Abstract
A variable output gerotor pump includes outer and inner driven and driving rotors and an annular output control ring which is rotatable within a bore mounted within the pump's body so as to change the amount of working fluid which is transferred from the inlet port to the outlet port of the pump. This is particularly useful for controlling the output flow of lubricating oil used in an internal combustion engine.
