Description
поверхность перемещаетс и, поскольку он посажен на вннтовой направл юш,ей, поворачиваетс вокруг оси центрального тела 2. При этом он приводит .во .вращение тарель 7, поскольку св зан с ней посредством продольных направл ющих 8. В результате тарель 7 перемещаетс вдоль оси центрального тела 2, поскольку она посажена на винтовой направл ющей 5, и уменьщает проходное сечение сопла. Дл увеличени проходного сечени необходимо переместить золотник 4 так, чтобы разъединить отверсти 10 и И частично или полностью. Тогда давление газа внутри полости 13 частично или полностью падает, и тарель 7 под действием давлени газа на ее внещнюю поверхность передвигаетс вдоль оси центрального тела, при этом она поворачиваетс и поворачивает вокруг оси центрального тела 2 норщень 9, в результате чего он также перемещаетс навстречу тарели7. Виброустойчивость и нечувствительность к перегрузкам в предлагаемом устройстве обеспечиваетс тем, что св зь между поршнем и тарелью выполнена в виде винтовых направл ющих противоположной закрутки, а массыthe surface moves and, since it is planted on the outer direction, it rotates around the axis of the central body 2. At the same time, it causes the rotation of the plate 7, since it is connected with it by means of the longitudinal guides 8. As a result, the plate 7 moves along the axis the central body 2, since it is seated on the helical guide 5, and reduces the flow area of the nozzle. To increase the flow area, it is necessary to move the spool 4 so as to separate the holes 10 and AND partially or completely. Then the pressure of the gas inside the cavity 13 partially or completely drops, and the plate 7 under the action of gas pressure on its external surface moves along the axis of the central body, while it rotates and turns around the axis of the central body 2 Nor 9, as a result of which it also moves towards the plate 7 . Vibration and insensitivity to overloads in the proposed device is ensured by the fact that the connection between the piston and the plate is made in the form of screw guides of opposite spin, and the masses
порщн и тарели выбраны равными по Величине .Porshn and plateau are selected equal in magnitude.
В св зи с совмещением порщн и тарели габариты и вес регулировочного сопла значительно уменьшены, а быстродействие увеличено .Due to the combination of the pressure plate and plate, the dimensions and weight of the adjusting nozzle are significantly reduced, and the speed is increased.
