Mi— views show only the ports andpassages in use during the time thevalves are in the particular positiondesignated and this will avoid confusionand the possibility of mistakes that mightoccur if all of the various ports, pas-sages and cavities were shown in eachindividual view. As the past issue contains quite a com-neral description of the construc-tion and operation of the brake and states over valve is in empty car position, thetriple valve performs the functions of anyordinary K triple valve as but one brakecylinder and one reservoir are in usetherefore retarded release, full serviceand emergency positions of the triplevalve are shown with change over valvein load position, but for comparison theslight difference between full service andquick service positions is shown with thechange over valve in empty positio
