Abstract
A solenoid for uses such as in a valve for fluid flow control. The solenoid has an armature movable within a core in response to current in a field coil. The armature is shaped as a cone with a hemispherical end so as to give a power output that is a substantially linear function of said current. In a valve, valve control means connects a valve member to the armature for moving the valve member to and from a valve seat to control fluid flow therethrough.
