ABSTRACT:
A housing has a triple valve coaxially adjoining a proportioning piston valve end-to-end, the triple valve having supply, lap and exhaust positions for governing pressure in a brake cylinder; and the proportioning piston valve being operable to sense an emergency signal in a brake pipe for delivering fluid from an emergency reservoir to the brake cylinder after the brake cylinder has been charged to substantially service pressure from an auxiliary reservoir. The triple valve and the proportioning valve piston are biased in opposite directions by the same biasing spring.
