Abstract

Una disposición de bomba de freno de relación variable que tiene un alojamiento que define un depósito de fluido, un ánima escalonada definida por dicho alojamiento y que incluye una parte de diámetro grande y una parte de diámetro pequeño, teniendo dicha parte de diámetro grande una pared extrema, caracterizada por un primer pistón operable dentro de la parte de diámetro pequeño del ánima y de la parte de diámetro grande del ánima, un primer cierre asociado con dicho primer pistón y destinado en una posición a dividir dicha ánima de diámetro grande en una primera cámara definida hacia atrás de dicho primer cierre y en una segunda cámara definida entre dicho primer cierre y dicha pared extrema, una válvula dosificadora de superficie diferencial dispuesta entre dichas cámaras primera y segunda y destinada a dosificar el fluido que va de dicha segunda cámara a dicha primera cámara cuando existe una diferencia de presión predeterminada entre dichas cámaras primera y segunda, teniendo dicha válvula dosificadora una superficie de apertura de la válvula expuesta a la presión que reina en dicha segunda cámara, una superficie de cierre de la válvula menor que dicha superficie de apertura de la válvula, expuesta a la presión que reina en dicha primera cámara, y medios de carga que empujan dicha válvula hacia una posición cerrada, y una primera salida de fluido en comunicación con dicha segunda cámara.
