Abstract (en)

[origin: WO9612104A1] Significant improvement in limiting the dispersion of an injected fuel stream is obtained by constructing the tip end of the needle valve (21) to have a proximal portion and a distal portion wherein the proximal portion is a surface (52) in the form of a segment of an imaginary sphere that is geometrically defined by imaginary spaced-apart, parallel planes passing through such imaginary sphere, that surface of the proximal tip portion being that portion of said tip end that seats on and unseats from a frustoconical seat (32) as the valve is reciprocated, and the distal tip portion (56) is a frustoconical surface (54) extending tangentially from the proximal tip portion. Such limiting of the dispersion of the injected stream provides better targeting of the injected fuel.
