Claim:
An oil pump, comprising: a first housing comprising a top inset and a bottom inset; a separator plate disposed above said first housing that enables an independent dual passageway scavenging capability of said oil pump; a 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 an 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.
