Abstract:
1. A lubricant metering system for a compressor comprising: a cap including an outer surface, a first recess, and a first radial bore extending between said first recess and said outer surface; a cap cage including a second recess receiving said cap and a lubricant inlet in communication with said first recess via said first radial bore; and a shaft received within said first recess and including an axially extending bore and a second radial bore extending between an outer diameter of said shaft and said axially extending bore, said shaft is mounted for rotation relative to said cap to allow lubricant to flow into said axially extending bore via said first and second radial bores when said second radial bore is aligned with said first radial bore, wherein a high-pressure lubricant reservoir disposed between said cap cage and said cap axially biases said cap.
