Patent ID: 8727242

Claim:
An injector for introducing fuel into a combustion chamber, the injector comprising: an injector body including— a base portion configured to receive fuel into the body; and a nozzle portion coupled to the base portion, wherein the nozzle portion is configured to be positioned proximate to the combustion chamber for injecting fuel into the combustion chamber; a valve carried by the body, wherein the valve is movable between a closed position and an open position to introduce fuel into the combustion chamber; and a valve operator assembly, the valve operator assembly including— a valve actuator operably coupled to the valve and positioned to move the valve to the open position; and an acoustical force modifier positioned adjacent the valve actuator and moveable to contact the valve actuator to induce vibrations in the valve actuator and the valve wherein the acoustical force modifier is a first acoustical force modifier, and wherein the valve operator assembly further includes a second acoustical force modifier positioned adjacent the valve actuator, the second acoustical force modifier operable to impart linear motion to the valve actuator and the valve.
