Multi-circuit protection valve for compressed air production installations in vehicles

The valve has at least two overflow valves associated with each circuit, each with a valve element (4) in contact with a spring (5) and forming a gate valve with a valve seat to an air load associated with one of the circuits. Each valve is controlled by a control unit associated with its circuit an...

Beschreibung
Zusammenfassung:	The valve has at least two overflow valves associated with each circuit, each with a valve element (4) in contact with a spring (5) and forming a gate valve with a valve seat to an air load associated with one of the circuits. Each valve is controlled by a control unit associated with its circuit and has an actuation unit. Each valve element is a differential piston (10) with a piston seal (12) that reduces the effective surface (14) on the side remote from the spring and the force of the spring is dimensioned according to the desired opening pressure of the overflow valve on the reduced effective surface.
