Abstract

Использование: двигателеетроение. Сущность изобретени : у топливовпрыскивающего насоса высокого давлени  двигател  внутреннего сгорани  нижн   часть накидной гайки 6 расположена в проточке , выполненной в верхней части корпуса 1. а между торцами ступеней накидной гайки 5 и нажимного штуцера 5 установлен упорный подшипник 7. В таком насосе ИУТЫ, обеспечивающие уппотне ние стыков между плунжерной парой, седлом 3 нагнетательного клапана 4 и нажимным штуцером 6, действует в осевом направлении. Поэтому корпус 1 насоса не испытывает радиальных усилий. 1 илUsage: engine. SUMMARY OF THE INVENTION: for a high-pressure fuel injection pump of an internal combustion engine, the lower part of the union nut 6 is located in a groove made in the upper part of the housing 1. and the thrust bearing 7 is installed between the ends of the steps of the union nut 5 and the pressure fitting 5. the joints between the plunger pair, the seat 3 of the discharge valve 4 and the pressure fitting 6, acts in the axial direction. Therefore, the housing 1 of the pump does not experience radial forces. 1 silt
