发明名称 Device for sealing pressure compensation openings
摘要 The invention relates to a device for sealing pressure compensation openings in components in particular of a motor vehicle control unit. Previously, pressure compensation openings were sealed in the interior of the housing by a watertight and gas-permeable material affixed by adhesion. In accordance with the invention, the opening is sealed from the outside with a two-layered material where a wide-area first layer consists of a material that can be inscribed and a second layer, which can also be provided over just a part of the total area, is a watertight and gas-permeable membrane. At those places where pressure compensation occurs, the first layer is removed so that only the membrane acts. The first layer can be used here as a label. Advantages offered by this device are that the housing and the membrane are joined over a much larger area, the process can be monitored, and one process step is saved.
