Patent ID: 6964263

Claim:
An electrically operated fuel injection apparatus comprising: a fuel intake means ( 110 ), a fuel pumping means ( 112 ) and a fuel injecting means ( 113 ), wherein the fuel introduced via the fuel intake means ( 110 ) is pumped by the fuel pumping means ( 112 ) and injected out from the fuel injecting means ( 113 ), wherein the fuel pumping means ( 112 ) includes a working coil ( 13 ), a return coil ( 12 ) and a follower ( 114 ) driven by the electromagnetic fields induced from said coils, and said follower ( 114 ) is driven forwardly by the electromagnetic loop formed by said working coil ( 13 ) to inject the fuel out from said fuel injecting means ( 113 ), and is returned by the electromagnetic loop formed by the return coil ( 12 ), said follower comprising an armature ( 56 ) and a plunger ( 46 ) with a central fuel channel ( 45 ) running through it, wherein said working coil ( 13 ) and the return coil ( 12 ) are arranged coaxially, and wherein said armature ( 56 ) and the plunger ( 46 ) are two separated components that are spaced apart from each other depending on actuation of the return coil ( 12 ) and working coil ( 13 ).
