ABSTRACT:
A demand type governor for gaseous fuel internal combustion engines, various kinds of breathing and heating apparatus and similar applications features a diaphragm controlled inlet valve having two different rates of opening movement for a given rate of movement of the diaphragm producing a relatively small amount of valve movement in relation to diaphragm movement for instances of lower demands and a relatively larger amount of valve movement in relation to diaphragm movement for instances of higher demands, all by means of a lever-fulcrum arrangement having a higher mechanical advantage in the first instances and a lower mechanical advantage in the second instances. Other features of the governor help assure its uniform, relatively frictionless operation, and its ease and economy of manufacture.
