A valve combination combines in it a shut-off valve (10) and a blow-off valve (12). The two valves have closing bodies (22, 40) which interact respectively with a valve seat (20) and a outlet nozzle (42). The closing bodies are drive-connected to one another via a tappet (26, 28, 32, 34, 36), in such a way that, with the shut-off valve (10) closed, the blow-off valve (12) is opened and, with the shut-off valve opened, the blow-off valve is closed. Notches (34) in the tappet (32) make a connection between the space behind the valve seat (20) of the shut-off valve (10) and the space in front of the outlet nozzle (42) of the blow-off valve (12). <IMAGE> |
