheral wall face 29 of the tapered hole portion 27. The peripheral wall face 29 consists of: a conical peripheral wall face 29a; and a curved peripheral wall face 29b smoothly ranging from the conical peripheral wall face 29a and curved and unfolded into a horn shape. The curved peripheral wall face 29b is arranged so that a gap is formed between a ridge line 15 formed on a boundary between the tapered shaft portion 13, and the large diameter shaft portion 12 and the peripheral wall face 29.
