Abstract

1512701 Load responsive braking systems WESTINGHOUSE BRAKE & SIGNAL CO Ltd 11 Dec 1975 [8 Feb 1975] 5450/75 Addition to 1402822 Heading F2F An empty/load brake control valve apparatus includes a brake pressure input port 5, a brake cylinder output port 7 and a port 9 connected to an extra reservoir 10, a cut-off valve 11 between ports 5 and 7 operable by plunger 12 responsive to the difference between the pressures at ports 5 and 9, a further valve 17 controlled by fluid pressure from an empty/load sensing device 25 and which holds closed a passage, between the brake cylinder output port 7 and the extra reservoir port 9, which is open for a loaded condition and a valve 23 for venting reservoir 10 during a brake application if the brake cylinder pressure falls below a prescribed value.
