01/01/1970 Link:
The invention relates to an operating unit for nautical use, wherein an internal combustion engine drives an electric energy generator. According to the invention, the generator is cooled by oil in which the rotor and the stator are partly immersed: the spinning motion of the rotor drags the oil into the air gap, thus cooling the stator as well.
