Abstract (en)
[origin: EP1967727A2] An automotive fuel injection assembly (1) has a needle (4) that rises and falls within a jet (3) housing (2) to open and close a jet (5). A valve regulates the needle motion by side contact with a pressure pin (8). The needle (7) end geometry makes contact with the needle valve seat (9) but leaves an aperture that dampens fluid flow to the valve needle (7).
