ABSTRACT:
The compressed air flow in an air drier is directed to either one of its two drying towers by a switch-over valve whose switch-over function is performed with the air drier unloaded by an unloader valve arranged between the air drier and a compressor. The unloader valve is caused to perform its unloading function not only at a predetermined pressure in an air tank to which the air is fed but also--by an electronic control device--after a predetermined time during periods of prolonged continuous air loading from the compressor through the air drier even if the predetermined pressure is not reached.
