Abstract
The invention relates in particular to the inner breathing mechanisms (27) used in the spring brake actuators employed in the brake control systems of the automotive sector, said mechanism comprising the monobloc piston bearing (31) having the piston (1) and the piston pipe (26); the sealing member (4) that prevents the passage of the pressurized air from the rear service room (13) to the rear emergency braking room (15); the spring (3) that enables the sealing member (4) to be pushed; the spring bearing (2); the blind plug (6) that prevents the air contact of the mechanism (27) with the rear service room (13); the stopper (7) that enables the formation of the air circulation zone; the release hole (9) that provides the exchange of air; the air circulation zone (10).
