ABSTRACT:
A scroll type fluid displacement apparatus is disclosed, which includes a housing having a front end plate and a cup shaped casing. A fixed wrap extends into an operative interior area of the casing from an inner end surface of an end plate portion of cup shaped casing. An orbiting scroll has an end plate from which an orbiting wrap extends, and a tubular member axially projects from the end surface of end plate into the operative interior area of the casing. The tubular member has a hollow interior at its center. A drive shaft is rotatably supported by the front end plate and a crank pin extends from its inner end surface. The crank pin is rotatably carried within the hollow interior of the tubular member through a bearing to thereby rotatably support the orbiting scroll. A balance-weight is fixed on the axial end portion of the crank pin to cancel the dynamic unbalance caused by the centrifugal force of the orbital moving parts.
