DISPOSITIF DE CONTROLE DE LA REGENERATION DE L'ELEMENT FILTRANT D'UN EPURATEUR POUR UNE INSTALLATION PNEUMATIQUE DE FREINAGE POUR VEHICULES AUTOMOBILES

Control device regeneration filter element (13) a scrubber (11-20) for installation pneumatic brake comprising a compressor (c), at least one storage container (b) for storing the pressure, and a pressure regulator (21 to 36); understanding the scrubber an envelope (11) in which you define a cavity in which is housed the filter element (13) and having an inlet (1) for air from the compressor (c) and an outlet (2) waters filter element down (13) connected to go for at least one such deposit (b) and which is associated with a check valve (18-20) designed to prevent backflow of air from the tank (b) the pressure in the container (b) reaches a preset value and the pressure regulator (21-36), therefore, discharge to atmosphere air delivered by the compressor (c); characterized said device that it comprises: a body (10) with an inlet or admission (40) and an outlet (42) connected by a conduit (41, 42) and are to ir connected to the output ( 15) cleaner (11 to 15), respectively upstream and downstream of said check valve (18-20); an intercept valve (46, 47) disposed in said conduit (41, 42); and control means (44, 50 to 55) associated with said shutoff valve (46, 47) and designed to maintain the valve (46, 47) open during each of the phases in which the pressure regulator vent delivered by the compressor to allow through said conduit (41, 42) backflow regeneration air from said at least one tank (b) through filter element (13) cleaner, while the difference between the pressure maxima reached at least one such deposit (b) and pressure instantanea said tank (b) is below a preset value.
