Abstract

PURPOSE:To control below the set rotation number even when the governor mechanism may not be normally actuated, by the sub-governor valve which is separately set up from the governor mechanism. CONSTITUTION:A lever 6 is allowed to be rotated with inclination to the outside direction by means of being contacted to the inner surface of the outer end part of the lever 6 by the top end of a sub-governor when the sub-governor 8 is projecting from a sub-governor cylinder 8a by the centrifugal force of a rotor 2, and thereby an air supplying hole A is sealed by means of rotating a valve 5 by the actions of each energyzed springs 7 by slipping off the claw 6a of the lever from a knotch 4C. In a case when the governor mechanism 10 is in normal operation, the actuating rotation number of the sub-governer is set a little higher than the max. rotation set constant by the governor mechanism, so as not to be acted by the sub-governor of this safety device.
