Abstract
A lubricant metering system for a compressor may include a cap, a cap cage, and a shaft. The cap may include an outer surface, a first recess, and a first radial bore extending between the first recess and the outer surface. The cap cage may include a second recess receiving the cap and a lubricant inlet in communication with the first recess via the first radial bore. The shaft may be received within the first recess and may include an axially extending bore and a second radial bore extending between an outer diameter of the shaft and the axially extending bore. The shaft may be mounted for rotation relative to the cap to allow lubricant to flow into the axially extending bore via the first and second radial bores when the second radial bore is aligned with the first radial bore.
