Abstract
(DE)
Die Erfindung betrifft ein Einspritzventil (1) für ein Wassereinspritzsystem eines Verbrennungsmotors, umfassend eine ringförmige Magnetspule (2) zur Einwirkung auf einen hubbeweglichen Anker (3), der mit einem Ventilglied (4) verbunden ist, ferner umfassend einen hohlzylinderförmigen Kern (5), der zumindest abschnittsweise von der Magnetspule (2) umgeben ist und einen Einlassstutzen (6) ausbildet oder mit einem Einlassstutzen (6) verbunden ist, über den das Einspritzventil (1) mit Wasser aus einer Verteilerleitung (7) versorgbar ist. Erfindungsgemäß ist in den Einlassstutzen (6) ein Körper (8) eingesetzt, der in axialer Richtung von einem Strömungskanal (9) durchsetzt ist, der eine Einlassöffnung (10) zur Versorgung des Einspritzventils (1) mit Wasser aus der Verteilerleitung (7) definiert. Die Erfindung betrifft ferner ein Wassereinspritzsystem für einen Verbrennungsmotor mit einem erfindungsgemäßen Einspritzventil (1).
(EN)
The invention relates to an injection valve (1) for a water injection system of an internal combustion engine, comprising an annular magnetic coil (2) for acting on an armature (3) which can be moved in a stroke-like manner and is connected to a valve member (4), further comprising a hollow cylindrical core (5) which is enclosed at least in portions by the magnetic coil (2) and forms an inlet nozzle (6) or is connected to an inlet nozzle (6), via which the injection valve (1) can be supplied with water from a distributor line (7). According to the invention, a body (8) is inserted in the inlet nozzle (6), which body is penetrated in the axial direction by a flow channel (9) which defines an inlet opening (10) for supplying the injection valve (1) with water from the distributor line (7). The invention further relates to a water injection system for an internal combustion engine having an injection valve (1) according to the invention.

L'invention concerne une soupape d'injection (1) pour un système d'injection d'eau d'un moteur à combustion interne, comprenant une bobine magnétique (2) annulaire servant à agir sur un induit (3) pouvant effectuer un mouvement de levage, qui est relié à un organe (4) de soupape, comprenant en outre un noyau (5) en forme de cylindre creux, qui est entouré au moins par endroits par la bobine magnétique (2) et réalise une tubulure d'admission (6) ou est relié à une tubulure d'admission (6), par l'intermédiaire de laquelle la soupape d'injection (1) peut être alimentée en eau provenant d'un conduit de distribution (7). Selon l'invention, un corps (8) est inséré dans la tubulure d'admission (6), lequel est traversé dans une direction axiale par un canal d'écoulement (9), qui définit une ouverture d'admission (10) servant à alimenter la soupape d'injection (1) en eau provenant du conduit de distribution (7). L'invention concerne en outre un système d'injection d'eau pour un moteur à combustion interne comprenant une soupape d'injection (1) selon l'invention.
