Abstract
A fluid pump cowling for attachment to at least a pair of helical drivetrain gears having teeth and lands. The cowling has a pair of sidewalls adapted to extend at least partially over the lands of a first of the pair of drivetrain gears and a curved sump wall extending between the sidewalls that corresponds generally to the outermost circumference of the first gear. A sump channel is defined between the sidewalls on the sump wall adjacent a distal end of the sump wall. The sump channel has a generally frustoconical shape and leads to a fluid outlet opening defined in one of the sidewalls. The cowling is positioned such that the teeth of the pair of helical gears mesh in an area in fluid communication with the sump channel to create an area of high fluid pressure upon rotational movement of the gears with a fluid.
