ABSTRACT:
A fuel injector assembly for a fuel injection system has a fuel pumping assembly with a fuel inlet and a fuel nozzle for causing fuel to be periodically pumped from the fuel inlet through the nozzle. The fuel injector assembly has an electro-hydraulic control valve associated with the fuel pumping means. The control valve comprises a housing, a first conduit formed in the housing and fluidly coupled to the fuel pumping means, a second conduit formed in the housing and fluidly coupled to a source of pressurized hydraulic fluid. A valve element is disposed in the housing and is reciprocable between a first position in which the first conduit is fluidly coupled to the second conduit and a second position in which the first conduit is fluidly isolated from the second conduit. The control valve also includes a pair of electrically energizable electromagnetic devices for controlling the reciprocation of the valve element. The components of the control valve are preferably composed of SAE 52100 steel so that the valve element remains latched in the first and second positions after electric current to the electromagnetic devices is turned off.
