Abstract
A ventilation device for transmissions with lubricant comprising water, the device being disposed above the transmission () and being connected thereto by way of a line () and comprising a pressure equalization opening () that leads to the surrounding environment, is to operate without loss of evaporating water to the environment. To this end, the device comprises at least one container () designed as a condenser for evaporated water rising through the line (), the container being provided with a cooling element for dissipating heat (), the condensate passing from said container () back to the transmission (). In one variant, two containers containing a fluid are described which communicate with one another by way of a U-shaped channel.
