Abstract
A device for conducting cooling liquid out of a liquid cooled rotor type rotary electric machine in which a sealing means is provided for preventing the leakage of cooling liquid from an outlet chamber adapted to receive the cooling liquid discharged from the rotary electric machine. The sealing means employs a thread seal and a rubber seal in combination. The rubber seal is provided in such a manner as to surround a cooling liquid supplying and draining pipe and so that it is expanded or contracted according to the pressure of gas introduced inside the rubber seal to adjust the gap between the rubber seal and the pipe. The pressure of gas is controlled according to the speed of rotation of the rotor shaft or the amount of liquid leakage.
