Oil pump with dual scavenging for a twin cam engine

An oil pump used in combination with an engine, comprising:

• a high pressure gerotor and cam chest scavenger gerotor first housing comprising a top inset and a bottom inset;
• a separator plate disposed above said first housing that enables an independent passageway dual scavenging capability of said oil pump;
• a crankcase sump scavenger gerotor second housing comprising a bottom inset disposed above said separator plate;
• a high pressure gerotor disposed below said first housing bottom inset that pulls oil from an oil reservoir through a first separate passageway and supplies the oil from the oil reservoir under pressure through a cam plate to said engine;
• a cam chest scavenger gerotor disposed in said top inset of said first housing below said separator plate capable of independently scavenging oil in a cam chest sump of said engine through a second separate passageway and returning the oil from the cam chest sump to said oil reservoir;
• a crankcase sump scavenger gerotor disposed in said second housing bottom inset above said separator plate capable of independently scavenging oil in said crankcase sump of said engine through a third separate passageway and returning the oil from the crankcase sump to said oil reservoir;
• and
• an o-ring disposed beneath said high pressure gerotor to prevent oil from leaking into said cam chest of said engine, wherein said cam chest scavenger gerotor is capable of independently providing a dry cam chest sump and said crankcase sump scavenger gerotor is capable of independently providing a dry crankcase sump.
