Abstract

PURPOSE:To prevent the vaporization of liquid compound injected to a closed system, by screwing and fixing an injecting nozzle to a cylinder, and at the same time by letting an injecting pipe attached at the top of the injection nozzle pass through a hole through which the nozzle penetrates. CONSTITUTION:A pair of kneading screws 1a, 1b are arranged in a cylinder 2 and are rotated in the same direction. The opening 4, pointed to the inside of the cylinder 2, of a nozzle hole 3, which is made in the upper part of the cylinder 2, is faced to one of a pair of said kneading screws arranged in the direction of rotation of the upper part of the screws, i.e. the kneading screw 1a, and is located at the position turned from the axial core of the screw 1a. An injecting nozzle 5 is fixed by screwing to the cylinder 2, and an injecting pipe 6 attached at the top end of the injecting nozzle 5 is made to pass through the nozzle hole 3 so that the top end of the injecting pipe 6 may be located at the opening 4 of the nozzle hole positioned in the cylinder 2.
