Abstract
1. Газораспределительный механизм четырехтактного двигателя внутреннего сгорания, содержащий два составных распределительных вала, каждый из которых установлен на подшипниках в головке блока цилиндров и представляет собой поворотное золотниковое устройство с внешним вращающимся золотником, имеющим входные и выходные окна, и с внутренним золотником, обеспечивающим за счет поворачивания регулировку длительности фаз газораспределения, имеющим каналы, оси которых расположены в плоскостях его поперечного сечения, размещенные с возможностью совмещения с окнами внешнего золотника. ! 2. Механизм по п.1, отличающийся тем, что каждый канал в головке блока цилиндров снабжен компенсатором теплового изменения зазора в виде радиально подпружиненного элемента, имеющего канал смазки, установленного со стороны камеры сгорания и прилегающего к внешнему золотнику. ! 3. Механизм по п.2, отличающийся тем, что компенсатор теплового изменения зазора выполнен методом порошковой металлургии и имеет капиллярные каналы смазки. ! 4. Механизм по любому из пп.1 или 2, отличающийся тем, что головка блока цилиндров выполнена разъемной из верхней и нижней частей, сопряженных в плоскости продольных осей золотниковых устройств. ! 5. Механизм по любому из пп.1 или 2, отличающийся тем, что привод внешнего золотника выполнен от шкива коленчатого вала, а внутреннего золотника - от шагового электродвигателя. ! 6. Механизм по п.5, отличающийся тем, что привод внешнего золотника оснащен муфтой регулировки углов открытия. ! 7. Механизм по любому из пп.1 или 2, отличающийся тем, что внешний золотник выполнен с прямолинейной образующей. ! 8. Механизм по любому и1. The gas distribution mechanism of a four-stroke internal combustion engine, containing two composite camshafts, each of which is mounted on bearings in the cylinder head and is a rotary spool device with an external rotating spool having input and output windows, and with an internal spool providing turning the adjustment of the duration of the valve timing, having channels, the axes of which are located in the planes of its cross section, placed with possible Stu alignment with the windows of the external valve. ! 2. The mechanism according to claim 1, characterized in that each channel in the cylinder head is equipped with a compensator for the thermal change in the gap in the form of a radially spring-loaded element having a lubricant channel mounted on the side of the combustion chamber and adjacent to the external spool. ! 3. The mechanism according to claim 2, characterized in that the compensator for the thermal change in the gap is made by the method of powder metallurgy and has capillary channels of lubrication. ! 4. The mechanism according to any one of claims 1 or 2, characterized in that the cylinder head is made detachable from the upper and lower parts mated in the plane of the longitudinal axes of the spool devices. ! 5. The mechanism according to any one of claims 1 or 2, characterized in that the external spool drive is made from a crankshaft pulley, and the internal spool is from a stepper motor. ! 6. The mechanism according to claim 5, characterized in that the external spool actuator is equipped with a clutch for adjusting the opening angles. ! 7. The mechanism according to any one of claims 1 or 2, characterized in that the outer spool is made with a rectilinear generatrix. ! 8. The mechanism of any and
