Title: FUEL INJECTION VALVE
Abstract:
A fuel injection valve (20) is provided with: a body (22) that forms a cylinder shape and has a sack chamber (27) at a distal end section as well as injection holes (28) extending from the sack chamber; and a valve element (30) provided within the body so as to be movable in a reciprocating manner. When the valve element is released from a state of being seated on an inner peripheral surface of the body, fuel is injected from the injection holes. The valve element has penetrating passages (36) extending in the axial direction thereof. Passage entrances (36a) of the penetrating passages are provided in the valve element further downstream than a seat section (34a) that sits on the inner peripheral surface of the body and further upstream than the sack chamber.
