Abstract

Perfeccionamientos en conjuntos de válvula de regulación para sistemas de frenos de vehículos, del tipo que comprenden una válvula de regulación que tiene un elemento de accionamiento de la válvula de regulación el cual funciona para controlar la comunicación entre un orificio de entrada y un orificio de salida, y un dispositivo de carga para aplicar una carga al elemento al elemento de accionamiento de la válvula cuyo dispositivo de carga comprende un dispositivo de palanca pivotada que coopera con el elemento de accionamiento de la válvula, y medios para variar la relación de palanca del dispositivo de palanca dependiendo de la carga del vehículo, caracterizados porque se dota de un dispositivo resiliente, preferiblemente un muelle, que aplica la fuerza de entrada al dispositivo de palanca, y porque la fuerza de entrada es prácticamente constante e independiente de la carga del vehículo, sirviendo las variaciones en la relación de palanca dependiendo de la carga transmitida al elemento deaccionamiento de la válvula.
