Definitions

  • This pressure surge can lead to the closing part being lifted from its seat and that a refilling process of the pump work space can now take place briefly via the suction line.
  • This quantity flowing into the pump work space can continue to be injected during the next delivery stroke of the pump piston and the purpose of the solenoid valve serving to shut off is therefore not achieved.
  • the internal combustion engine can fail.
  • the solenoid valve according to the invention with the characterizing features of the main claim has the advantage that an opening of the closing part and thus a correspondingly large fuel flow to the pump work space is prevented, since the pressure surge via the opening valve member, which releases only a small overflow cross section, is reduced.
  • the pump piston During the respective suction strokes of the pump piston, it sucks fuel from the pump suction chamber 11 via the filling groove 8, which is then covered with the suction line, so that the pump working chamber 6 is filled with fuel at the beginning of the following delivery stroke.
  • the ring slide 17 In the load position, the ring slide 17 then closes the outlets of the transverse bore 19 so that during the subsequent delivery stroke of the pump piston and after the filling groove has been closed again in the pump
  • the fuel is brought to high pressure, which is then fed via the longitudinal channel 20 and one of the injection lines 23 to the corresponding fuel injection valve and is injected.

Abstract

Une électrovanne servant à la coupure d'une conduite d'aspiration de carburant (10) pour l'alimentation en carburant d'un espace de travail d'une pompe d'injection de carburant, présente sur la partie de fermeture (28) un trou (50) entrant par le devant et pouvant être obturé au moyen d'un élément de soupape (61) sous l'effet d'un ressort de fermeture (57). En présence d'à-coups de pression dans le tronçon de la conduite d'aspiration (31) obturée par la partie de fermeture (28) et menant vers l'espace de travail de la pompe, la partie de fermeture (28) et toute la section de la partie de la conduite d'aspiration (31) ne s'ouvrent pas, mais uniquement la section du trou (50). Ce trou, après avoir été ouvert, est rapidement refermé par l'élément de soupape (61) à faible masse, de façon que seulement de faibles quantités de carburant puissent passer à travers le trou (50) en vue de l'égalisation de pression.
