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 providing positive lubricant flow through the scroll wraps. A sump is provided adjacent the idler scroll member for supplying lubricant to a lubricant pump disposed in the lower end of the shaft of one scroll member. A lubricant gallery is provided in the scroll shaft for receiving the lubricant from the pump and directing the lubricant through passages in the scroll shaft to lubricate the scroll shaft bearing and for directing lubricant to passages in the end plate of the scroll member to be discharged adjacent the outer ends of the scroll wraps into the alternatively open and closed first chamber formed by the scroll wraps.
