FIELD: motors and pumps.
SUBSTANCE: invention can be used in fuel supply systems of internal combustion engines (ICE). Proposed valve (10) fuel injection has an intermediate valve, intermediate valve element (78) which is made in the form of a mushroom. Shank (76) of intermediate valve element (78) with a tight sliding fit is installed in guide passage (74) of intermediate part (66). Shank (76) and head (80) of intermediate valve element (78) and intermediate part (66) are limited to annular space (120), into which supply (86) of the high pressure falls and which is formed by inner annular space (108), as well as shielded annular space (118). Gap annular space (118) is bounded by head (80) and intermediate part (66), as well as radially outside sealing lip (112). Adhesion force between intermediate valve element (78) and intermediate part (66), which counteracts the opening movement of injection valve element (56), is minimized.
EFFECT: fuel injection valve is proposed.
