とを特徴とする分注装置用制御装置。 Two check valves arranged in a vertical flow path, and a piston-type valve device arranged between these check valves to control the amount of fluid flowing from the upstream check valve to the downstream check valve. In the dispensing device, the check valves are bent at right angles at two points between the two check valves to form a vertical flow path portion, a horizontal flow path portion, and a vertical flow path portion, and the valve device A valve portion made of an elastic material arranged coaxially with the flow path portion and provided at the tip of the piston portion has a diameter greater than or equal to the diameter of the horizontal flow path portion, and the valve portion is inserted into the horizontal flow path. 1. A control device for a dispensing device, characterized in that the horizontal flow path is occluded.
