摘要

The venting device (1) includes a housing (2) with a chamber connected to a heating system by an aperture (6) at the bottom. The chamber contains a vertically movable float (10), dividing it into lower and upper chamber cavities (4, 5). There is a valve lever (12) in the upper chamber cavities, movably connected to the float, to open and close the venting aperture (23). There is a connecting channel (14), linking the lower chamber cavity to an annular gap (15).
