Abstract
An armature for a solenoid actuator is disclosed. The armature comprises a first face comprising a recess suitable for receiving a biasing spring in use of the armature; a second face opposite the first face; and fluid communication passages for providing a fluid flow path through the armature between the recess and the second face in use of the armature. The first face is uninterrupted by the fluid communication passages. The invention reduces the risk of cavitation damage during operation of the actuator. In one application, the actuator is used in a fluid pump for a selective catalytic reduction system.
