Abstract (en)

[origin: US4785787A] A fuel injection system for a diesel engine in which an electromagnetically actuated valve determines the initiation and conclusion of injection. A valve of this sort consists of a primary slide valve component 3 which, in its closed position, makes a seating engagement with a tapered valve seat 5 to close a connecting channel 16 between the injection line 10 and a dumping passage 12. The primary valve component is moved to its open position by an electromagnetically actuated impact bolt 40. In order to avoid problems associated with seat valves, a second electrically operated valve component 6 is provided in a second connecting channel 25 between the high pressure channel 7 and the dumping channel 12.
