Abstract
A fuel injector for a multi-cylinder internal combustion engine in which a single fuel injector meters fuel to a plurality of injection nozzles which discharge fuel adjacent to the engine inlet ports having a distributor with an outlet passage and a valve seat surrounding the passage, a single valve engaging the valve seat to control fuel delivery through the passage and a valve actuator adapted to pivotally displace the valve from the seat to contact a valve stop to allow fuel delivery through the passages. The stop surface comprises the lower surface of the valve body which houses the actuator and the center pole of the actuator. The center pole of the actuator extends beyond the lower surface of the body to provide a non-plannar valve stop surface which makes point contact therewith and avoids surface-to-surface contact between the members which may result in incidental adhesion therebetween.
