Abstract
A valve solenoid includes a coil pot having an internal volume. A coil is positioned concentrically within the internal volume. An outer tube is positioned concentrically within the coil. A pole core is positioned concentrically within the outer tube. An armature includes an armature first portion positioned distal from the pole core and an armature second portion at least a portion of which is positioned concentrically within the outer tube. An inner tube is positioned concentrically within the channel defined by the armature such that the at least a portion of the armature second portion is positioned concentrically between the outer tube and the inner tube. An armature pin is fixedly coupled to the armature. A biasing member is positioned within the channel. A first end of the biasing member is coupled to the armature pin and a second end of the biasing member coupled to the pole core.
