Suspension system for a driver's compartment on a vehicle chassis, comprising: - a mounting arrangement for mounting the driver's compartment on the vehicle chassis including at least two pneumatic springs to be arranged along a lateral side of driver's compartment and coupled between the driver's compartment and the vehicle chassis; - a pressure supply and an atmospheric vent; - for each pneumatic spring respectively, a valve device communicatively coupled to the pressure supply; the vent and a respective pneumatic spring via a respective pressure terminal; vent terminal and spring terminal; - a vehicle state control system that provides a pressure set value in the pneumatic spring; - a pressure controller arranged to the valve device alternatively for pressurizing or depressurizing the pneumatic springs; - wherein the valve device comprises at least a first valve (15, 16) having a valve outlet coupled to the spring terminal and a valve inlet communicatively coupled to the pressure terminal, and characterized in that the first valve comprises ∘ a valve seat having an effective orifice (A orifice) and separating the valve inlet and the valve outlet; ∘ a valve member that is pressed in normally closed condition against the valve seat by a spring means; so that in use, an inlet pressure is exerted on the valve member via the valve seat orifice, the valve member being enclosed in the valve outlet so that an outlet pressure counteracts on the valve member; the valve member being subject to force generated by a pressure difference between inlet and outlet; and ∘ an electric actuator (156, 160) mechanically coupled to the valve member having a continuously variable force set point so as define, by the pressure controller, a set force counteracting the pressure difference, to generate a set pressure in the pneumatic spring derived from the vehicle state control system irrespective of gas mass flow and gas temperature. - a mounting arrangement for mounting the driver's compartment on the vehicle chassis including at least two pneumatic springs to be arranged along a lateral side of driver's compartment and coupled between the driver's compartment and the vehicle chassis; - a pressure supply and an atmospheric vent; - for each pneumatic spring respectively, a valve device communicatively coupled to the pressure supply; the vent and a respective pneumatic spring via a respective pressure terminal; vent terminal and spring terminal; - a vehicle state control system that provides a pressure set value in the pneumatic spring; - a pressure controller arranged to the valve device alternatively for pressurizing or depressurizing the pneumatic springs; - wherein the valve device comprises at least a first valve (15, 16) having a valve outlet coupled to the spring terminal and a valve inlet communicatively coupled to the pressure terminal, and characterized in that the first valve comprises ∘ a valve seat having an effective orifice (A orifice) and separating the valve inlet and the valve outlet; ∘ a valve member that is pressed in normally closed condition against the valve seat by a spring means; so that in use, an inlet pressure is exerted on the valve member via the valve seat orifice, the valve member being enclosed in the valve outlet so that an outlet pressure counteracts on the valve member; the valve member being subject to force generated by a pressure difference between inlet and outlet; and ∘ an electric actuator (156, 160) mechanically coupled to the valve member having a continuously variable force set point so as define, by the pressure controller, a set force counteracting the pressure difference, to generate a set pressure in the pneumatic spring derived from the vehicle state control system irrespective of gas mass flow and gas temperature. ∘ a valve seat having an effective orifice (A orifice) and separating the valve inlet and the valve outlet; ∘ a valve member that is pressed in normally closed condition against the valve seat by a spring means; so that in use, an inlet pressure is exerted on the valve member via the valve seat orifice, the valve member being enclosed in the valve outlet so that an outlet pressure counteracts on the valve member; the valve member being subject to force generated by a pressure difference between inlet and outlet; and ∘ an electric actuator (156, 160) mechanically coupled to the valve member having a continuously variable force set point so as define, by the pressure controller, a set force counteracting the pressure difference, to generate a set pressure in the pneumatic spring derived from the vehicle state control system irrespective of gas mass flow and gas temperature.
