    摘要： In a compressed air operated braking system in which the brake motors are fitted with lock actuators and in which the compressor incorporates unloader means actuated by a governor valve responsive to reservoir pressure, movement of a control member to render the lock actuators inoperative also effects delivery of compressed air to the governor valve to augment the spring loading thereof and so temporarily establish a higher pressure in the system for releasing the lock actuators.
