Venting device for a gas-containing liquid medium

摘要

The working pressure range of a vent device comprising a gas-collecting chamber (4), a float (13) and a valve (7) which can be actuated via a linkage (20) can be considerably extended, without the risk of tilting or sticking of the float during automatic operation, if a ball (13) in a three-point guide (14) is provided as the float. <IMAGE>
