Abstract:
1. A valve device for a compressed air supply system, comprising: a control chamber chargeable with compressed air; a control piston plate delimiting the control chamber; a control piston attached to one side of the control piston plate that faces away from the control chamber; a blow-off valve chamber of a blow-off valve, the blow-off valve chamber being provided with at least one compressed air port and having the control piston project into the blow-off valve chamber; a valve plate delimiting the blow-off valve chamber and being activatable with force in a direction of a valve seat via a spring, the valve plate being liftable off of the valve seat by the control piston counter to the force of the spring in order to open the blow-off valve; a valve housing surrounding the control piston, the control piston and the valve housing defining at least two regeneration valve chambers of a regeneration valve, each of the regeneration valve chambers having at least one compressed air port and; wherein the at least two regeneration valve chambers are separable from one another by placing the control piston into a first position and connectable to one another via a passage by placing the control piston into a second position, the passage being formed in or on the control piston, and the at least two regeneration chambers are configured such that when connected, air passing from a first one of the at least two regeneration chambers through the passage to a second one of the at least two regeneration chambers passes out of the second one of the at least two regeneration chambers.
