Title (EN) INJECTOR FOR A COMBUSTION ENGINE
(FR) INJECTEUR POUR MOTEUR À COMBUSTION
Abstract:
(EN) An injector (30) for a combustion engine comprises a pole piece (3), an armature (5), a valve needle (7) and a guiding element (9) with a guiding portion (11) which is in sliding contact with the pole piece (3). Respective penetrating openings (13, 19) of the pole piece (3) and the guiding element (9) provide a fluid channel for the fluid along a longitudinal axis (L) of the injector (30). The valve needle (7) is arranged axially moveable along the longitudinal axis (L) to prevent or enable a fluid flow. The guiding element (9) is releasably coupled to the valve needle (7) to realize a guidance of the valve needle (7) along the longitudinal axis (L).
(FR) Selon l'invention, un injecteur (30) pour un moteur à combustion comprend une pièce polaire (3), une armature (5), un pointeau de soupape (7) et un élément de guidage (9) avec une partie de guidage (11) qui est en contact coulissant avec la pièce polaire (3). Des ouvertures pénétrantes respectives (13, 19) de la pièce polaire (3) et de l'élément de guidage (9) créent un canal de fluide pour le fluide le long d'un axe longitudinal (L) de l'injecteur (30). Le pointeau de soupape (7) est agencé axialement de façon à être mobile le long de l'axe longitudinal (L) pour empêcher ou permettre un écoulement de fluide. L'élément de guidage (9) est accouplé de manière libérable au pointeau de soupape (7) pour réaliser un guidage du pointeau de soupape (7) le long de l'axe longitudinal (L).
