1284.40 TH/BLAB 1979-02-14 Abstract of disclosure The present invention relates to an air controlling device adapted for driers for compressed air and provided to change the communication between an inlet and an exhaust on one hand and a first outlet and a second outlet on the other hand, the device being provided in a first functioning condition to connect the inlet with the first outlet and the second outlet with the exhaust and in a second functioning condition to connect the inlet with the second outlet and the first outlet with the exhaust while being actuated by power impulses. According to the invention the device is provided with a first and a second duct, to each one of which one of the outlets is connected, a first valve arranged in an alternating manner to connect the inlet to one of the ducts, a second valve, which is arranged to connect the exhaust to that duct, which at that moment is not connected to the inlet, an actuated organ, which is moveable by means of a power means between a first position, in which it retains the second valve in the connecting position it has taken and permits communication from the valve to the exhaust, and a second position in which the valve is free to change its connection position, and in which the communiation between the valve and the exhaust pipe is interrupted, the first valve and the second valve being providedto change position during the period, when the said organ occupies its second position and in that way that when the first valve in its connecting condition maintains the first one of the ducts in communication with the inlet the other valve maintains the other duct connected to the exhaust and vice versa.
