Abstract

The new device consists of a variable volume rotating double pump that receives motion from the propulsion unit and other constant volume pumps that function as reduction gears and are mechanically connected to the half shafts of the wheels and, by means of fluid pipes, to the variable-volume double pump. Each section of the variable-volume double pump is fitted with a system of two cam rings, coupled one inside the other, of which the innermost one forms the walls against which the blades of the pump rotor exert pressure. Rotating these cam rings, by means of a hydraulic servo mechanism, varies the geometry of the pump, thereby determining the volume of fluid pumped and the direction of pumping; in this way the pressure exerted by the variable volume double pump on the fluid is transmitted to fixed volume reduction gears that transmit their rotary motion to the wheels. <IMAGE>
