The disc is also subjected to centrifugal forcewhich maintains a certain tension on the spring and a fixedpoint of cut-off when the speed reaches the pre-determinedlimit and acts with the inertia of the disc in varying thecut-off when the speed ischanged. It has come to be uni-versally acknowledged that the regulation of high speedengines with fly-wheel cut-offs is superior to that whichcan be obtained with any other form of governor, and theapplication of this form of governor for tripping the valvesof a disengaging cut-off is a creditable advance in thisbranch of steam engineering. In this particular engine the governor is located in the 107.—HALF SECTION.
