Abstract:
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.
