Abstract
This invention provides the use of a pump to regulate torque in a planetary gear system. The pump is provided with a bore and a valve, which operates to control the flow of fluid within the bore. When the valve is positioned within the bore to block the flow of fluid between the inlet and outlet of the pump, pressure is generated within the pump. The pump pressure is sufficient to generate torque in the planetary gear system.
