ABSTRACT:
A fluid brake control system is provided including a brake control pipe and a control valve comprising a quick action chamber and an emergency slide valve operable from a normal to a service brake position in response to service reduction in brake pipe pressure, the emergency slide valve having a fluid pressure differential operated abutment disposed between a first pressure chamber within a housing on one side of the abutment subject to pressure of the quick action chamber, and a second pressure chamber contained in a housing cover on the other side of the abutment connected by a passage to the brake pipe. The cover includes quick action control apparatus including a quick action poppet type valve operably connected to the abutment for actuation of the quick action valve by the abutment from a normally closed to an open position in response to the operation of the abutment in one direction to a service braking position. The quick action poppet type valve vents fluid from the brake pipe when it is opened.
