Abstract
A solenoid valve for fluid flow control, in which 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. 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.
