摘要： VALVULA DE FRENO DE DOBLE CIRCUITO, QUE ESTA PROVISTA DE UN MECANISMO DE REGULACION DE LA DIFERENCIAL DE IMPULSION, QUE REGULA LA DIFERENCIAL ENTRE LAS PRESIONES DE IMPULSION DE LOS CIRCUITOS PRIMARIO Y SECUNDARIO DE LOS FRENOS. EL MECANISMO REGULADOR DE DIFERENCIAL INCLUYE UN RETENEDOR DE MUELLE QUE SE MONTA EN EL EXTREMO DEL VASTAGO DE UNA VALVULA DE RELE Y QUE ALOJA A UN NUCLEO MOVIL ACCIONADO POR RESORTE. EL NUCLEO MOVIL SE PONE EN CONTACTO CON EL ELEMENTO DE ACCIONAMIENTO, DURANTE EL FUNCIONAMIENTO DE LOS FRENOS, PARA TRASLADAR LA FUERZA DEL MUELLE AL ELEMENTO DE RELE Y, POR LO TANTO, A LOS ELEMENTOS DE VALVULA DEL CIRCUITO SECUNDARIO. ESTE TRASLADO DE LA FUERZA DEL MUELLE REDUCE LA PRESION DE INICIACION DE APERTURA DE LOS ELEMENTOS DE VALVULA, REGULANDO LA COMUNICACION A TRAVES DEL CIRCUITO SECUNDARIO, PARA REDUCIR ASI LA DIFERENCIAL ENTRE LAS PRESIONES GENERADAS EN LOS CIRCUITOS PRIMARIO Y SECUNDARIO.

摘要： A dual circuit brake valve is provided with a delivery differential control mechanism which controls the differential between the delivery pressures of the primary and secondary braking circuits. The delivery differential control mechanism includes a spring retainer which is mounted on the end of the stem of the relay valve and which receives a spring-biased plunger. The plunger engages with the actuating member during the brake application to thereby transfer the force of the spring to the relay member and therefore to the valve members of the secondary circuit. This transfer of the spring force reduces the crack open pressure of the valve members controlling communication through the secondary circuit, to thereby reduce the differential between the pressures generated and the primary and secondary circuits.

摘要： A dual circuit brake valve includes a plunger assembly (20) carrying the primary valve seat (48), and the primary valve poppet (44) within the primary piston (20). A pair of axially-spaced, circumferentially extending bearing members (24, 26) extend from the primary piston (20) slidably engaging larger and smaller diameter portions (l6, l8) of the bore (l4) of the housing (l2) to thereby guide the primary piston (20) independently of other components within the housing (l6). The secondary set of valve members (92, l00, l06) is actuated by a relay piston (76) which is similarly guided in larger (80) and smaller (72) diameters of the bore (l4) independently of other components within the valve housing (l2). The primary piston (20) defines a pressure effective area due to the difference in the larger and smaller portions (24. 26), so that inlet port pressure acting on the effective area yieldably urges the primary piston (20) toward the brake released position.
