Ventilation cover for ventilation bore, has ventilation gap that is continued to be opened to stagnation pressure area turned away from side of cap and extended at side, where cap and/or lid have outer contours with edges diverting medium

摘要

The cover has a cap (2) that is arranged and/or formed such that the cap executes a tilting motion around a projection (4) during an occurrence of an impact pressure formed by a sputtering washing medium. A side of the cap lying in the pressure area seals a closing lid (1), and a side of the cap turned to the area is further opened. A ventilation gap (8) is continued to be opened to stagnation pressure area turned away from the side of the cap and the gap is extended at the side. The cap and/or the lid have outer contours with separation edges diverting the washing medium.
