Abstract (en)
The valve (110) has two magnet actuators (132, 134) and a spring (126) for interacting with a control member (124) in force directions that are opposite to each other. The spring is designed as a recoil spring (128) and arranged such that the valve is in a closed condition by the magnet actuators, without force. The recoil spring is designed such that the spring exercises closing force on the control member. The magnet actuators comprise an anchor (130) and two solenoid coils (136, 138), where the anchor is arranged between the solenoid coils. An independent claim is also included for a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine.
Abstract (de)
Es wird ein hydraulisches Ventil (110) für den Einsatz in einem Kraftstoffinjektor (112) zum Einspritzen eines Kraftstoffs in einen Brennraum einer Brennkraftmaschine vorgeschlagen. Das hydraulische Ventil (110) umfasst mindestens ein Stellglied (124) sowie weiterhin mindestens einen ersten Magnetaktor (132) und mindestens einen zweiten Magnetaktor (134). Der erste Magnetaktor (132) und der zweite Magnetaktor (134) sind eingerichtet, um mit einander entgegengesetzten Kraftrichtungen auf das Stellglied (124) einzuwirken.
