Abstract
A cooling liquid conducting out device having an outlet chamber which is partially filled with cooling liquid drained from the rotor of a rotary electric machine constructed such that the strength of collision of the cooling liquid with the inner walls of the outlet chamber is made small to prevent cavitation in the discharging section of a cooling liquid supplying and draining pipe. According to another aspect of the invention, the device is provided with a cooling liquid containing member which is disposed surrounding the discharging section of the supplying and draining pipe, which is maintained filled with the cooling liquid discharged through the discharging section, and which has discharging paths communicating with the outlet chamber. In addition to the discharging paths, conducting out passages for conducting the cooling liquid out of the containing member are provided to cause the cooling liquid thus passing through the conducting out paths to collide with the cooling liquid discharged through the discharging paths. Limiting members suchs are thread seals are provided in the discharging paths to reduce the amount of cooling liquid passing through the discharging paths.
