Abstract
A fluid control valve includes a valve member in the form of a sleeve which is shaped to co-operate with a seating defined about a bore in a valve body. The sleeve has a rod extending therein, the rod being coupled to an armature of an electromagnetic device including a stator having a winding. A resilient bush is located between the rod and the sleeve to allow limited further movement of the armature after the sleeve has engaged the seating.
