FIELD: engines and pumps.
SUBSTANCE: invention can be used in fuel injection systems of internal combustion engines (ICE). Proposed is a fuel pump comprises housing 11 of the pump, cylinder head 12, plunger 13 arranged able to move in guide hole 12a of the cylinder head, plunger pusher 18, camshaft 21 arranged able to rotate in the cam mechanism chamber, cam 20 made integral with the camshaft, and return spring 15 of the plunger. Pusher 18 of the plunger has cylindrical housing 16 and roller 17, and in cavity 11a of the cylinder there is cylindrical guide ring 26 fixed. Housing 16 of the pusher and cylindrical part of guide ring 26 have guide sections 26a and 16a coupled in the axial direction and located in at least two points divided in equal intervals.
EFFECT: more uniform contact of the plunger pusher with the cylinder wall and increased service life of the fuel pump.
