DETAILED DESCRIPTION OF THE INVENTION
[0019] The devices and methods discussed herein are merely illustrative of specific manners in which to make and use this invention and are not to be interpreted as limiting in scope.
[0020] While the devices and methods have been described with a certain degree of particularity, it is to be noted that many modifications may be made in the details of the construction and the arrangement of the devices and components without departing from the spirit and scope of this disclosure, it is understood that the devices and methods are not limited to the embodiments set forth herein for purposes of exemplification.
[0021] In general, in a first aspect, the invention relates to a hydrogen powered rotary energy transducer. The energy transducer utilizes hydrogen rather than fossil fuels, capturing the energy within the hydrogen. As used herein, hydrogen may refer to a mixture of hydrogen and oxygen. In the present invention, the energy from the hydrogen is converted to power by a pump, such as a piston pump, rotary pump, thrust pump, or gear pump. The energy transducer may utilize a single pump or multiple pumps in any configuration. Figures 1 through 4 show a single rotary pump, comprising a body I , a rotor 2, and a crankshaft 1 1.
[0022] The energy transducer may comprise a body 1 housing the rotor 2 such that the rotor 2 may freely rotate within the body 1 along an axis defined by the crankshaft 1 1 . One or more chambers 3 may be located circumferentially around the rotor 2. The chambers 3 may be angled inward toward the direction of travel of the rotor 2, as seen in Figures 1 through 3. A direct injector 5 may be connected to the body 1 such that the direct injector 5 may inject hydrogen into the chambers 3 one at a time as the rotor 2 rotates. A hydrogen control valve 7 may be connected to the direct mjector 5 to control the amount of hydrogen injected into the chambers 3. A hydrogen storage tank 10 may be in fluid communication with the direct injector 5 via the hydrogen control valve 7. [0023] An igniter 4, such as a spark plug, may likewise be connected to the body 1 such that the igniter 4 may ignite the hydrogen within the chamber 3. The igniter 4 may be located near the injector 5, but further along the path of rotation of the rotor 2. The igniter 4 may be out of phase with the injector 5, such that when a chamber 3 is aligned with the igniter 4, there is not a chamber 3 aiigned with the injector 5; likewise, when a chamber 3 is aligned with the injector 5, there is not a chamber 3 aiigned with the igniter 4. An exhaust port 6 may also be located within the body 1 such that it may vent exhaust from the chambers 3 after ignition. The exhaust port 6 may be located near the injector 5, but before the injector 5 along the path of rotation of the rotor 2. The exhaust port 6 may also be out of phase with the injector 5, such that when a chamber 3 is aiigned with the exhaust port 6, there is not a chamber 3 aligned with the injector 5, and when a chamber 3 is aligned with the injector 5, there is not a chamber 3 aligned with the exhaust port 6. An electronic controller 8 may be connected to the igniter 4 and the hydrogen control valve 7, thus controlling the overall function of the transducer, '['he electronic controller 8 may be connected to a throttle 9, such that an operator of a vehicle utilizing the transducer may control the transducer via the throttle 9.
[0024] In use, the rotor 2 begins with a chamber 3 aligned with the injector 5. The injector 5 injects hydrogen into one of the chambers 3. The rotor 2 rotates such that the chamber 3 bearing hydrogen is aligned with the igniter 4. The igniter 4 fires, causing the hydrogen in the chamber 3 to explode. This explosion forces the rotor 2 to rotate, which in turn causes the crankshaft 1 1 to rotate. This movement may be seen in Figures 2 and 3. When the chamber 3 in which the explosion occurred reaches the exhaust port 6, exhaust is removed from the chamber 3. The process is repeated cyclically for each of the chambers 3. [0025] The energy/RPMs of the energy transducer may be controlled by the timing and/or size of the explosion of the hydrogen. The size of the chambers 3 is not important; the size of the rotor 2 controls the amount of power it makes.
[0026] Whereas, the devices and methods have been described in relation to the drawings and claims, it should be understood that other and further modifications, apart from those shown or suggested herein, may be made within the spirit and scope of this invention.
