A method for adjusting the fuel injection quantity of an electromagnetic fuel injector having a needle valve, an electromagnetic actuator composed of a movable core which moves with the needle valve and a fixed iron core for attracting the movable core to move the needle valve to its open position, an adjust pipe inser...
An electronically controlled fuel supply system is provided for employing a plurality of fuel injectors which maximize SAC pressures under both low speed and high speed operating conditions and are capable of sustaining SAC pressures in excess of 30,000 psi. The fuel supply system of the present invention includes a ge...
A method for controlling a fuel injector provided with an electrically operated electomagnetic actuator in such a manner as to open the injector for a determined injection time; the method providing that the injector be operated with a first current waveform if the injection time is greater than a predetermined thresho...
A fuel injector includes an injector body with a tip component that defines at least one nozzle outlet. A needle valve member is positioned in the injector body and includes a frustoconical segment positioned in a frustoconical bore to separate a needle control chamber from a nozzle chamber. The needle valve member inc...
A valve includes a rotor and a stator. The rotor and the stator each have seal surfaces for contacting and sliding against one another during operation of the valve. Either or both of the rotor and the stator have a seal-surface coating formed by depositing an at least partially amorphous interlayer on a substrate and ...
An automatic injector dispenses a predetermined dose of medicament without a user having to manually force the needle into an injection site. The automatic injector includes a needle cover having a locked retracted position with respect to the injector housing prior to a medicament dispensing operation. The needle cove...
