Claims

[Scope of utility model registration request]

“The measuring cylinder and the opening/closing cylinder are connected in a straight line, the piston rod of the opening/closing cylinder is protruded into the measuring cylinder, and the piston rod of the measuring cylinder is pushed by the valve body placed inside the measuring cylinder. The first plate is formed so as to communicate with both the front and rear sides.
closes the flow path and opens a second flow path communicating from inside the metering cylinder to its discharge port, and the piston of the metering cylinder moves forward together with the valve body until the second flow path is closed by the valve body. a metering valve configured to discharge the liquid in the metering cylinder from the discharge port in between, and forming a third flow path in the piston rod that opens into the surface that slides into contact with the housing and into the metering cylinder. In addition, i number of grooves sequentially communicating with the third flow path are formed in the inner circumferential surface of the housing that is in sliding contact with the piston rod, and each groove is arranged in a corresponding manner to each other. 1. A metering valve having a plurality of discharge ports, the metering valve being in communication with a discharge port formed by the method.
