Abstract:
In a centrifugal r.p.m. regulator for internal combustion engines, the governor sleeve is connected to a fuel quantity control member through a linkage assembly that includes an intermediate lever coupled to a manually operable lever to arbitrarily adjust said fuel quantity control member. The r.p.m. regulator includes a spring-loaded support arm against which the governor sleeve is adapted to abut after traveling a predetermined distance under the force exerted by the centrifugal weights as the engine r.p.m. increases. Beyond a predetermined r.p.m. the last-named force overcomes the force of the support lever spring thus permitting the governor sleeve to be further displaced, shifting thereby said control member to lessen the injected fuel quantities.
