Definitions

  • the injectors are said to improve noise, etc. can be switched quickly at high injection pressures.
  • high storage pressures when using a solenoid valve a pre-injection difficult because the switching times of the Solenoid valve are too long and the full stroke of the valve must be run through so that reproducible conditions, for example the injection quantity can be achieved.
  • the formation of the injection rate i.e. slow opening, however, quickest closing of the nozzle needle, the shaping the injection rate according to a map can hardly be possible.
  • the illustration shows a 2/2-way valve with piezo actuator.
  • the injector shown in the illustration consists of a elongated housing 6, on the lower end of which Union nut 3 is screwed on. With this cap nut 3 is an intermediate plate from the lower end of the housing 6 4 and a nozzle body 1, in which a nozzle needle 2 is kept. Both the washer 4 and the nozzle body 1 have a central bore 35 in which the nozzle needle 2 guided in the axial direction is.
  • the nozzle needle lies at the end in the drawn state 2 on an annular nozzle seat 36, in the area thereof Nozzle holes 37, 35 are provided which are the nozzle needle 2 closes.
  • the nozzle needle 2 with one Provide pressure pin 5, which is provided in a housing 6
  • Spring chamber 30 is arranged and one in the spring chamber 30 arranged nozzle spring 7 is acted on, so that the Nozzle needle 2 slightly biased towards the nozzle seat 36 and closes it.
  • the other end of the Nozzle spring 7 lies on the pressure bolt 5 opposite End of the spring chamber 30, with a shim in between 9 for setting the nozzle spring preload is arranged.
  • a small spring 17 is provided between an inner surface of the primary piston 19 and the Secondary piston 39 is arranged and the valve needle 27 presses a valve seat 40 which is connected to a secondary throttle 32 communicates.
  • the secondary choke 32 stands with the first pressure chamber 11 in connection, which also has a Primary throttle 14 and a bore 13 with the high pressure standing fuel inlet 11 is connected.
  • the Fuel inlet 12 is provided via an inlet bore 10 a second pressure chamber 41 in connection, which by a Recess is formed in the housing 6 in the area of the nozzle needle 2 is, the nozzle needle in this area stepwise is set off, so that thereby control surfaces for the nozzle needle 2 are formed.
  • the temperature compensation or the basic position of the valve is over defined column between valve needle 27 and Primary piston 19 and between primary piston 19 and secondary piston 27 reached.
  • the return 25 remains on Injector always applied with a low pressure.

Abstract

L'invention concerne une soupape d'injection pour systèmes d'injection de carburant, qui comprend une aiguille d'injection (2) placée dans un corps de soupape (1), une arrivée de carburant (12), ainsi qu'un dispositif de commande. L'invention vise à ce que le taux d'injection puisse être régulable de manière précise. A cet effet, il est prévu une chambre de pression (11) qui est reliée à l'arrivée de carburant (12) par l'intermédiaire d'un étranglement primaire (14), ainsi qu'à une chambre de décharge (31) par l'intermédiaire d'un étranglement secondaire (32).

Claims (5)

  1. Injecteur pour système d'injection de carburant, comportant:
    une aiguille d'injection (2) disposée dans un carter d'injecteur (1), qui est sollicitée par un ressort d'injecteur (7) contre un siège d'injecteur (36), et qui peut ouvrir et fermer au moins un orifice d'injecteur (37, 38),
    une arrivée de carburant (12), qui est reliée, par une première chambre sous pression (11), à une première surface de commande, et, par une deuxième chambre sous pression (41), à une deuxième surface de commande de l'aiguille d'injection (2), une pression sur la première surface de commande appliquant l'aiguille d'injection (2) sur le siège d'injecteur associé (36) et une pression sur la deuxième surface de commande levant l'aiguille d'injection (2) du siège d'injecteur (36),
    un dispositif d'actionnement, qui commande une aiguille d'injection (27) pour décharger de la pression la première surface de commande en vue de commander l'injection de carburant,
    la première chambre sous pression (11) étant reliée à l'arrivée de carburant (12) par un ajutage primaire (14), et, par un ajutage secondaire (32), à une chambre de détente (31),
       caractérisé en ce que
    le dispositif d'actionnement comporte un actionneur piézo-électrique (20), qui commande, au moyen d'un dispositif de transformation hydraulique (19), l'aiguille d'injection (27) commandant le passage au travers de l'ajutage secondaire (32), et
    en ce qu'entre l'aiguille d'injection (27) et le carter d'injecteur (1), ainsi qu'entre un piston primaire (19), présentant le dispositif d'actionnement, et un piston secondaire (39), ainsi qu'entre le piston primaire (19) et le carter d'injecteur (1), sont prévus des interstices au travers desquels peut se produire une faible fuite, ce qui a pour effet qu'une chambre de travail (28) est toujours remplie de fluide, et que, lors de dilatations thermiques, l'actionnement de commande piézo-électrique a une position initiale rattrapant les jeux, soumise à une précontrainte de pression, et définie de façon univoque.
  2. Injecteur suivant la revendication 1, caractérisé en ce que l'actionneur (20) est au contact d'un piston primaire (19),
    en ce qu'un piston secondaire (39) est guidé dans le piston primaire (19), en ce que le piston primaire (19), le piston secondaire (39) et le carter d'injecteur (1) délimitent une chambre de travail (28),
    en ce que la chambre de travail (28) est remplie de liquide, de façon, lorsque le piston primaire (19) se déplace, à faire déplacer le piston secondaire (39) dans le sens opposé au mouvement du piston primaire (19),
    en ce que le piston secondaire (39) est relié à l'aiguille d'injection (27) qui est en contact avec un siège d'injecteur (40),
    en ce que lorsqu'il se produit une déformation de l'actionneur piézo-électrique (20), le piston secondaire (39) se déplace dans le sens opposé au piston primaire (19), et l'aiguille d'injection (27) se soulève du siège d'injecteur (40), de telle façon que l'ajutage secondaire (15) s'ouvre.
  3. Injecteur suivant la revendication 1, caractérisé en ce que la chambre de détente (31) est réalisée sous la forme d'un autre ajutage.
  4. Injecteur suivant la revendication 1, caractérisé en ce que les ajutages primaire (14) et secondaire (32) sont dimensionnés de telle façon que le débit volumique de carburant, se réglant au moment de l'ouverture de l'aiguille d'injection (27) et traversant l'ajutage secondaire (32), soit plus grand que celui traversant l'ajutage primaire (14).
  5. Injecteur suivant la revendication 1, caractérisée en ce que l'aiguille d'injection (27) est réalisée sous la forme d'une vanne à siège, qui règle le degré de l'ouverture de l'ajutage secondaire (32), située à l'opposé de la chambre sous pression (11).
