Abstract:
In a soft start device for pneumatic systems comprising a primary inlet where compressed air can be supplied at primary pressure, wherein the primary inlet is, via a valve circuit, connected to at least one secondary outlet which can be coupled to a load and where compressed air can be discharged at secondary pressure, the secondary pressure being lower than or equal to the primary pressure, wherein a main valve is installed between the primary inlet and the secondary outlet, a restrictor device being installed in the bypass, wherein the main valve and the restrictor device together with further directional valves of the valve circuit are interconnected such and the valve circuit can be switched into a standard switching position for venting such that the secondary outlet is vented, the valves of the valve circuit are interconnected such that several further switching positions for venting are possible.
