<p>A scroll compressor having a housing (10) containing an orbiting scroll (12) and a non-orbiting scroll (14) each having a base (16, 18) formed with a free side (17, 19) and a compression side (20, 22) and having an involute (24, 26) extending generally normally from the compression side, each involute having a radially outer inlet end (32, 34) and a radially inner discharge end (36, 38), the orbiting scroll having special bearing structure for eliminating the laterally directed tipping forces which are generally experienced by the orbiting scroll of conventional scroll compressors, the bearing structure having a bearing hub (42) integral with the discharge end of the orbiting scroll involute, the hub having a cylindrical bore (44) oriented substantially normal to the compression side of the orbiting scroll for rotatably receiving an eccentric shaft section (52) of a compressor crankshaft (48), bearing means (46) formed axially through the base of the non-orbiting scroll for rotatably mounting the crankshaft, whereby rotation of the crankshaft will move the orbiting scroll through an orbit relative to the non-orbiting scroll.</p> |
