Definitions

  • the nozzle comprises a holder 10 which is of generally cylindrical form and which is provided with a lateral extension 11 having a threaded aperture which receives a pipe union 12 which constitutes the fuel inlet for the nozzle.
  • a valve body 13 which is of stepped cylindrical form.
  • the narrower end portion of the valve or nozzle body projects in use, through the wall of a combustion space of an engine and the nozzle body is retained relative to the holder in known manner, by a cup shaped retaining member 14 having an aperture formed in its base wall through which the narrower portion of the nozzle body extends.
  • the layers 35 and 41 may be formed by locating the members within the sleeves in the desired spaced relationship and introducing the ceramic material into the gap between the presented surfaces.
  • the ceramic is subjected to a thermo-chemical treatment the effect of which is to form a molecular bond with the metal of the member and sleeve to thereby secure the two members together. After bonding the sleeve can be machined to the desired diameter and the profile 31 established.

Abstract

Un gicleur d'injection de carburant possède un élément de soupape (16) coulissant dans un alésage (15) situé dans le corps du gicleur (13). L'élément de soupape possède un profil d'extrémité (31) dont la forme lui permet de s'introduire dans un logement situé à l'extrémité de l'alésage. L'élément de soupape possède un noyau allongé (30), conducteur d'électricité, dont l'une des extrémités définit le profil (31) et qui est entouré par une gaine métallique (34), avec un espacement intermédiaire, guidant le déplacement de l'élément de soupape dans l'alésage. La gaine adhère au noyau au moyen d'une couche (35) d'un matériau d'isolation électrique, de préférence une céramique, qui assure l'isolation électrique entre l'élément allongé et le corps du gicleur, sauf quand l'élément de soupape est en position fermée.
