Abstract (en)
[origin: WO2009100734A1] The invention relates to a soft start device for compressed air systems having a primary inlet (P1) that can have compressed air fed thereto under primary pressure, wherein the primary inlet (P1) is connected to a secondary outlet (P2) that can be coupled to at least one consumer by means of a valve circuit that can have compressed air discharged therefrom under secondary pressure, wherein the secondary pressure is less than or equal to the primary pressure, wherein a main valve of type 2/2 (normally closed ) that can be bypassed by means of a bypass (17) is connected between the primary inlet (P1) and the secondary outlet (P2), wherein a throttle device (13) is connected in the bypass (17), wherein the main valve (WV5) and throttle device (13) and further valves (WV1, WV3, WV4, WV5, WV6) of the valve circuit are connected to each other, and the valve circuit can be set to a standard venting setting, such that the secondary outlet (P2) is vented, wherein the valves (WV1, WV3, WV4, WV5, WV6) of the valve circuit are connected to each other such that, in addition to the standard venting setting, a plurality of further venting settings are possible, wherein each of the further venting settings result when any arbitrary one of the existing valves (WV1, WV3, WV4, WV5, WV6) has a fault during the actuation process normally bringing about the standard venting setting.
