Abstract. A pilot valve is described for control of a pulse valve for e.g. production of pulses of compressed air. The pilot valve comprises a housing having an inlet and an outlet, a movable valve element disposed inside the housing, and means for switching said valve element between a closed and an open position, said inlet and outlet communicating in the open position. At least a portion of the interior of the housing presents in one plane a circular shape, the outlet being formed as a radial slot from this portion around at least a part of the periphery. The valve element is designed as a flexible disc which in the closed position is located in said plane to seal the slot with its outer edge at the inner side of the housing. Said means are arranged to switch the valve element to the open position by giving the disc a curved shape so that the outer edge no longer covers the slot.
