Abstract
A rotary machine is powered by a drive shaft having a bore extending through it. A single piece lubricant flinger is disposed within the bore to form a lubricant pump. The lubricant flinger includes an upper plate located within the bore and a washer located adjacent the opening of the bore. The washer is connected to the upper plate by a connection section and the washer defines an aperture which allows fluid to flow into the bore of the shaft.
