Abstract:
1. A scroll compressor, comprising: a fixed scroll; a front case having inner circumferential surfaces disposed in an inner end surface of the front case; an orbiting scroll engaged with the front case and configured to orbit the fixed scroll by operation of a driving member; and a single pin paired with each one of the inner circumferential surfaces the single pin engaging the orbiting scroll via the paired circumferential surface of the front case, the paired pins and inner circumferential surfaces configured to prevent rotation of the orbiting scroll; wherein an orbiting radius, defined by the pins and the inner circumferential surfaces, is larger than a theoretical orbiting radius defined by engagement between gear surfaces of the fixed scroll and the orbiting scroll; and wherein the pins or the inner circumferential surfaces are shifted in a direction as to relieve twisting of the orbiting scroll relative to the fixed scroll.
