Abstract

In un complesso frenante a regolazione elettronica, azionato mediante fluido a pressione, per almeno un circuito frenante di un autoveicolo in cui in un tubo di controllo derivato da un tubo di mandata nel circuito frenante principale e che porta ad una valvola a 3/2 vie controllabile è inserita una valvola elettromagnetica a 2 vie attivabile tramite una linea elettrica di comando e, garantendo un massimo grado di sicurezza dei freni per un impiego ancora più universale del dispositivo di frenatura in autoveicoli con diversi sistemi di frenatura, la valvola elettromagnetica a 2 vie viene attivata tramite un circuito logico solo quando nel dispositivo di regolazione elettronico del dispositivo di frenatura vi sono determinate condizioni funzionali e di regime, per l'aumento della rapidità di reazione del dispositivo di frenatura viene proposto di strutturare la valvola a 3/2 vie come valvola a rapporto di compressione e la valvola elettromagnetica a 2 vie come valvola elettromagnetica a 4/2 vie e di inserire questa valvola in un tubo di controllo derivato dal tubo di mandata del circuito frenante secondario e che porta pure alla valvola a rapporto di compressione.In an electronically regulated brake assembly, operated by means of pressure fluid, for at least one brake circuit of a motor vehicle in which in a control tube derived from a delivery tube in the main brake circuit and which leads to a 3/2 way valve controllable, a 2-way electromagnetic valve can be activated and activated via an electric control line and, ensuring a maximum degree of brake safety for an even more universal use of the braking device in vehicles with different braking systems, the 2-way electromagnetic valve it is activated via a logic circuit only when there are certain functional and steady-state conditions in the electronic regulation device of the braking device, to increase the speed of reaction of the braking device it is proposed to structure the 3/2 way valve as compression ratio valve and 2-way electromagnetic valve as an electromagnetic valve a 4/2 way and to insert this valve in a control tube derived from the delivery pipe of the secondary brake circuit and which also leads to the compression ratio valve.
