PURPOSE:To enhance the erosion resistance of the inner wall of an outlet chamber and to prevent the generation of noise by providing a shielding body to prevent the direct strike of the cooling liquid at the location opposing the open end of the cooling liquid flowing pipe in the outlet chamber. CONSTITUTION:In an outlet chamber 612 for exhausting the cooling liquid discharged from a flowing path 3b of an inlet and outlet pipe to the stator side, a discharge ring 10 having small holes 10a is installed at the open end of the flowing path 3b. A ring-shaped body 11 is attached to the inner wall of the outlet chamber with bolts and the like so as to cover the small holes 10a. In tis constitution, since the cooling liquid discharged from the small holes 10a strikes against a surface 10a of said shielding body 11 and runs away, and the liquid does not directly strike the inner wall of the outlet chamber, the erosion of the inner wall can be prevented, and since the strike sound is decreased by attaching bolts and the like, and noise can be decreased. |
