Abstract (en)
[origin: EP0348786A2] In a fuel-injection valve with a minimum of two nozzle apertures (21, 21', 21'') in the base of an internal chamber (20, 20', 20'') which is enclosed by the valve seat (19, 19', 19'') and whose depth = 1/4 of the inside diameter of the valve seat (19, 19', 19''), this internal chamber (20, 20', 20'') has a very small "dead volume". To protect the nozzle apertures (21, 21', 21'') from deposits an outer chamber (24, 24', 24'') with an outlet aperture is post-connected to these. <IMAGE>
