Patent ID: 6935578

Claim:
A fuel injection valve for an in-cylinder injection type engine having a fuel swirling means for giving a swirling force at an upper stream of a valve seat to a fuel passage through a surrounding area of a valve body and a nozzle injecting a swirling fuel, wherein a fuel spray injected out from an injection port of said nozzle is so formed that an orientation of said fuel spray is deflected in a definite direction on a basis of a longitudinal axis of a fuel injection valve body, a reachable distance of said fuel spray at a deflected side is longer and a reachable distance of said fuel spray at another side opposite to a deflected side is shorter, said fuel swirling means being formed with a hole at the center portion thereof, said valve body extending to said seat surface formed on the valve seat surface through said hole, said fuel swirling means forming radial passage on a mating surface with said valve seat surface, said radial passage extending in tangential direction of said hole for supplying fuel from the outside to the inside.
