摘要： A fuel injection valve comprises: a solenoid unit including a core, an armature and a coil; and a valve unit including a valve element connected to the armature to travel therewith, and a valve seat that regulates a movement in valve closing direction of the valve element, and is open and closed by the valve element separating from or coming in contact with the valve seat, and a stopper for regulating a movement in valve opening direction of the valve element, said valve unit being connected to the solenoid unit. There is provided a cavity that communicates with a gap formed between the core and the armature in opposition, and the cavity forms a resonator for suppressing bounce of the valve element. In spite of the simple structure, it is possible to effectively suppress bounce of the valve element that takes place at the time of valve opening/closing.

摘要： When a fuel injection valve is mounted on an engine, a distance between a core and an armature during non-energization of a coil can be prevented from becoming narrow. The coil is arranged inside the core, and a body is fixedly secured at its one end to an end of the core. A housing is arranged outside the coil with its one end abutting a cylinder head. A cap is arranged at the other end of the housing, and abuts at its side opposite to the housing with a fastening unit. The armature is arranged for reciprocation inside the body, and is magnetically attracted to the magnetized core. A gap is formed between the housing and the body, with the cap and the core being fixed to each other, and upon mounting the valve on the engine, the housing and the fastening unit abut the cylinder head and the cap, respectively.

摘要： A fuel injection valve includes a valve main body of a hollow tubular shape, a needle valve provided to the valve main body in a slidable manner, a valve seat opposing the needle valve to form a seat portion and having an injection hole formed downstream of the seat portion, and a guide portion provided upstream of the seat portion to guide the needle valve. An annular passage communicating in a circumferential direction is defined between the inner peripheral surface of the valve main body and the outer peripheral surface of the guide portion and a fuel passage through which to introduce a fuel from the annular passage to the seat portion is defined. An almost cylindrical filter to trap foreign matter heading toward the fuel passage is provided to the annular passage.

On the resultant signals, 2×2 channel processing unit performs 2×2 pseudo channel processing, thereby forming equivalent M×N channels.
