Изобретение относитс к машиностроению , в частности может быть использовано в двигате.пестроении.The invention relates to mechanical engineering, in particular, can be used in engine engineering.
Цель изобретени - упрощение конструкции регулируемого золотникового устройства двухтактного двигател внутреннего сгорани с кривошин«о-камерной продувкой .The purpose of the invention is to simplify the design of an adjustable spool-type device of a two-stroke internal combustion engine with crankshafts by means of an o-chamber purge.
На чертеже изображено устройство, общий вид.The drawing shows the device, the overall appearance.
Золотниковое устройство содержит вал 1, ycTaHOBvieHHbie на не.м плоские распределительные диски 2 и 3 с рабочими кромками 4 и 5, образующими впускное окно переменного сечени , и пружину 6. Распределительный диск 2 выполнен пустотелым и неподвижно закреплен на валу 1, а распределительный диск 3 - в виде массивной пластины, установленной внутри пустотелого диска на оси 7 с возможностью поворота под воздействием пружины 6, ось вращени пластины смещена относительно ее центра т жести.The spool device contains a shaft 1, ycTaHOBvieHHbie on a new flat distribution discs 2 and 3 with working edges 4 and 5, forming an inlet window of variable section, and a spring 6. The distribution disc 2 is hollow and fixed on the shaft 1, and the distribution disc 3 - in the form of a massive plate installed inside a hollow disk on axis 7 so that it can be rotated under the influence of spring 6, the axis of rotation of the plate is offset relative to its center of gravity.
Устройство работает следующим образом .The device works as follows.
При вращении золотника в направлении, указанном на чертеже стрелкой, начало фазы впуска топливовоздушной смеси в кри- воплипную камеру определ етс рабочей кромкой 4 распределительного диска 2, а конец - рабочей кромкой 5 диска 3. Положение последнего определ етс соотношением противоположно направленных сил:When the spool rotates in the direction indicated in the drawing by the arrow, the beginning of the phase of the intake of the air-fuel mixture into the cryglass chamber is determined by the working edge 4 of the distribution disc 2, and the end by the working edge 5 of the disk 3. The position of the latter is determined by the ratio of opposite forces:

центробежной и от действи пружины 6. При малой частоте вращени центробежна сила мала и под воздействием пружины 6 диск 3 занимает положение, соответствующее минимальному значению проходного сечени впускного окна. При больших частотах вращени под воздействием возросшей центробежной силы пружина 6 сжимаетс и диск 3 поворачиваетс на оси 7, увеличива площадь проходного сечени золотника. Тем самым обеспечиваетс оптимальное наполнение кривошипной камеры во всем диапазоне частот вращени вала двигател .centrifugal and from the action of the spring 6. At a low frequency of rotation, the centrifugal force is small and under the influence of the spring 6 the disk 3 occupies the position corresponding to the minimum value of the flow area of the inlet port. At high rotational frequencies under the influence of increased centrifugal force, the spring 6 is compressed and the disk 3 rotates on the axis 7, increasing the flow area of the spool. This ensures optimum filling of the crank chamber over the entire frequency range of rotation of the engine shaft.
