  • Scroll fluid machine
    Patent number: 6210137
    Abstract: A scroll fluid machine having a lubrication pump provided between sliding contact surfaces of an orbiting scroll member and a thrust bearing in a casing. The pump has an orbiting member accommodating recess provided in the sliding contact surface of the thrust bearing. An orbiting member projects from the sliding contact surface of the orbiting scroll member into the recess. A slide plate defines a suction chamber and a discharge chamber in the recess. As the orbiting scroll member orbits, the orbiting member orbits in the recess, causing a lubricant contained in the casing to be sucked from a suction passage and delivered to the inside of a boss portion accommodating an orbiting bearing.
