FIELD: engine engineering. SUBSTANCE: sealing collar of the fuel pump is a ring that goes into a bushing with the sharp edge at the place where it abuts against the plunger. The inner bottom of one of the caps under the sealing collar is conical and has a thickening in the direction to the plunger. A plate spring is interposed between the sealing collar and the other cap. The outer diameter of the plate spring is conjugated with the outer diameter of the collar. The collar is made, e.g. of a fluoroplastic. EFFECT: enhanced reliability. 3 dwg
