摘要： A coating solution that contains 10 to 20% by weight of epoxy resin serving as a thermosetting resin, 20 to 30% by weight of MoS2, and 5 to 10% by weight of graphite, with a remainder thereof constituted by an organic solvent, is sprayed onto a wrap portion side face of an orbiting scroll from a spray nozzle . While spraying the coating solution, the orbiting scroll is rotated on a rotating table and the spray nozzle is moved along a rectilinear movement path toward a radial direction outer side of the orbiting scroll while maintaining an attitude thereof from the start of the spraying process. After applying the coating solution, the coating solution is dried by baking, whereupon a break-in operation is performed. As a result, an elastic coating is formed at a coating thickness that enables elastic deformation in accordance with a clearance between the wrap portion side faces.

摘要： A scroll fluid machine includes a compressor body having a first scroll and a second scroll which form a compression chamber, a cover forming an air guiding space by covers at least a portion of the compressor body, and a blower fan supplying cooling air to at least one of the first scroll and the second scroll. A portion of the cooling air is supercharged into the intake port via the air guiding space whereby satisfactory compression efficiency is achieved with a simple configuration.

摘要： A scroll fluid machine includes fixed and orbiting scrolls which form a compression chamber; a land which divides the compression chamber into first-stage and second-stage compression chambers; a wrap groove formed in a spiral shape along a tip of a fixed wrap of the fixed scroll; an intermediate groove formed in the land; a seal member; and an intermediate seal member. The land includes a first-stage outlet communicating with the first-stage compression chamber and a second-stage inlet communicating with the second-stage compression chamber. The wrap groove includes an outer peripheral wrap groove adjacent to the land on a radially outward side and an inner peripheral wrap groove adjacent to the land on a radially inward side. The intermediate groove is in communication with the outer and inner peripheral wrap grooves. The seal member is fitted in the wrap groove except the outer and inner wrap grooves. The intermediate seal member includes an outer peripheral seal portion fitted in the outer peripheral wrap groove, an inner peripheral seal portion fitted in the inner peripheral wrap groove, and the intermediate seal portion fitted in the intermediate groove and connected to the outer and inner peripheral seal portions.

摘要： An orbiting scroll is fixed on a rotating table and rotated about a spiral center. A spray nozzle is positioned in the spiral center or at an outside end of the orbiting scroll and caused to discharge a coating toward a side face of a wrap portion. The spray nozzle is moved along a straight line in a radial direction while discharging the coating. When a spraying start position is set as the spiral center, a rotation angle speed of the orbiting scroll is gradually reduced in accordance with the movement of the spray nozzle. When the spraying start point is set as the outside end, the rotation angle speed of the orbiting scroll is gradually increased in accordance with the movement of the spray nozzle. As a result, the coating can be applied to the wrap portion side face evenly.

摘要： A disc-like spacer arranged below a first roller bearing rotatably supporting a driven crankshaft that forms an anti-rotation system is formed with a plurality of notches in the circumferential direction. A spot face is provided to face the outer circumferential surface of the spacer, and communication holes and are drilled on the outer circumferential side of the spot face to extend in the axial direction of the scroll. Also formed is a communication hole communicating the communication hole with the first roller bearing via the notches. A grease nipple is mounted to the communication hole. To replenish grease, the fixed scroll is removed from the housing such that the orbiting scroll is exposed, and grease is injected from the grease nipple into the first roller bearing with a grease gun.
