VENTILATION DEVICE FOR THE DISCHARGE PIPE OF A WATER SUPPLY HOUSEHOLD APPLIANCE |
摘要 |
<p>A ventilation device for the discharge pipe for removing a flow medium pumped to a household appliance. A pipe ventilation valve is connected to the discharge pipe by a channel and comprises a valve body disposed in a float chamber filled with a working medium which is separated from the flow medium and actuates the valve body. The valve body is actuated by transmitting a pneumatic force between the flowing medium and the working medium of the float chamber or between the flowing medium and a sealing surface adjacent to the valve body by means of a pressure medium which is separated from the flowing medium and is enclosed in the channel. The inventive pipe ventilation device makes it possible to avoid a direct contact between the valve body of the pipe ventilation valve and the flowing medium, thereby preventing the valve body from being soiled.</p> |
