Title (EN) CONTROL VALVE ARRANGEMENT
(FR) AGENCEMENT DE VANNE DE COMMANDE
Abstract:
(EN) A control valve arrangement (12) of a fuel injector (10) comprises a bore (18) in which a piston (16) is slidably arranged, the piston piloting injection events and the bore opening in direct and unrestricted fluid communication into a first control chamber (24). The arrangement comprises a further fluid communication path from a high pressure line (20) to a second control chamber (68), the further fluid communication path comprising, for example, a clearance, a channel or a bypass orifice.
(FR) L'invention concerne un ensemble vanne de commande (12) d'un injecteur de carburant (10), qui comporte un alésage (18) dans lequel un piston (16) est agencé de manière coulissante. Le piston (16) commande les événements d'injection, et l'alésage s'ouvre en communication fluidique directe et non restreinte dans une première chambre de commande (24). L'agencement comprend une autre voie de communication fluidique menant d'une conduite haute pression (20) à une seconde chambre de commande (68), ladite autre voie de communication fluidique comprenant, par exemple, un dégagement, un canal ou un orifice de dérivation.
