Description

Изобретение касаетс  известного устройства дл  изменени  фаз газораспределени  в двигател х внутреннего сгорани . Эти устройства имеют гидравлическую передачу от кулачка распределительного вала к штоку клапана. В них предусмотрено пополнение утечек рабочей жидкости. Предлагаемое устройство отличаетс  тем, что с целью изменени  моментов открыти  или закрыти  клапана применен дополнительный кулачок дл  управлени  клапаном, разобщающим канал гидравлической передачи от питающей внешней сети.The invention relates to a known device for changing valve timing in internal combustion engines. These devices have a hydraulic transmission from the cam of the camshaft to the valve stem. They provide for the replenishment of leakage of working fluid. The proposed device is characterized in that in order to change the moments of opening or closing of the valve, an additional cam is used to control the valve, which divides the hydraulic transmission channel from the external power supply network.

На чертеже схематически изображен продольный разрез предлагаемого устройства дл  изменени  фаз газораспределени  в двигател х внутреннего сгорани .The drawing shows schematically a longitudinal section of the proposed device for variable valve timing in internal combustion engines.

Устройство выполнено в виде качающегос  коромысла /. Толкатель 2, наход сь под посто нным давлением масла, поступающего из масл ной системы через разобщающий клапан 3 в канал 7, соприкасаетс  со щтоком 5 клапана или насоса-форсунки. При передаче усили  от кулачка 6 на коромысло клапан .3, сбега  с верщины 8 дополнительного кулачка 4, закрываетс . При этом толкатель 2 давит на щток 5,The device is designed as a rocker arm. The pusher 2, being under the constant pressure of the oil coming from the oil system through the uncoupling valve 3 into the channel 7, is in contact with the valve stem 5 or the pump nozzle. When force is transferred from the cam 6 to the rocker arm, the valve .3, running down from the top 8 of the additional cam 4, closes. In this case, the pusher 2 presses on the brush 5,

Изменение момента закрыти  клапана 3 и тем самым изменение фаз газораспределени  в двигателе осуществл етс  поворотом дополнительного кулачка 4.The change in the moment of closing of the valve 3 and thereby the change in the valve timing in the engine is accomplished by turning the additional cam 4.

поворота кулачка 4 можно использовать центробежный регз-л тор либо прибор, реагирующий на изменение давлени  во всасывающе .м или выхлопном трубопроводе. By turning the cam 4, a centrifugal regulator can be used, or a device that responds to pressure changes in the suction pipe or exhaust manifold.
