Abstract

PURPOSE:To enhance the erosion resistance of the inner wall of an outlet chamber and to prevent noise and cavitation by providing a containing member so as to surround the opening of a cooling liquid flowing path in the outlet chamber, holding the containing member in the filled up state by the cooling liquid, and exhausting the liquid into the outlet chamber through an introducing path. CONSTITUTION:In an outlet chamber 612 which exhausts cooling liquid discharged from a flowing path 3b of an inlet and outlet pipe 4 to the stator side, a discharge ring 10 with small holes 10a is installed at the opening end of the flowing path 3b, and a ring-shaped containing member 11 is provided so as to surround the small holes 10a. The discharged cooling liquid is filled up in the containing member 11. The containing member is connected to the outlet chamber 612 through gaps G formed between the end portions 11a and 11b and the inlet and outlet pipe 4, and an introducing paths 12 which introduce the cooling liquid in the filled up state. In this constitution, since the cooling liquid does not strike the inner wall of the outlet chamber 612, erosion of the inner wall and generation of noise can be prevented.
