An open drive scroll compressor had a unique lubrication system which includes a vane type oil pump attached to an outer diameter of the drive shaft of the compressor. The oil pump draws oil from an oil sump, sends a first portion of the oil to the components of the compressor needing lubrication and a second portion through a filter. The return to the sump from the filter is restricted to control oil pressure and thus the amount of circulated oil. The scroll compressor includes a first baffle between the oil sump and a counterweight attached to the drive shaft and a second baffle disposed between the scroll members and the oil sump.

[ What is claimed is:] [1.] A scroll machine comprising:a compressor body defining a chamber and an internal cavity;a first scroll member disposed within said internal cavity; said first scroll member having a first spiral wrap;a second scroll member disposed within said internal cavity, said second scroll member having a second spiral wrap intermeshed with said first spiral wrap;a drive shaft rotatably supported with respect to said compressor body, said drive shaft receiving rational input and transferring said rotational input to one of said scroll members for causing said scroll members to orbit relative to one another whereby said spiral wraps will create pockets of progressively changing volume between a suction pressure zone of said internal cavity and a discharge pressure zone of said internal cavity;an oil distribution system disposed with said chamber and said internal cavity, said oil distribution system comprising:an oil sump disposed within said suction pressure zone of said internal cavity; andan oil pump attached to an outer surface of said drive shaft, said oil pump being powered by said driveshaft to pump oil from said oil sump, to components of said scroll machine requiring lubrication.
