Abstract

Title SCROLL APPARATUS
WITH ENHANCED LUBRICANT FLOW

Inventors Robert E. Utter Daniel R. Crum Peter A. Kotlarek Abstract In a co-rotational scroll apparatus having two interleaving scroll wraps secured to end plates rotating about parallel, non-concentric axes to produce a relative orbital motion, a means for enhancing lubricant flow through the scroll wraps. One or more passages are provided in one or both of the scroll end plates, each passage disposed to discharge lubricant between the scroll end plates, discharging adjacent the outer end of the scroll wraps immediately before the point where the scroll wraps form the first compression chamber to provide lubricant to the entire scroll wrap length. Lubricant is provided to the passages by a combination of pickup tubes affixed to the scroll end plates and inlet openings in the scroll end plates. The inlet openings accept lubricant discharged from the bearings in the apparatus. The pickup tubes rotate with the scroll end plates and remove lubricant from a sump adjacent the scroll end plates.
