Releasing. In releasing the brakes after an application, , the air in chamber B of the emergency valve is exhaustedthrough ports A: and k, cavity M of slide valve 25, and port I to thestraight air pipe, thence through ports n, o, and p in the rotaryvalve seat 2, cavity h and port j in the rotary valve, and port m tothe atmosphere through the exhaust pipe. The greater pressure inchamber R then forces the equalizing piston to release position,uncovering the exhaust ports x and u and allowing the air from thebrake cylinder to
