(EN) Motor Vehicle Device Lubricated With a Water-Containing Lubricant
Abrégé
(EN)

A motor vehicle device has a device interior in which a water-containing lubricant is held in order to lubricate at least one component arranged in the device interior. The device interior is fluidically connected to a venting apparatus for pressure equalization with the environment surrounding the motor vehicle device. The venting apparatus has a semipermeable membrane, which is water-impermeable in a first direction, i.e. from a first surface of the membrane to a second surface. The first surface of the semipermeable membrane faces the device interior and therefore the semipermeable membrane seals off the device interior from the environment surrounding the motor vehicle device in such a way that water and water vapor cannot permeate.
