Abstract

Un sistema accionador de freno de un veh?culo que comprende un dise?o de diafragma con un agujero y elemento sellador en el centro. El dise?o permite al elemento sellador sellar y deslizarse sobre el di?metro exterior de la varilla de empuje central por la longitud expuesta. Esto elimina la necesidad de una junta fija para unir en forma permanente el diafragma a la varilla de empuje central, y permite a la varilla de empuje unirse al pist?n de resorte o a una placa fija separada y reduce la tensi?n del diafragma en su interconexi?n.
