Abstract
In a co-rotational scroll apparatus having two interleaving scroll wraps 80, 100 secured to end plates 82, 102 rotating about parallel, non-concentric axes to produce a relative orbital motion, a means for enhancing lubricant flow through the scroll wraps is provided. One or more passages 200 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 220 affixed to the scroll end plates 102 and inlet openings 216 in the scroll end plates. The inlet openings 216 accept lubricant discharged from the bearings 110 in the apparatus. The pickup tubes rotate with the scroll end plates and remove lubricant from a sump 222 adjacent the scroll end plates. In other embodiments (see Figs 4-9) different arrangements are used and the pickup tubes may be omitted, as in Figs 5 and 7. <IMAGE>
