摘要： The damper is comprised of a set of core rotor magnets arranged in an opposing north/south configuration. A conducting material cylindrically encircles the rotor magnets. A set of stator magnets laterally encircle the conducting material and are arranged in the same manner as the rotor magnets. A system of gears are coupled to the damper shaft and control the rotation of the rotor magnets such that they can be positioned relative to the stator magnets to set up the desired damping torque. As the rotor and stator magnets of opposite polarity approach each other, the eddy-current in the rotating conducting material increases causing the conducting material to generate a field in response to the eddy-current. The damping torque is caused by the magnetic force generated when the induced field in the material and the stator/rotor field attempt to line up.

摘要： A gas/air mixer assembly provides a Venturi metering system that may draw fuel from a zero governor, mix it with air to form a homogenous gas/air mixture for delivery to an internal combustion engine. The gas/air mixer assembly may also accept fuel under pressure from a gas metering valve or fuel injector for delivery to an internal combustion engine. The mixer includes an air horn, the relative position of which in relation to a shaped restriction body governs the air flow into the engine intake manifold. The flange of the air horn is configured to redirect the flow of air without generating significant turbulence, and providing a maximum velocity perpendicular flow to the injection of fuel to be mixed therein. The relative position of the air horn to the shaped restriction body is determined based on the cubic capacity and speed of the engine with which it is used.
