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： 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 scroll-type fluid machine having an orbiting scroll member and a stationary scroll member each having an end plate and a spiral wrap of at least two turns protruding upright from one of the sides of the end plates. The orbiting scroll member has a back pressure chamber formed on the back side thereof and communicating with the compression spaces of the fluid machine through pressure equalizing ports formed in the orbiting scroll member, so that the pressure of the fluid under compression is introduced to the back pressure chamber to produce an axial thrusting force for pressing the orbiting scroll member towards the stationary scroll member. The positions of the pressure equalizing ports in terms of the wrap angle .lambda. of the wraps are selected to meet the following condition:.lambda.d>.lambda.>.lambda.d-2.pi.,where, .lambda.d represents the wrap angle of the wraps when the volume of the compression spaces is minimized. The equalizing ports are positioned at .lambda. and .lambda.+2 .pi..

摘要： A scroll compressor including a stationary scroll and an orbiting scroll, with an intermediate pressure chamber being defined on a back side of the orbiting scroll member and being in communication with a pressure chamber through a communication hole to produce a force for pressing the orbiting scroll against the stationary scroll. Oil in an oil sink is supplied to sliding portions by a differential pressure between a pressure in the air tight container and a pressure in the intermediate pressure chamber. A valve is provided for switching the connection of the intermediate pressure chamber to a higher intermediate pressure side or to a lower intermediate pressure side of the compressor. The valve is constructed such that the intermediate pressure chamber is connected to the lower intermediate pressure side of the compressor when a discharge pressure of the compressor is lower than a certain value and connected to the higher intermediate pressure side of the compressor when the discharge pressure is higher than a certain value so that a proper oil supply pressure is maintained over a wide operational range.

摘要： A scroll fluid apparatus including a fixed scroll member and an orbiting scroll member each having an end plate and a wrap, the two scroll members being maintained in meshing engagement with each other with the respective wraps facing inwardly to allow the orbiting scroll member to move in orbiting movement with respect to the fixed scroll member without rotating on its own axis. The fixed scroll member is formed with a discharge port at its central portion and a suction port at its outer peripheral surface to draw a gas by suction through the suction port and allow same to flow in a sealed space defined between the two scroll members and reducing its space during operation to thereby compress the gas and discharge the compressed gas through the discharge port. A clearance is defined between an outer peripheral surface of the end plate of the orbiting scroll member and a wall facing the outer peripheral surface and successively changing its volume as the orbiting scroll member moves in orbiting movement, and at least one pressure relieving space is provided to communicate with the clearance for conveniently discharging a fluid from the clearance to avoid compression of the fluid.
