Document Type and Number:
Japanese Patent JP3261105
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pipe unit reducing a space for the pipe, reducing the labor for piping works, and facilitating the maintenance.
SOLUTION: In a water-cooled box selectively providing paired three cooling nozzles and the same number of cooling water feed receiver ports by a shift operation, a pipe unit 10 for feeding cooling water to the feed receiver ports is constituted of an inner cylinder 11 fixedly arranged and connected to a cooling water supply source and an outer cylinder sliding around the outer circumference of the inner cylinder 11 in a bearing direction in a liquid tight state, a through hole 14 letting the fluid body pass from the inside to the outside is provided in one place in the inner cylinder 11, the outer cylinder 21 is so connected as to axially sliding with the shift operation of the water-cooled box, the inside of the outer cylinder 21 is liquid-tightly divided into partition chambers of the same number as the feed receiver ports axially, and the respective partition chambers 10A, 10B, 10C are connected to the feed receiver ports via a pipe.
