PURPOSE: To have easy control of fluid flowing in a plurality of passages by furnishing an external communication hole and a communication hole within a valve body, and by installing an ejector in said communication hole.
CONSTITUTION: A passage is formed when a valve is opened to allow fluid to move through it. On the other hand, a communication hole 3 provided in the center of valve body 2 is situated in right angle to the passage when the valve is opened. In the condition in which the tip of nozzle 5 is oriented toward right, the fluid 8 passes through said communication hole 3 to move to the right from the left of valve body 2. Due to this movement of fluid 8 a suction force acts from the external communication hole 4 side to the communication part at the tip of nozzle 5 by means of ejector action, and the solution is supplied into the communication hole 3 from a vessel 7 via a joint pipe 6 and the external communication hole 4, and pharmaceuticals in specified amount is mixed with the fluid 8.
