摘要：
A variable output gerotor oil pump of the kind having a common rotor with n teeth meshed with two axially juxtaposed internally lobed annuli with n+1 teeth has the annuli individually located in eccentrics formed with gear teeth to be turned in opposite directions by a gear drive. The teeth are straight cut, not bevel, and the drive includes an intermediate pinion so that a single shaft turns the eccentrics in opposite directions.
