Electromagnetic fuel injection valve

摘要

An electromagnetic fuel injection valve which exhibits faster opening and closing times as well as being more linear in flow characteristics than prior art valves. The fuel injector valve of the invention accomplishes these desirdata by providing a combination of design improvements over prior art electromagnetic fuel injector valves. Most notable among the design improvements are: a lighweight plunger, a flat-faced armature, dual adjustment of the valve seat and biasing on the plunger, and a wet coil construction whereby the electromagnetic coil is cooled by fluid flowing through the valve.
