Abstract

Perfeccionamientos en moduladores de presión de fluidos para sistemas de frenos antiderrapantes, del tipo de modulador constituido por un caja provista de un orificio de entrada, un orificio de salida y un orificio de desahogo, una primera cámara que se conecta al orificio de entrada mediante un primer conducto que contiene una primera constricción, al orificio de salida mediante un segundo conducto y al orificio de desahogo mediante un tercer conducto, una válvula controlada electromagnéticamente que se aloja en la primera cámara y es empujada por un primer dispositivo resiliente a una primera posición en la que cierra el tercer conducto y abre el primer conducto, cuya válvula puede ocupar bajo la influencia de un elemento magnético que contraresta la acción del primer dispositivo resiliente, una segunda posición en la que abre el tercer conducto y cierra el primer conducto, caracterizados porque se dota a cada modulador de una segunda cámara puesta en comunicación con el orificio de entrada, un cuarto conducto que comunica la segunda cámara con el orificio de salida y pone en derivación la primera constricción y la primera cámara , una segunda válvula alojada en la segunda cámara y empujada por un segundo dispositivo resiliente a una posición abierta, siendo empujada la segunda válvula a un posición cerrada por un pistón sensible a la presión del fluido en una cavidad que se comunica con el tercer conducto entre la primera camara citada y una segunda constricción, siendo sensible la segunda válvula, al estar en su posición cerrada, a las presiones del fluido en la segunda cámara y el cuarto conducto que actúan respectivamente, sobre una u otra de sus caras.
