Изобретение относится к области двигателей внутреннего сгорания, снабженных топливными насосами для впрыска топлива, преимущественно маловязкого. С целью увеличения ресурса непрецизионного топливного насоса за счет увеличения срока службы уплотнительной манжеты и удешевления ее стоимости последняя имеет форму конического кольца, переходящего во втулку с острой кромкой в месте примыкания ее к плунжеру, внутреннее донышко одной из чашек под уплотнительной манжетой коническое, с утолщением в направлении плунжера, а между уплотнительной манжетой и другой чашкой размещена тарельчатая пружина, внешний диаметр которой сопряжен с внешним диаметром манжеты, причем последняя выполнена, например, из фторопласта. 3 ил.The invention relates to the field of internal combustion engines, equipped with fuel pumps for fuel injection, mainly low-viscosity. In order to increase the life of the non-precision fuel pump by increasing the service life of the sealing cuff and reducing its cost, the latter has the shape of a conical ring, which passes into a sleeve with a sharp edge at its junction with the plunger; the direction of the plunger, and between the sealing cuff and the other cup there is a cup spring, the outer diameter of which is associated with the outer diameter of the cuff, the latter being made, for example, from fluoroplastic. 3 il.
