摘要： An object of the invention is to provide a depressurizing valve mounted to a common rail for a fuel injection device, in which a direction of a connector for the depressurizing valve can be adjusted, without affecting an air gap and a sealing performance. The depressurizing valve has a valve unit and a coil unit which is detachably assembled to the valve unit by a mounting member, such as a retaining nut. A valve housing has an inside space, which is fluid tightly separated into first and second spaces by a connecting member, which is fluid tightly connected to the valve housing and a stator core. A valve body and a spring are arranged in the first space for closing a flow control port. A cylindrical coil is accommodated in the second space, such that the coil is rotatable with respect to the valve housing.

摘要： An electromagnetic fuel injection valve in which a first resin-molded layer that is made of a synthetic resin, covers a solenoid section, and forms a coupler main portion that defines a coupler is covered by a second resin-molded layer different from that of the first resin-molded layer so that an outer face of the coupler main portion is exposed from a middle part up to the extremity of the coupler main portion. An endless engagement groove is provided on the outer periphery of the middle pad of the coupler main portion of the first resin-molded layer, the second resin-molded layer engaging with the endless engagement groove. An extending portion extending further outward than the engagement groove is formed in the second resin-molded layer so that the extending portion makes contact with an outer face of the coupler main portion when in a non-engaged state and covers the coupler main portion.

摘要： A fuel injector includes first and second electrical actuators positioned within an injector body. First and second pairs of electrical conductors extend from a socket connector outside of the injector body to the first and second electrical actuators, respectively. The electrical conductors extend through an elastomeric sealing member that seals against fuel leakage from the fuel injector. The elastomeric sealing member provides annular sealing ridges in sealing contact with an access passage of the injector body and includes individual conductor seal passages that form seals around the outer surface of the individual electrical conductors. The elastomeric sealing member includes features that facilitate assembly of the fuel injector in a manner that reduces risk of damage to the sealing strategy.

摘要： A fuel injector for an internal combustion engine is provided which has a fuel supply path and a nozzle chamber. The fuel supply path extends a spray hole. The nozzle chamber is defined in the fuel supply path. A nozzle is disposed within the nozzle chamber to establish or block a fluid communication between the fuel supply path and the spray hole. A fuel pressure sensor is installed in the fuel injector so as to be exposed to the fuel in the nozzle chamber. Specifically, the fuel pressure sensor is located closer to the spray hole than a prior art structure in which the fuel pressure sensor is installed in a fuel supply pipe, thus resulting in increased accuracy in measuring a change in pressure of the fuel arising from the spraying of the fuel from the spray hole.
