Abstract
A device for providing a retarding force against the motion of a vehicle, which device does not intrude upon the engine, is not dependent upon the vehicle gear selected, and does not exhibit fade or skid characteristics. A multiple plate clutch engages the drive train of the vehicle with a compressor assembly. A three speed gear assembly is operatively connected between the multiple plate clutch and the providing modulation of the ratio of speed between the aerodynamic rotor and the drive train. A throttle valve governs the fluid mass flow through the rotor of the compressor assembly providing precise modulation of retarding torque exerted by the rotor. The device may also be adapted for other types of machines and motors having rotating shafts upon which it is desired to apply a retarding torque.
