摘要： A scroll-type fluid machine includes an orbiting scroll member and a stationary scroll member each of which has an end plate and a spiral wrap protruding upright therefrom. The scroll members are assembled together such that their wraps mesh with each other. Closed spaces are defined by the wraps and end plates of both scroll members, and are progressively moved towards the center of the scroll members while decreasing their volumes in accordance with an orbiting movement of the orbiting scroll member. The edges of the projecting end of the wrap of each scroll member are chamfered. Also, steps are formed in conformity with the configuration of each spiral wrap on respective corners of the groove bottom between adjacent turns of the wrap. The chamfered edges of the projecting end of the wrap of each scroll member faces the steps on the groove bottom of the opposing scroll member, respectively, when the scroll members are assembled together.

摘要： A sealed scroll compressor comprises a scroll compressor section, an electric motor, a sealed container, an oil storage, a fixed and orbiting scroll members, and a wire mesh member for improvement of oil separation in refrigerant gas. A shell portion of said sealed container is lined annularly with the wire mesh member and the gas containing oil is adapted to flow downwardly along the wire mesh member. When the gas flows downwardly, the oil sticks to the wire mesh member and is separated from the gas. The oil collected on the wire mesh member drops down into the oil storage. The gas from which the oil is separated is, after that, discharged out of the compressor.

摘要： An improved scroll compressor comprises a fixed scroll and an orbiting scroll, as well as an Oldham's coupling which enables the orbiting scroll to have a orbital movement. The Oldham's ring of the Oldham's coupling is so formed that its sliding surfaces for counterpart members to slide thereon are formed by a base material containing silicon particles, while the surface of each silicon particle (remaining on the base material's surface serving as a slidable surface for counterpart members to slide thereon) is formed into a flat surface. In practice, a ratio of silicon portions formed into flat surfaces to an entire sliding area of the Oldham's coupling is in a range of 3% to 20%, preferably 5% to 15%. With the use of the scroll compressor of the present invention, it is possible to improve the wear resistance of the Oldham's ring of the Oldham's coupling and its counterpart members in the scroll compressor.
