VALVOLA PER IL CONTROLLO DELLA PRESSIONE IN CIRCUITI DOPPI, IN PARTICOLARE PER IMPIANTI DI FRENI IDRAULICI.

摘要

Dual circuit pressure control valves for brake system are known in which the control pistons are located parallel to each other with each control piston controlling a different one of two brake circuits. Both control pistons are loaded by a common preloading force. The known arrangement is complicated in its construction and has a large overall length. According to the present invention, the construction is simplified and the overall length is reduced by providing a torsion spring which provides the preloading force acting on the control pistons via stationarily supported swivelling levers.
