Abstract

PURPOSE:To prevent erosion of the inner wall of an outlet chamber by providing a hard liner on the inner wall of the casing of the output chamber, to which cooling liquid is exhausted from a liquid-flow pipe in a rotary shaft in a cooling liquid discharging device and which prevents the outlet chamber from being filled up. CONSTITUTION:A discharge ring 10 with small holes 10a is attached to the opening of a flow pipe 3b provided in a rotary shaft, thereby an outlet chamber 612 is not filled up. A hard liner 11 comprising stainless steel and the like is provided on the inner wall of the casing of said outlet chamber 612. The area of the liner corresponds to the portion at least where the discharged cooling liquid contacts In this constitution, since the cooling liquid discharged from the discharge ring 10 is received by the liner 11, erosion of the inner wall of the outlet chamber 612 can be prevented by periodically replacing the liner 11.
