Изобретение относитс к испытани м двигателей внутреннего сгорани .This invention relates to testing of internal combustion engines.

Известны газоотборочиые клапаны, содержащие расположенный в корпусе подпружиненный клапанньй элемент, нагружеиньй пружиной ударник, имеющий ограничитель хода, устройство взвода и боек с головкой.Known gas valves containing a spring-loaded valve element located in the housing, a spring loaded drummer having a travel stop, a cocking device and a head with a hammer.

В известном клапане невозможно регулировать врем -сечение клапана и высоту его подъема.In the well-known valve, it is impossible to adjust the time-section of the valve and the height of its rise.

Цель изобретени - регулирование врем сечени открыти . Дл этого боек вьшошен откидным на оси, установленной в ударнике, и имеет вблкзк головки заплечики, взаимодействующие с фигурным ножом в основаНИИ ударника. :Корпус вблизи ограничител , хода содержит поворотную втулку, имеющую винтовой паз, св занный с фигурным ножом.The purpose of the invention is to regulate the opening time of the cross section. For this, the striker was mounted flush on the axis installed in the drummer, and has a shoulder in its head, which interacts with the figure knife in the base of the drummer. : The body is near the limiter, the stroke contains a rotatable sleeve having a helical groove associated with the figure knife.

На чертеже показан продольный разрез клапана.The drawing shows a longitudinal section of the valve.

В газоотборочном клапане клапанный элемент 1 установлен с пружиной 2 и направл ющей втулкой 3 в корпусе 4 клапана . Корпус 4 клапана соединен с корпусом 5 ударника, а между ними зажимаетс ограничитель-хода 6 ударника. В корпусе 5 уданика установлена его пружина 7, направл « .юша втулка8, .зажимна втулка 9 и сам ударник 10. В осевом отверстии ударника 1О установлен бэек 11, состо щий из двух откидных секций, имеюцщх заплечики 12 вблизи головки бойка 11. Откидньв секции сид т на оси 13 и имеют возвратную пружину 14. В основании ударника 1О установлен фигурный нож 15, который входит в нижнюю часть секции бойка 11 и св зан через отверстие в корпусе ударника вблизи ограничител хода 6 винтовым пазом поворотной втулки 16 корпуса 5. Фигурный нож взаимодействует с заплечиками 12 oivкидных секций бэйка 11. Дл удержани ударника 1О во взведенном состо нии служат собачки 17, имеющие ось вращени 18 и пружины 19. Собачки удерн иваютс хомутиком. 20, Дл срабатывани клапана служит электромагнит 21.In the gas sampling valve, the valve element 1 is installed with a spring 2 and a guide bushing 3 in the valve body 4. The valve body 4 is connected to the hammer body 5, and the shock-stop valve 6 is clamped between them. In the body 5 of the udanik, its spring 7 is installed, the direction of the sleeve 8, the clamping sleeve 9 and the drummer 10 itself. In the axial hole of the drummer 1O there is a back-end 11, consisting of two folding sections that have shoulders 12 near the head of the strike 11. Folding section sit on axis 13 and have a return spring 14. At the base of the drummer 1O, a figure knife 15 is installed, which enters the lower part of the striker section 11 and is connected through an opening in the drummer body near the travel stop 6 by a helical groove of the rotary sleeve 16 of the case 5. Figured knife interacts with the shoulder There are 12 oiv-shaped sections of the tank 11. To keep the striker 1O in the cocked state, the dogs 17 have an axis of rotation 18 and springs 19. The dogs are squeezed by a clamp. 20, An electromagnet 21 serves to trigger the valve.

Claims

In order to take a sample of gas in a certain phase of the internal combustion engine cycle, a current is supplied to the electromagnet 21 with some advance. The electromagnet rod resets the clutch 20, Dogs 1-7 are thrown away | A drummer-10 with a striker 11 rushes down. The hammer 11 hits the valve element 1 and continues to move with it until the figure knife 15 interacts with the aeples 12, and © spreads the striker section 11, the hammer 11 with the sliding sections comes out of contact with the valve element 1 and forms between sections 1 a linear cavity, where the shaft of the valve element 1 freely enters when it returns in response to the spring 2, the adjustable height of the valve element 1, the adjustable time-section, as well as the reduction in the valve response time allow explore it for the workflow of high-speed internal combustion engines. / Claim 1, Gas sampling valve for single-use sampling of high-volume gas, containing a spring-loaded valve element in the housing, a spring loaded drummer with a travel stop, device for arming and striker head. This is characterized by the fact that, in order to regulate the time of the opening section, the firing pin is made folding on the axis installed in the drummer and has shoulder-pieces close to the head, which are acting with a figured knife at the base of the impactor, I. 2 This is due to the fact that the body near the stroke limiter contains a rotary sleeve having a BINT groove associated with a figure knife.
