Beschreibung
Zusammenfassung:	The present invention relates to a hydraulically actuatable pneumatic valve mechanism comprising at least one hydraulic connection (P41, P42) and at least one compressed-air connection (P43), at least one compressed-air outlet (P22), and at least one transmission lever (6) that can be actuated by means of the hydraulic connection (P41, P42) in such a way that the outflowing compressed air from the compressed-air outlet (P22) can be adjusted, an actuating piston (4) being provided which can be hydraulically actuated by means of the hydraulic connection (P41, P42) and which actuating piston (4) is guided in a movable housing part (1). In the region of the compressed-air outlet (P22) a pneumatically actuatable blocking element (7) is provided by means of which the movement of the transmission lever (6) can be limited.
