Abstract
A scroll compressor oil circulation system has the usual concentric bore oil pump which supplies lubricating oil to a chamber within which an impeller rotates. The rotating of the impeller within this chamber pumps lubricating oil through a passage which communicates with a control passage which injects a quantity of lubricant into the compression chambers of the scrolls for cooling and lubrication. The amount of oil injected into the compression chamber is controlled by the shape of the control passage through the orbiting scroll.
