FIELD: engines and pumps.
SUBSTANCE: invention can be used in internal combustion engines (ICE) fuel injection systems. Disclosed is vehicle fuel supply jet pump (22), wherein in such jet pump nozzle (30) preliminary cleaning filter is formed, at that, between nozzle (30) and mounting cavity (36) wall channel (47, 50) is formed, which flow area is less than nozzle (30) outlet hole diameter.
EFFECT: jet pump design simplification and reduction of cost.
