#CMT# #/CMT# The valve (16) has magnets (18) including an anchor plate (26) that is accommodated at a pressure-balanced needle shape valve unit (30) that opens or closes a flat valve seat (42). The anchor plate is provided with a set of passage openings (74). The passage openings exhibit a diameter of 0.1 millimeter (mm), and are formed at the anchor plate. The passage openings are distributed in concentric circles, and are radially arranged above the anchor plate. The anchor plate exhibits a slot (50) for reduction of eddy currents, and is provided with a passage channel (66). #CMT#USE : #/CMT# Fast switching solenoid valve for actuation of a fuel injector that is utilized for injecting fuel to a combustion chamber of a self-ignited internal combustion engine. #CMT#ADVANTAGE : #/CMT# The anchor plate is provided with the passage openings, thus enabling complete dethrottling of the anchor plate for fuel injectors in a short switching time, and realizing maximum magnetic force and applying force to the valve. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of a completely dethrottled solenoid valve, which is pressure-balanced. 10 : Fuel injector 16 : Fast switching solenoid valve 18 : Magnets 26 : Anchor plate 30 : Valve unit 42 : Flat valve seat 50 : Slot 66 : Passage channel 74 : Passage openings. |
