Title
(EN) FUEL INJECTOR WITH ELECTROMAGNETICALLY AUTONOMOUS SUBASSEMBLY
(FR) INJECTEUR DE CARBURANT A SOUS-ENSEMBLE AUTONOME SUR LE PLAN ELECTRIQUE
Abstract
(EN)
The fuel injector comprises a solenoid (9), wound around a bobbin (3), which can be energized through electrical connections (10), a guideless magnetic valve member (7), a valve seat (6), a magnetic core (5), at least one magnetic coupling element (2), a fuel inlet tube (8) and an external housing (1). The guideless magnetic valve member (7), the valve seat (6), the magnetic core (5), the at least (1) magnetic coupling element (2), the solenoid (9), the bobbin (3) and the electrical connections (10) form an electromagnetically autonomous subassembly which comprises the entire magnetic circuit and also all the electrical components of the finished injector. The solenoid (9) and bobbin (3) are lodged in a space defined between the at least one magnetic coupling element (2) and the magnetic core (5), and the subassembly is possibly tested and calibrated extensively prior to the obtention of the finished fuel injector.
(FR)
Cet injecteur de carburant comprend un électro-aimant (9) enroulé autour d'une bobine (3) qui peut être excité par l'intermédiaire de connexions électriques (10), un élément de vanne électromagnétique (7) sans élément de guidage, un siège de vanne (6), un noyau magnétique (5), au moins un élément de couplage magnétique (2), un tube d'admission (8) de carburant ainsi qu'un boîtier externe (1). L'élément de vanne électromagnétique (7) sans élément de guidage, le siège de vanne (6), le noyau magnétique (5), l'élément ou les éléments de couplage magnétique (2), l'électro-aimant (9), la bobine (3) et les connexions électriques (10) constituent un sous-ensemble autonome sur le plan électromagnétique qui comprend la totalité du circuit magnétique ainsi que tous les composants électriques de l'injecteur fini. L'électro-aimant (9) et la bobine (3) sont logés dans un espace défini entre l'élément ou les éléments de couplage magnétique (2) et le noyau magnétique (5), le sous-ensemble étant éventuellement mis à l'essai et étalonné à plusieurs reprises avant l'obtention de l'injecteur de carburant fini.
