Abstract:
An electrically controlled flow valve comprising:a valve body defining a cavity having an interior surface and including first and second ports extending exterior of said valve body, and a valve seat between said first and second ports;a magnet coil within said valve body;a valve core within said coil fixed to said valve body for channeling magnetic field through said coil;a spider positioned within said cavity, said spider carrying an armature positioned in opposition to said valve seat, said spider affixed at an outer edge thereof to said valve body, said spider comprising one or more deflectable spring arms extending between said outer edge and said armature, said spider further comprising one or more spring beams extending from said spider and engaging a contact point of interior surface of said cavity, said spring arms and spring beams permitting axial movement of said armature assembly within said cavity for movement toward and away from said valve seat for blocking and unblocking said first port;wherein current through said coil generates magnetic force to move said armature relative to said first port and valve core.
