  • Publication number: 20150093275
    Abstract: To fasten an auxiliary crank for prevention of autorotation of an orbiting scroll to a compressor-casing side bearing in a scroll compressor, a tool must access from a motor side to a compressor casing so as to fasten the auxiliary crank to the compressor-casing side bearing. Therefore, fastening between the auxiliary crank and the bearing cannot be made after a motor section and a compressor body are fastened together. This necessitates the steps of: separating the compressor body from the motor section; fastening the auxiliary crank to the compressor casing; and then fastening the compressor body and the motor section together. A compressor-motor integrated scroll compressor cannot be assembled in sequential steps, entailing increased assembly costs and lowered maintenability. A plurality of notches or holes is formed on a motor housing or the compressor casing.

  • Patent number: 8858203
    Abstract: In a scroll air compressor as a scroll fluid machine capable of being downsized with an increased cooling effect, cooling air entering through a fixed inlet of a fixed cooling passage provided at the rear of a fixed scroll, and an orbiting inlet of an orbiting cooling passage provided at the rear of an orbiting scroll, is allowed to flow out of an fixed outlet and an orbiting outlet, respectively. Thereafter, the cooling air is guided to an outer periphery of the other end of the casing through a side duct and a guide duct, and then sucked into an inner peripheral side of a centrifugal fan to be discharged outwardly from an exhaust port provided in a fan cover.

  • Patent number: 8628313
    Abstract: A scroll fluid machine that is capable of preventing a power loss and enhancing the degree of hermeticity of compression chambers. A plurality of outer peripheral projections are formed on an outer peripheral surface of a wrap portion of each scroll. An outer peripheral coating layer is formed on an outer peripheral surface of a wrap portion of a fixed scroll, and an inner peripheral coating layer is formed on an inner peripheral surface of the wrap portion. Each of the coating layers comprises: contact portions that make contact with the mating wrap portion; and non-contact portions that do not make contact with the mating wrap portion. In this way, the degree of hermeticity of the compression chambers can be enhanced by the contact portions, and power loss can be prevented by the non-contact portions.

  • Publication number: 20080159894
    Abstract: A gap between opposing wrap portions is narrowed to increase compression efficiency, and an amount of machining time is reduced to thereby increase productivity. A plurality of proximate portions 8 are formed, at spacings in a spiral direction, on an outer peripheral surface 3B of a wrap portion 3 of a fixed scroll 1. Flat surfaces 8A are used to connect adjacent proximate portions 8. Similarly, a plurality of proximate portions 14 are formed, at spacings in the spiral direction, on an outer peripheral surface 13B of a wrap portion 13 of an orbiting scroll 11. Flat surfaces 14A are used to connect adjacent proximate portions 14. In this way, the outer peripheral surfaces 3B and 13B of the wrap portions 3 and 13 can be formed in polyangular shapes, so as to reduce a gap between the wrap portions 3 and 13 and simplify the shapes. As a result, an amount of machining time can be reduced.
