Abstract
A venting device for a motor vehicle drive component is provided with an air feed device which has an air guiding region, by way of which the air feed device can be connected in a fluid-conducting manner to an interior chamber to be vented, and with a membrane vent which has a venting membrane which is permeable to water vapor in a first flow direction and which is impermeable to water vapor in a second flow direction. The membrane vent is connected at least temporarily in a fluid-conducting manner to the air guiding region, wherein an inlet air direction is directed through an imaginary flow direction out of the surroundings which surround the venting device, through the venting membrane and to the air guiding region, and wherein the venting membrane is arranged in an air guide housing such that it is impermeable to water vapor in the inlet air direction. An inlet air shut-off valve is arranged downstream of the venting membrane and upstream of the air guiding region in the inlet air direction. A fluid flow from the air guiding region to the venting membrane, that is to say counter to the inlet air direction, can be prevented by way of the inlet air shut-off valve.
