ABSTRACT:
An arrangement for liquid supply into the rotor of an electric machine comprises a bush mountable on the rotor shaft and having a duct for passing the liquid therethrough and projecting circular partitions, and a pressure, drain, and a collecting circular chambers embracing the bush. These chambers are formed by interconnected stationary circular partitions mounted with a clearance relative to the bush circular partitions. Each of the clearances of the pressure and of the collecting circular chambers is sealed by a sealing plate made of resilient rubberlike material, mounted in these chambers and fixed on the stationary circular partition or on the bush partition, and contacting with its operating surface with another one of these partitions.
