Claims

[Scope of Claim for Utility Model Registration] (1) A tubular valve body whose interior serves as a flow path, a ring-shaped disc portion that partially blocks the flow path within the valve body, and an erected portion on the inner periphery of the valve body. A fixed disk cap consisting of a cylindrical cap having an opening in the cylindrical portion, a ring-shaped disk portion rotatably provided opposite to the concave side of the fixed disk cap, and a standing portion on the inner periphery of the fixed disk cap. a rotary disc cap comprising a cylindrical cap having an opening in the cylindrical part, and the cylindrical part fitting eccentrically into the cylindrical part of the fixed disc cap; A control valve comprising a substantially cylindrical rotary drive motor that rotates around the center of a plate cap. (2) A tubular valve body with a flow path inside, a ring-shaped disc part that partially blocks the flow path of the valve body, and an opening in the cylindrical part that stands upright on the inner circumference of the valve body. A fixed disk cap consisting of a cylindrical cap with a protrusion formed on the inner peripheral surface around the opening, and a ring-shaped disk portion rotatably provided in opposition to the concave side of the fixed disk cap. and a cylindrical cap that is erected on the inner periphery of the cap and has an opening in the cylindrical portion, the cylindrical portion of which contacts the projection on the inner periphery of the cylindrical portion of the fixed disk cap, and fixed to the valve body. and a substantially cylindrical rotary drive motor that rotates the rotary disk cap around the center of the fixed disk cap. (3) The rotary drive motor includes a ring-shaped vibrating body that is in contact with the disk portion of the rotary disk cap, and a ring-shaped vibrating body that is fixed to the side opposite to the disk portion of the vibrating body and that excites the vibrating body. 3. The control valve according to claim 1, wherein the control valve is an ultrasonic motor stator having a piezoelectric element and rotating the rotary disc cap.
