摘要: A safety control mechanism operable for shutting off operating air flow to the motor of a grinding tool when the motor overspeeds beyond a rated governor controlled maximum, including a trip pin normally pressing a leaf spring valve from a closed condition to an open condition and adapted to be tripped by means of a centrifugally operable flyweight to release the valve to closed condition when the motor overspeeds, whereby operating air to the motor is shut off.
