ABSTRACT:
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.
