Abstract
Изобретение м.б. использовано в карбюраторах бензиновых двигателей вйутреннего сгорани . Цель изобретени - упрощение фиксации винта холостого хода. Колпачок 3 с шлицом 4 под инструмент, напрессованньп на головку винта 2 холостого хода, установлен в гнезде 5, выполненном в корпусе карбюратора 1. На цилиндрической поверхности гнезда и наружной поверхности колпачка выполнены треугольные шлицы 6 с возможностью их сопр жени . Глубина внутренней полости 7 колпачка равна максимальной величине выступани винта в гнездо. Такое вьшолнение позвол ет снизить трудоемкость процесса регулировки и фиксации винта на автомобиле, исключа неквалифицированное вмешательство в регулировку карбюратора. 2 ил.Invention m. Used in carburetors for vnutrennogo combustion engines. The purpose of the invention is to simplify the fixation of the idling screw. The cap 3 with the slot 4 for the tool, pressed onto the head of the screw 2 of idling, is installed in the slot 5 made in the carburettor case 1. On the cylindrical surface of the socket and the outer surface of the cap there are triangular slots 6 with the possibility of their matching. The depth of the inner cavity 7 of the cap is equal to the maximum protrusion of the screw in the socket. Such an implementation reduces the laboriousness of the process of adjusting and fixing the screw on the car, eliminating unqualified intervention in the adjustment of the carburetor. 2 Il.

Изобретение относитс к машиностроению , .в частности к двигателе- строению, а именно к карбюраторам бензиновых двигателей внутреннего сгорани .The invention relates to mechanical engineering, in particular, to engine construction, namely to carburetors of gasoline internal combustion engines.
Целью изобретени вл етс упрощение фиксации винта холостого хода.The aim of the invention is to simplify the fixation of the screw idling.
На фиг. 1 изображено устройство дл фиксации винта холостого хода, продольный разрез; на фиг. 2 - то же поперечный разрез.FIG. 1 shows a device for fixing a screw idling, a longitudinal section; in fig. 2 - the same cross section.
В корпус 1 карбюратора ввернут винт 2 холостого хода с напрессованным на него колпачком 3, который выполнен из пластмассы и имеет на наружной поверхности шлицы 4. На внутренней поверхности гнезда 5 расположены шлицы 6 таким образом, чтобы они имели возможность входить в зацепление с шлицами на колпачке при перемещении его вдоль оси головки винта; колпачок имеет внутренюю полость 7.Screw the idling screw 2 with the cap 3 pressed onto it in the carburetor body 1, which is made of plastic and has splines 4 on the outer surface. Splines 6 are located on the inner surface of slot 5 so that they can engage with the splines on the cap when moving it along the axis of the screw head; the cap has an internal cavity 7.
Количество пшицов на колпачке и корпусе выбрано из услови обеспечени оптимальной чувствительности винта холостого хода при регулировке системы х;олостого хода по составу смеси, надежной фиксации винта в корпусе , а также исход из технологических возможностей вьшолнени шлицево- го соединени .The number of pshits on the cap and the body is selected from the condition of ensuring the optimum sensitivity of the idling screw when adjusting the system x, the pilot motion in the mixture, reliable fixation of the screw in the body, and also proceeding from the technological capabilities of the spline joint.
Устройство работает следующим образом .The device works as follows.
Колпачок 3 напрессовывают на винт 2 холостого хода при сборке карбюратора таким образом, чтобы имелась возможность регулировать состав смес на испытательном стенде посредством шлица дл инструмента на торце колпака . После окончательной регулировкиThe cap 3 is pressed onto the idling screw 2 during the assembly of the carburetor so that it is possible to adjust the composition of the mixture on the test bench by means of the slot for the tool on the end of the cap. After final adjustment
холостого хода на автомобиле с выставлением необходимого уровн СО в отработавших газах производ т фиксацию винта 2 холостого хода посредством нажати инструментом, которым производилась регулировка на торец колпачка 3. При этом колпачок 3 перемещаетс вдоль оси г оловки винта 2 Q холостого хода, заполн полость 7. Шлицы 4 на колпачке вход т в зацепление с шпицами 6 гнезда 5, обеспечива надежную фиксацию винта холостого хода.idling the car with setting the required level of CO in the exhaust gases, fixing the screw 2 of the idling by pressing the tool that was used to adjust the end of the cap 3. In this case, the cap 3 moves along the axis of the tip of the screw 2 Q of idling, filling the cavity 7. The splines 4 on the cap are engaged with the spitz 6 of the socket 5, ensuring a secure idle screw.
