摘要 |
A cylinder 2 is formed with an upper guide bore 10a and a lower guide bore lOb at a position corresponding to a gate part B. Gate rods 7 are rotatably inserted through the guide bores 10a, lOb respectively. Each of the gate rods 7 is formed with opening degree changing recesses in a form of an opencut adjacent to each other in an axial direction in order to constitute opening degree variable channels S in combination with opening degree variable channel forming parts 14 of two screws 3. Each of the recesses 11 consists of a first semicircular face 12 and a second semicircular face 13 in such a shape that an upstream side end of the first semicircular face 12 is diagonally cut. By rotating the gate rods 7 in a positive and a reverse directions, the opening degree can be changed between a fully opened state wherein the first semicircular face 12 and the opening degree variable channel forming part 14 are in parallel and a fully closed position wherein the second semicircular face 13 is in abutment against the opening degree variable channel forming part 14. <IMAGE> |
