Electrical/electronic device e.g. electronic pump head, case for e.g. internal combustion engine, has membrane with cover fixed to external face of closing plate to extend upper end of channel to block channel in water-tight manner

摘要

The case has a respirator (12) with a channel (14), which crosses a closing plate (52) to link an inner volume with an outer volume of the case. A membrane (22) has a cover that is fixed to an external face of the closing plate to extend an upper end of the channel to block the channel in a water-tight manner to let in gas. The cover has a plate that extends horizontally to the closing plate.
