Abstract
A torque transfer apparatus includes one or more externally powered energy pumps having a plurality of piston and follower arrangements. The pistons are attached to crankshafts, while the associated followers are controlled by a timing chain driven camshaft. The energy pumps are provided with belt drives to power one or more oil pumps, and the oil pumps provide pressurized oil between the followers and pistons so as to improve power transfer efficiency. Additionally, return lines are provided which permit the pressurized oil to be returned to the oil pump during a return stroke of the associated pistons.
