Abstract
The present invention relates to a ventilating and evacuating valve for fluid-guiding conduit pipes or braces. The valve includes a valve mechanism and a floating body which acts on the valve mechanism. The valve mechanism includes a valve body which can be moved into different opening or closing positions in order to open and close a valve outlet; a diaphragm cup; and a roll diaphragm which is arranged between the valve body and the diaphragm cup and can come to rest in different opening or closing positions over aperture openings of the valve body. The valve also includes a channelling mechanism which is configured to guide an evacuating flow past the valve mechanism.
