Abstract
An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a cylindrically-shaped coil of wire. The valve member moves between a seated position and an unseated position in response to energizing the electromagnet. A flux sleeve passes through the coil and includes two magnetic portions interconnected by a non-magnetic portion. Each of the magnetic portions is aligned with transverse planes defined by the ends of the cylindrical coil. The non-magnetic portion is axially positioned between the transverse planes.
