Definitions

  • Such a delay of the lowering of the pressure in the control chamber of the first valve can be realized, for example, via an interposition of a throttle element in a line which connects the return to said control chamber. It is particularly advantageous in such a context to control the control chamber of the injection nozzle by means of the second valve via the same output, which is connected to the first valve.

Abstract

L'invention concerne un dispositif d'injection d'un carburant dans une chambre de combustion d'un moteur à combustion interne, ledit dispositif comprenant une source de pression (2), un amplificateur de pression (3), un injecteur (4), une première soupape (5) permettant de réduire une pression dans une chambre différentielle (11) de l'amplificateur de pression (3), une deuxième soupape (6) permettant de remplir la chambre différentielle (11) de carburant du premier niveau de pression de la source de pression (2), ainsi qu'une chambre de commande (13) de la première soupape (5) pouvant être commandée par la deuxième soupape (6). L'invention vise à augmenter le rendement d'un tel dispositif et à permettre d'obtenir des temps de commutation réduits. A cet effet, toutes les conduites (conduite (43), conduite (50), section transversale d'évacuation (35)) menant à la première soupape (5) peuvent être séparées au moins temporairement de la source de pression (2).
