Abstract

Selon la présente invention, sachant que la direction dans laquelle se déplace une aiguille (2) est la direction axiale ; la direction dans laquelle se déplace l'aiguille (2) lorsque l'injection de carburant commence est le haut ; le point central d'une sphère ayant la surface sphérique d'une chambre formant sac (6) est le point central du sac (P1) ; une droite passant par le point central du sac (P1) dans la direction axiale est la ligne médiane du sac (L1) ; et une droite qui est obtenue en prolongeant l'axe central d'un trou de buse (3) jusque dans la chambre formant sac (6) est une ligne de prolongement de trou de buse (L2), la ligne de prolongement de trou de buse (L2) est prévue pour croiser la ligne médiane du sac (L1), et le point de croisement réel (JP2).According to the present invention, knowing that the direction in which a needle (2) is moving is the axial direction; the direction in which the needle (2) moves when fuel injection begins is up; the center point of a sphere having the spherical surface of a bag chamber (6) is the center point of the bag (P1); a line passing through the central point of the bag (P1) in the axial direction is the median line of the bag (L1); and a line which is obtained by extending the central axis of a nozzle hole (3) into the bag chamber (6) is a nozzle hole extension line (L2), the borehole extension line nozzle (L2) is provided to cross the median line of the bag (L1), and the actual crossover point (JP2).
