Description
(54) НАСОС ДЛЯ ПОДАЧИ ТОПЛИВА В ДВИГАТЕЛЬ ВНУТРЕННЕГО СГОРАНИЯ(54) PUMP FOR FILLING OIL IN INTERNAL COMBUSTION ENGINE
1one
Изобретение нредназначено дл впрыска тонлива в двигатель внутреннего сгорани , преимущественно дизельный, автотракторного типа.The invention is intended for the injection of fuel into an internal combustion engine, mainly diesel, autotractor type.
Известны насосы, содержащие гильзу с плунжером, хвостовик которого снабжен п той и лысками, сопр женными с поворотным элементом, выполненным в виде зубчатых шестерен .Pumps are known that have a sleeve with a plunger, the shank of which is provided with tailings and flats associated with a rotatable element made in the form of gears.
Однако сборка таких насосов затруднена в результате ограниченности габаритов корпуса насосов автотракторных дизелей.However, the assembly of such pumps is difficult as a result of the limited dimensions of the pump casing of automotive diesel engines.
Цель изобретени - упростить изготовление и сборку насоса.The purpose of the invention is to simplify the manufacture and assembly of the pump.
Дл этого нужно обеспечить выемку плунжера через гильзу и его сопр жение с поворотным элементом съемного типа.To do this, it is necessary to provide the recess of the plunger through the sleeve and its interface with the rotatable element of the removable type.
Поворотный элемент в предложенном насосе выполнен в виде втулки, на боковой поверхности которой предусмотрен паз, щириной не менее рассто ни между плоскост ми лысок.The rotary element in the proposed pump is designed as a sleeve, on the side surface of which a groove is provided, with a width not less than the distance between the planes of the bald spots.
Па фиг. 1 изображен плунжер предложенного насоса; на фиг. 2 - плунжер в сборе сPa figs. 1 shows the plunger of the proposed pump; in fig. 2 - plunger assembly with
поворотным элементом; на фиг. 3 - поворотный элемент в виде втулки с пазом щириной А.a pivot element; in fig. 3 - rotary element in the form of a sleeve with a groove shchirinoy A.
Плунжер 1 имеет хвостовик 2 с лысками (А - рассто ние между плоскост ми). П та плунжера 3 имеет диаметр, меньший внутреннего диаметра гильзы, обхватывающей плунжер 1.The plunger 1 has a shank 2 with flats (A is the distance between the planes). The fifth of the plunger 3 has a diameter smaller than the internal diameter of the liner surrounding the plunger 1.
При сборке плунжер пропускают через гидьзу , и на хвостовик (см. фиг. 2) надевают втулку 4 через боковой паз 5, ширина которого равна или больше А.When assembling the plunger is passed through gidzu, and on the shank (see Fig. 2) put the sleeve 4 through the side groove 5, the width of which is equal to or greater than A.
Предмет изобретени Subject invention
Пасос дл подачи топлива в двигатель внутреннего сгорани , например дизель, содержащий гильзу с плунжером, хвостовик которого снабжен п той и лысками, сопр женными с поворотным элементом, отличающ и и с тем, что, с целью упрощени изготовлени и сборки, поворотный элемент выполнен в виде втулки, на боковой поверхности которой предусмотрен паз, шириной не менее рассто ни между плоскост ми лысок.Pasos for supplying fuel to an internal combustion engine, such as a diesel, contains a liner with a plunger, the shank of which is equipped with a heel and a flush, coupled with a pivot element, which is distinguished by the fact that, in order to simplify manufacture and assembly, the pivoting element is A sleeve, on the side surface of which a groove is provided, with a width not less than the distance between the planes of the bald spots.
