Description

Насто щее изобретение относитс к реактивным аппаратам и движител м .The present invention relates to jet apparatus and propulsive devices.

Особенностью предложенного аппарата вл етс использование и преобразование кинетической энерги , выбрасываемой через диффузор движител воды, пара, газа и т. п., в энергию реактивного давлени .A feature of the proposed apparatus is the use and conversion of the kinetic energy emitted through the diffuser of the propulsion of water, steam, gas, etc., into the energy of reactive pressure.

Аппарат на чертеже представлен в схематическом оформлении на фиг. 1, 2 и 3.The apparatus in the drawing is shown schematically in FIG. 1, 2 and 3.

Внутри диффузора / за соплом 2 помещаетс внутренн рубашка 3. Между этой рубашкой и внешними стенками диффузора / при движении через диффузор жидкости, газа и т. п. образуетс вакуум. За рубашкой 3 установлен обтекатель 4.An inner jacket 3 is placed inside the diffuser / behind the nozzle 2. A vacuum is formed between this jacket and the outer walls of the diffuser / when a liquid, gas, etc. is moving through the diffuser. Behind the jacket 3 is installed fairing 4.

Вода (или газ), вытека из сопла 2 под давлением, приобретает значительную скорость, входит в горловину рубашки 3. Е этом сужении струи воды (газа) достигают такой большой скорости, что по уравнению Бернулли давление делаетс весьма малым. Благодар этому, воздух, заключающийс в пустом пространстве между рубашкой 3 и стенкам.и диффузора /, удал етс .The water (or gas) flowing out of the nozzle 2 under pressure acquires a considerable speed, enters the neck of the shirt 3. At this constriction the stream of water (gas) reaches such a high speed that, according to the Bernoulli equation, the pressure is made very small. Due to this, the air contained in the empty space between the jacket 3 and the walls. And the diffuser / is removed.

На удаление воздуха и на поддержание разреженного затрачиваетс часть кинетической энергии, заключающейс в вытекающей через сопло 2 воде (газе). Вода (газ) будет испытывать тормоз щее действие, которое будет передаватьс ,в виде упорного давлени на стенки рубашки с внутренней стороны диффузора 1.Part of the kinetic energy, consisting in the water (gas) flowing through the nozzle 2, is expended on the removal of air and on maintaining the rarefied. The water (gas) will experience a retarding effect, which will be transmitted, in the form of persistent pressure on the jacket walls from the inside of the diffuser 1.

Остальна часть кинетической энергии, остающейс в вытекающей воде (газе), будет преобразовыватьс в энергию давлени на стенки диффузора / при следовании ее к выходу.The remaining part of the kinetic energy remaining in the outgoing water (gas) will be converted into energy of pressure on the walls of the diffuser (as it follows the outlet).

Дл регулировани степени разр жени от максимума до минимума установлен цилиндр 5 с поршнем 6 внутри, нагруженным пружиной 7. При необходимости понизить разрежение поршень при помощи т ги 8 несколько выдвигаетс , освобожда .отверстие цилиндра, сообщающего пространство рубашки с наружным воздухом. Обратно поршень двигаетс на место пружиной 7.To adjust the degree of discharge from the maximum to the minimum, cylinder 5 is installed with piston 6 inside loaded with spring 7. If necessary, lowering the vacuum piston is pushed out by means of rod 8, releasing the cylinder bore, which communicates the space of the jacket with the outside air. The piston moves back into place with a spring 7.

Дл увеличени упорного давлени на корпус судна, вызываемого работой 1винта, при всасывании передней воды, винт 9 помешаетс в горловине рубашки 3 с таким расчетом, что он будет нагружен работой неTo increase the thrust pressure on the hull of the vessel, caused by the work of a screw, while sucking the front water, the screw 9 will interfere in the neck of the shirt 3 so that it will not be loaded with work

только на всасывание воды (газа), но и на периодическое поддержание вакузма в пустом пространстве А.only for the absorption of water (gas), but also for the periodic maintenance of vacuum in empty space A.

Периодичность работы осуществл етс при помощи эксцентрика JO, приводимого, в действие т гой // от соответствующего кулачкового механизма мотора, а дл улучшени работы диффузора 1 и уменьшени его длины в рубащке , делаютс щели 12, перекрываемые клапанами 13, через которые осуществл етс подсасывание воды к стенкам рубашки 3, идущей в потоке через диффузор.The frequency of operation is carried out using an eccentric JO, driven by a thrust // from the corresponding cam mechanism of the motor, and to improve the operation of the diffuser 1 and reduce its length in the jacket, slots 12 are made, blocked by valves 13, through which water is drawn to the walls of the shirt 3, running in a stream through the diffuser.

Дл безударной работы винта 9 на упорный подщипник вала при пульсирующем действии обтекатель 14 винта 9 закрепл етс на конце вала не намертв о, а на щлицах или щпонках /5. Дл эластичности перемещени обтекател с винтом по валу внутри обтекател на валу установлена пружина 16, упором дл которой служит ограничитель 17, жестко закрепленный на валу.For unstressed operation of the screw 9 on the thrust bearing of the shaft, under the pulsating action, the fairing 14 of the screw 9 is fixed on the end of the shaft not tightly, but on the clamps or tongs / 5. For the elasticity of moving the winding with a screw on the shaft inside the winding, a spring 16 is mounted on the shaft, the stop for which is the stop 17, which is rigidly fixed to the shaft.

В этом случае винт во врем работы вл етс скольз щим, так как во врем увеличени сопротивлени при создании вакуума он вынужден двигатьс вперед но валу, преодолева силу пружины 16 и передава эту силу на упорный подшипник вала. В момент открыти клапана 18 в аппарате и поетуплени воздуха в пространство Л, вакуум в нем уничтожаетс , давление повыщаетс до нормального, а следовательно, и сопротивление винта падает; тогда он под действием пружины 16, отрегулированной на соответствующую силу сопротивлени , начинает двигатьс назад, не прекраща своего вращени и работы.In this case, the screw is slippery during operation, since during an increase in resistance when creating a vacuum, it is forced to move forward but to the shaft, overcoming the force of the spring 16 and transferring this force to the thrust bearing of the shaft. At the moment of opening the valve 18 in the apparatus and loading air into the space A, the vacuum in it is destroyed, the pressure rises to normal, and consequently, the resistance of the screw drops; then, under the action of the spring 16, adjusted to the appropriate resistance force, it begins to move backward, without stopping its rotation and operation.

За врем движени винта назад перекрываетс клапан 18 аппарата и он должен отсосать тот воздух, который вошел в пространство Л. Дойд до заднего предела, винт в}ювь под действием увеличивающегос сопротивлени вынужден двигатьс вперед. Так осуществл етс работа скольз щего винта 9 во все врем действи его.During the movement of the screw back, the valve 18 of the apparatus is closed and it must suck out the air that has entered the space L. The distance to the rear limit, the screw in the body, under the influence of increasing resistance, is forced to move forward. This is how the sliding screw 9 works during the whole time it is operated.
