ABSTRACT:
An electric valve for pipe organs is adapted to be mounted within an air chest and is provided with a valve member on an armature adapted to cooperate with a valve seat surrounding an air passage in the chest leading to a pipe. The valve member is comprised of a base member, a resilient member and a valve seat engaging member adhesively secured together with sufficient slack in the valve seat engaging member or the base member and air passages which permit direct contact of the pressurized air within the air chest with the valve seal engaging member to allow bounce of the armature while maintaining the valve seat engaging member in engagement with the valve seat. The armature extends through and is pivoted on a bracket by means of two ball bearings press fitted into sockets on opposite sides of the armature. The sides of the bracket are then pressed toward each other against the ball bearings which will then be pressed into the bracket to form complimentary sockets.
