ABSTRACT:
An inlet valve for a two-tower air drier for directing an air flow from a central inlet to either tower through a respective one of a pair of opposed outlets. A valve body is axially movable between two valve seats and is provided with two annular flanges at such an axial distance from each other that at no position of the valve body will a flange cover any part of the central inlet. A restricted flow area past the flanges is accomplished as a flange moves towards its respective valve seat. The valve body is biased towards a neutral position by a helical compression spring, which is attached to the housing of the valve with its two ends and passes through an aperture in a stem of the valve body between the two flanges.
