Abstract: An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. A flux sleeve is surrounded by a coil of an electromagnet. A pole piece defines a return passageway for reagent to flow. A filter surrounds the pole piece and includes a cage and a mesh fixed to the cage. The cage includes a deformable first seal biasedly engaging an outer surface of the pole piece. The cage includes a second seal biasedly engaging the housing. The first and second seals define a closed volume such that all of the reagent flowing through the injector passes through the mesh.

Abstract: A fluid pump includes a gear housing with a pocket wall and a base. The pocket wall and the base define a pocket that projects into the gear housing from a pocket surface. The fluid pump also includes a first gear rotatably positioned in the pocket. The first gear is spaced from the pocket surface by a first gap. The fluid pump also includes a second gear rotatably positioned in the pocket that engages the first gear. The second gear is spaced from the pocket surface by a second gap. The fluid pump also includes a selected shim that is selected from a plurality of shims in a shim set. The selected shim has a thickness that results in a desired clearance between the selected shim and the first face or the second face.
