Abstract:

An electromagnetically operated valve assembly having a valve closure means attached to a vertically suspended armature supported at its top portion, is held in magnetic fields at both the top and bottom portions of the armature, caused by permanent magnets reacting to iron or other permanent magnets. The movement of the armature is guided to insure close alignment and to eliminate side play by means of a main frame assembly mounted in a pipe organ wind chest so as to control air under pressure from the wind chest into at least one pipe organ. The permanent magnet at the bottom portion of the armature cooperates with an iron core of a solenoid mounted to the main frame assembly, to close or open the valve. The valve may also be provided with a second solenoid to both assist moving the valve to the open position, and to aid in holding the valve in the open position.
