Title: DEVICE FOR PROTECTING COMPONENTS AGAINST LIQUIDS AND FOR VENTILATING THE SAME
Abstract:
The invention relates to a device for protecting components, housings and the like against liquids and for ventilating the same, the device comprising at least one first layer, wherein the first layer is designed in the form of a membrane and the latter has a first region, such that the first region is gas-permeable and liquid-tight below a first liquid pressure, and also comprising at least one second layer, wherein the second layer is connected in a pressure-tight manner at least to some extent to the first layer and has a second region, which is designed such that, at a liquid pressure greater than or equal to the first liquid pressure, the first region and the second region interact for liquid-sealing purposes.
