Abstract
A brake exhaust valve having a primary gate driven in translation between open and closed positions by an actuator rod connected to the primary gate and a waste gate. The waste gate is rigidly connected to the actuator rod, and is arranged to unload pressure on the primary gate and develop impact energy before the primary gate is struck for reliability in opening and closing of the primary gate. A waste seal carried by the waste gate in a manner permitting it to float to a limited degree relative to the waste gate assures a positive seal with a waste port in the primary gate regardless of misalignment between the primary gate and actuator rod.
