ABSTRACT:
In an internal combustion engine with combustion chambers (CC'S) (538), a fuel injector (FI) comprising an outer shell (628) containing a fuel supply cavity (FSC) (530) having an openable valve (546) for storing fuel, a control body assembly (CBA) (520) within the outer shell (628). A rod (512) extends from FSC through CBA along the length of the outer shell with piston (518) formed thereon. An internal bore (534) extends therethrough from the side of a closed end of rod (512) which is movable into the FSC for carrying fuel from the FSC to the CC. A rod supporting base assembly (562), responsive to a predetermined CC pressure increase causes rod (512) to enter FSC, closing valve (546) to cease fuel from entering FSC and exposing bore (534) to force the pressurized fuel in the FSC down bore into the CC. Concentric open ended cylinders (OEC'S) (510) are positioned between the CBA and the base assembly with alternate OEC'S (514) secured to CBA and the other OEC'S (516) secured to base assembly (562). An E-R mixture between FSC and base assembly becomes solidified between the OEC'S when proper voltage is applied thereacross. The CBA responds to the fluid E-R mixture and a certain CC pressure to enable rod (512) to enter FSC, forcing fuel down rod bore (534) into the CC, and responsive to the solid E-R mixture to stop movement of rod (512), thereby stopping fuel flow down rod bore (534) into CC (538).
