ABSTRACT:
A high side co-rotational scroll compressor has lubricant sumps in both the discharge and suction pressure portions of its hermetic shell as well as a pressure biasing arrangement by which the scroll members are urged together in operation to minimize internal leakage. Lubrication of the bearing in which the driven scroll member rotates as well as to the bearing in which the idler scroll member rotates, both of which are located in the suction pressure portion of the shell, is provided for. Additionally, embodiments are taught by which the interface between the tips of the wraps of each scroll member and the end plate of the opposing scroll member are lubricated and by which the seal in the axial pressure biasing arrangement is lubricated and/or shielded from debris having the potential to damage it.
