ABSTRACT:
An accumulator having an internal valve opened by applying air pressure to a diaphragm with a small solenoid to apply air to the diaphragm where the air is supplied from a pilot air supply. When the internal valve operated by the diaphragm opens, it snaps to a fully open position thereby opening the valve and uncovering a passageway leading to a filter for cleaning. The passageway is sufficiently wide that the resulting flow of air through the passageway is so explosive that air pressure on the filter is distributed over the surface area of the filter for a brief moment, blowing the dust on the filter free.
