Abstract

A flushing air valve for selectively subjecting a selected filter member or members to a flushing air impact to remove a dust deposit on the member. The valve member of the type of an axially movable plate closes a conduit between a flushing air chamber and a clean air plenum adjacent the respective filter disposed in a cleaning compartment of a dust removing filter apparatus. The opening and closing of the valve is governed by opening or closing of a pilot exhaust valve. As the pilot valve opens, the flushing air pressure acting on the side of the valve member facing the exhaust is reduced so that the flushing air pressure acting on the opposite face of the valve member opens the valve. Means providing an air cushion for decelerating the opening stroke of the valve member is provided to prevent the valve member from striking against the chamber wall, to thus reduce the noise of operation of the valve. The required pressure of the flushing air is reduced as the operation is governed solely by opening or closing the pilot valve, without any further requirements for the operation of the pilot valve, such as re-directing the flow of the flushing air etc.
