| 摘要 |
The pressurized air device has an Electropneumatic pressure regulator (2) with an integrated mechanical-pneumatic pressure regulator (3) with the same or a lower cutoff pressure, an integrated Electropneumatic multi-circuit protection valve (45) and an air dryer (9), contained in a common housing (1) with a controlled safety outlet valve (14). The mechanical-pneumatic pressure regulator is blocked when the operating voltage is intact and provides back-up function for the Electropneumatic pressure regulator for operation of the control devices (4,5,6) for the individual pneumatic circuits.
