ABSTRACT:
A solenoid-controlled fuel injection device, particularly useful for injecting non-Newtonian types of fuel materials, such as coal slurry, to a preburn chamber of an internal combustion engine, comprises a wet-type solenoid unit and a vortex valve unit integrated together in a modular configuration. The solenoid unit contains a magnetic coil surrounding a coaxial control fluid-sealing bore through which a cylindrical armature is translated. The armature has a coaxial armature stem which is engaged by the valve stem of the vortex valve unit. The vortex valve stem is supported on a compression spring within the longitudinal bore of a valve body, coaxial with the bore of the solenoid unit and engages a poppet valve seat adjacent to a vortex valve element. A control fluid supply inlet is coupled to the longitudinal bore, while a fuel supply bore is coupled to a fuel input port to the vortex chamber of the vortex valve. Until the coil is energized, the valve stem is spring-biased away from the valve seat, so that control fluid in the longitudinal bore is directed into the vortex chamber, to prevent fuel from being supplied from an outlet nozzle. When the coil is energized, the armature translates the valve stem against the spring bias, to contact the poppet seat and cut off control fluid to the vortex valve, whereby fuel is injected via the nozzle at the vortex chamber output port.
