Abstract: PURPOSE:To finely regulate a nozzle opening/closing temperature without varying the area of a nozzle opening and to always easily regulate predetermined cooling characteristic by providing gas pressure regulating means for regulating the pressure at a gas sealed section. CONSTITUTION:The opposite side end of a clamping jig 10, fixed to a chassis 7 and containing a gas sealed section 4, to an actuator rod 6 is opened and a screw 5 is engaged with the end to block the end, and the one end of the gas sealed section 4 is engaged by the screw 5. Gas discharge amount from an orifice 2 is regulated by increasing or decreasing the initial opening area of the orifice 2 by a needle 3. The screw 5 is turned to regulate the pressure in the gas sealed section 4 to finely regulate the nozzle opening/closing temperature. That is, when the screw 5 is loosened, the volume of the gas sealed section 4 is increased, and the internal pressure of the sealed gas is reduced. When the screw 5 is clamped, the volume of the gas sealed section 4 is reduced, and the internal pressure of the gas is increased. The operating temperature of the gas sealed section 4 is varied in response to decrease or increase in the presence of the gas sealed section 4. Since the pressure in the gas sealed section 4 is regulated to regulate the nozzle opening/closing temperature, optimum cooling characteristic can be always obtained.
