  • Fluid machine with resin-coated scroll members
    Patent number: 4802831
    Abstract: A compressor has stationary and orbiting scroll members formed thereon with spiral wraps engaged with each other to define compression chambers which, when the orbiting scroll member is moved relative to the stationary scroll member, are radially inwardly moved while decreasing their volumes. Each scroll member is composed of a metallic base scroll member having a spiral wrap formed on one side and a coating layer of a resin compound formed on the said side of the scroll member, including the surfaces of the wrap. The coating layer is molded by placing the base scroll member in a mold cavity with a space left between the said side of the base scroll member and a mold part and by injecting the resin compound into the space.
