Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/1995/027143
Kind Code:
A1
Abstract:
A scroll compressor (1) includes a fixed scroll member (73) and an orbiting scroll member (71). The scroll members each include a plate having an inboard surface and an outboard surface. A spiral involute or wrap (81 and 87) is formed on the inboard surface of each scroll member plate. The involutes mate to define suction zones at outer ends of the involutes and fluid pockets. The fixed scroll member (73) defines a fluid outlet (107) at the center of the involutes and two inlets positioned proximate the suction zones. At least two idler crank assemblies (109) are provided to maintain the phase relationship and running clearance between the scroll members. The idler crank assemblies each include two operatively connected cranks, one being in the fixed scroll and one being in the orbiting scroll. Ribs (131, 151, 153, 155, 157, 159, 161, 163 and 165) are formed on the surfaces of the plates to facilitate heat dissipation and to make the scroll members more rigid.
