Description
ку 4 гильзы 1 проход т, как минимум, два радиальных канала 23, соедин ющих перспускиую камеру 8 с системой смазки двигател носредство.м канала 24. Перепускную камеру 8 со стороны кулачкового вала 15 закрывает защитна втулка 25.The sleeve 4 4 passes through at least two radial channels 23 connecting the inlet chamber 8 to the engine lubrication system of the vehicle 24 of the channel 24. The overflow chamber 8 from the side of the camshaft 15 closes the protective sleeve 25.
Шестерн нривода насоса соединена со щлнцами 5 гнльзы {. Канавки 4 предназначены дл подвода гй;1сла в нереиускную камеру 8 и смазки щестерни нривода.Gear of the pump drive is connected with sleeves 5 gnlzy {. The grooves 4 are intended for supplying the gyr; 1sl into the non-diffusor chamber 8 and lubricating the nesting brush.
Устройство работает следуюатим образом.The device works as follows.
Масло из системы е.мазки двигател ио каналам 24 и 23 поступает в перепускную камеру 8, а затем по каналам 22, 21, 16, 18 и 19 - в камеру сжати 7. При возврастании момента сопротивлени ироворачиванию -вала в начале нагнетаии топлива насосом высокого давлени поршень 6 проворачиваетс по резьбе 9 с большим шагом и одновременно перемещаетс по шлицам г-; в направлеии п камеры сжати 7. Давление масла и камереOil from the engine e. Engine lubrication system to channels 24 and 23 enters the bypass chamber 8, and then through channels 22, 21, 16, 18 and 19 - into the compression chamber 7. When the moment of resistance increases, the pump starts to pump high pressure piston 6 rotates along the thread 9 with a large pitch and at the same time moves along the splines r-; in the direction of the compression chamber 7. Oil pressure and chamber
7возрастает, .клапан 11 перекрывает осевое отверстие 16, и дальнейшее перетекание масла в перепускную камеру в нрсщессе топливоподачи происходитчерез жккле-; ; 7. После окончани впрыска момент соп,)ст;;влени вала 15 резко падает, и упругие о:и;ы, сопр женных деталей и пружины 13 возвращают поршень в исходное иоложение до упора в торец вала 15. Приэтом давление масла в камере 7 increases, the valve 11 closes the axial bore 16, and the further flow of oil into the bypass chamber in the fuel flow takes place through the glass; ; 7. After the injection is finished, the moment of const,) Art ;; of the shaft 15 drops sharply, and elastic about: and; s, the mating parts and the spring 13 return the piston to its original position until it stops at the end of the shaft 15. With this, the oil pressure in the chamber
8преодолевает силу пружины 12, и масло поступает оп ть в камеру 7. Возрастание момента сопротивлени вала 15 при следующем впрыске сопровождаетс повторением цикла работы устройства.8 overcomes the force of the spring 12, and the oil enters the chamber 7 again. The increase in the moment of resistance of the shaft 15 in the next injection is accompanied by a repetition of the cycle of operation of the device.
При увеличении угловой скорости вала 15 врем на перетекание масла из камеры сжати 7 в перепускную камеру 8 умеиьшаетс , порще-нь отходит от торца вала 15 па меиыиее рассто ние, и угол опережени впрыска возрастает .With an increase in the angular velocity of the shaft 15, the time for the flow of oil from the compression chamber 7 into the overflow chamber 8 decreases, the damage moves away from the end of the shaft 15 by the distance, and the advance angle of injection increases.
После остановки двигател масло стекает из камер 8 и 7, поэтому при пуске поршень имеет возможность без сонротивлени масла перемещатьс до упора в опорную тарелку 20, тем самым обеспечива необходимое уменьшение угла опережени впрыска.After the engine stops, the oil flows out of chambers 8 and 7, therefore, when starting, the piston has the ability, without an oil resistance, to move against the stop into the support plate 20, thereby providing the necessary reduction in the advance injection angle.
