FIELD: engines and pumps.SUBSTANCE: invention can be used in internal combustion engines. The invention proposes a high-pressure fuel pump of an accumulator fuel system of an internal combustion engine, which includes housing 1, in which there arranged is plunger 2, flat pusher 3 with support end surface 5 and external cylindrical guide surface 4, a drive eccentric shaft provided with eccentric 6 and intermediate sleeve 7 having an external cylindrical surface and installed in a movable manner on the eccentric, with that, the external cylindrical surface of the intermediate sleeve contacts the support surface of the pusher. Besides, the support end surface of the pusher has an incidence to the plane perpendicular to the axis of the cylindrical surface of the pusher; with that, an incidence angle has the value of 0.05-6°.EFFECT: increase of carrying capacity and service life of a drive of plunges of the fuel pump.3 cl, 6 dwg |
