Definitions

  • the peripheral wall of the spring retainer 36 is provided with a single slit 37 extending in the axial direction, whereby the spring retainer 36 can be elastically reduced in diameter.
  • the outer diameter of the spring retainer 36 is set to be larger than the inner diameter of the sleeve 38 in a free state in consideration of a press-fitting allowance for the hollow portion 36 of the sleeve 38.
  • the present invention is not limited to the embodiments described above, and various design changes can be made without departing from the scope of the invention.
  • the present invention can be applied to an injection valve for liquid fuel such as gasoline.

Abstract

L'invention concerne une soupape d'injection de carburant qui comprend : un arrêt (36) de ressort qui est disposé et apposé dans un noyau fixe (5) et qui comporte une section creuse servant de passage central (50) de carburant pour raccorder l'intérieur d'un cylindre (6) d'arrivée de carburant à l'intérieur d'un compartiment (3) de soupape ; et un ressort de rappel (33) qui est disposé en position comprimée entre un siège arrière (35) de ressort à l'extrémité avant de l'arrêt (36) de ressort et le siège avant (34) de ressort d'un noyau mobile (12) et qui presse un corps (13) de soupape vers un siège (7) de soupape. Un passage extérieur (51) de carburant qui raccorde l'intérieur du cylindre (6) d'arrivée de carburant à l'intérieur du compartiment (3) de soupape et qui s'étend parallèlement au passage central (50) de carburant est formé entre l'arrêt (36) de ressort et le noyau fixe (5). Grâce à cette configuration, on peut augmenter la section transversale du passage de carburant autour de l'arrêt de ressort sans compromettre la fonction de l'arrêt de ressort qui sert de siège pour le ressort de rappel.
