A self-cleaning airflow regulator (100) includes a partially air pervious poppet cylinder (134) disposed between a pair of spaced-apart sidewalls (130, 132) of a restriction chamber (128) to move along the sidewalls in a direction transversely to the length of the poppet cylinder toward and away from an air inlet (136) for directing supply air into the restriction chamber. The restriction chamber includes an air outlet (138) located on the opposite side of the poppet cylinder from a location of the inlet (136). Air entering the restriction chamber (128) through the inlet (136) pushes against the poppet cylinder to force the poppet cylinder to move toward the outlet (138) at the same time causing the poppet cylinder to rotate about its longitudinal axis due to the reactive contact of the poppet cylinder with diagonally disposed fibers (170) mounted on the inside surfaces of the walls (130, 132) of the restriction chamber. The rotation of the poppet cylinder (134) about its longitudinal axis place a new section of the poppet cylinder in alignment with the outlet (138) so that dust and other particlate matter collected on the outer surface of the poppet cylinder is removed therefrom by the air which leaves the poppet cylinder through the outlet (138). Air entering the restriction chamber is reduced in flow rate and pressure first during passage into the regulator inlet, then during passage into the poppet cylinder and then again during passage out from the poppet cylinder for exit from the restriction chamber through outlet (138).

A self-cleaning airflow regulator, comprising: (a) a housing including: a first chamber having a pair of spaced-apart sidewalls; an air inlet in airflow communication with the first chamber; and an air outlet in airflow communication with the first chamber at a location spaced from the air inlet; (b) a close fitting, partially pervious poppet cylinder within the first chamber at a location between the sidewalls thereof to occupy substantially the entire width separating the sidewalls, the poppet cylinder adapted to move transversely of its length along the sidewalls toward and away from the air inlet in response to the level of airflow through the first chamber; (c) means for biasing the poppet cylinder in the direction towards the air inlet to shift the poppet cylinder towards the air inlet when no air is flowing into the first chamber through the air inlet; and, (d) reactive contact means associated with the sidewalls of the housing which engage the poppet cylinder to cause the poppet cylinder to rotate about its longitudinal axis as the poppet cylinder moves along the housing sidewalls toward and away from the air inlet.
