<p>The safety valve is designed for venting of the tan of the motor-car when refuelling. The valve (1) is supplied with a pipe-end (5) opened into the environment, which closes under normal pressure by a closer (6), which is actuated by a membrane (8). If pressure in the safety valve (1) increases, membrane (8) causes the opening of the closure (6) in the pipe-end (5) into the environment.</p> |
