REGULATOR DE PRESIUNE LA ROBINETUL MECANICULUI DINTR-O INSTALATIE DE FRINARE CU AER COMPRIMAT

摘要

1. A pressure controller for the driver's brake valve of an indirectly-acting compressed air brake comprising a pressure control volve which is connected to a compressed air supply line and which is actuated by a differential piston, limiting two chambers, the piston being subjected on one side to the force exerted by an adjustable spring and on the other side to control pressure characterised in that on the other side the piston is subjected additionally to said spring to an air pressure which is hold substantially constant by a pressure limiter connected to said compressed air supply line.
