A flat plate hydrodynamic thrust bearing for orbiting machinery and scroll-type apparatus embodying the thrust bearing are disclosed. The thrust bearing exerts an axial force on the orbiting scroll member to ensure efficient radial sealing of the scroll assembly; and one of the contacting surfaces of the bearing and or of the orbiting scroll member, serving as a journal, has a plurality of intersecting groovings to ensure continuous lubrication of the surfaces. The scroll apparatus is particularly suited for incorporation in a closed cycle refrigeration system wherein minimum wear over extended periods and quiet and reliable operation are required. |
