ABSTRACT:
A rotary magnetic valve including a cylindrical housing having flow passages in both ends and a magnetically-responsive valve closure assembly rotatively mounted therein. The valve closure assembly includes an armature mounted to rotate about the longitudinal axis of the housing and a shoe slideably disposed on each end of the armature. Each shoe is biased away from the armature and into contact with the inner end surfaces of the housing. A controller assembly is provided to rotate the valve closure assembly between a first position where flow through the valve is prevented and a second position where flow is permitted. The controller includes at least one permanent magnet for biasing the valve closure assembly into one of the positions and an electromagnet for rotating the valve closure assembly into the other position. A three-way valve is also possible.
