Abstract
The nozzle is constituted by a nozzle body and a connecting block. The nozzle body is constituted by a casing and a core. A first passage is formed in the center of the core and a second passage is formed between the external surface of the core and the internal surface of the casing. The first passage and the second passage join together in front of the core and then lead to a discharge port at the tip end of the casing. In the interior of the connecting block are formed a first supply line and a second supply line. The first supply line connects a sub injection unit to a first supply port, and a first stop valve is provided within the line. The second supply line connects a main injection unit to a second supply port, and a second stop valve is provided within the line.
