Abstract
Топливоподкачивающий насос для двигателя внутреннего сгорания, содержащий корпус с рабочей полостью, сообщенный с линиями подвода и нагнетания топлива через всасывающий и нагнетательный клапаны соответственно, размещенный в рабочей полости нагнетающий поршень, свободно сопряженный с одной стороны со штоком роликового толкателя, а с другой с возвратной пружиной, крышку рабочей полости со стороны возвратной пружины и узел ручной прокачки топлива со штоком, поршеньком и элементами фиксации штока, отличающийся тем, что на рабочих торцах всасывающего и нагнетательного клапанов выполнены по меньшей мере два кольцевых выступа треугольной в сечении формы, расположенных концентрично, причем высота выступа большего диаметра больше высоты выступа меньшего диаметра, кроме того диаметры нагнетающего поршня и штока роликового толкателя связаны соотношением D2=2d2, где D - диаметр нагнетающего поршня, a d - диаметр штока роликового толкателя. A fuel priming pump for an internal combustion engine, comprising a housing with a working cavity in communication with fuel supply and discharge lines through the suction and discharge valves, respectively, a loading piston located in the working cavity, freely connected on one side to the roller follower rod, and on the other to a return spring , the cover of the working cavity from the return spring side and the manual fuel pumping unit with the rod, piston and rod fixing elements, characterized in that at the working ends the suction and discharge valves have at least two annular protrusions of a triangular cross-sectional shape arranged concentrically, and the height of the protrusion of a larger diameter is greater than the height of the protrusion of a smaller diameter, in addition, the diameters of the injection piston and the rod of the roller follower are connected by the ratio D2 = 2d2, where D is the diameter of the injection piston, ad - diameter of the rod of the roller pusher.
