Governor valve

الوصف

The  governor  valve senses  engine  speed (transmission output shaft speed) to help control gear shifting.  The  governor  gear  is meshed  with  a  gear  on  the  transmission  output  shaft.Whenever the vehicle and output shaft are moving, thecentrifugal weights rotate. When the output shaft andweights are spinning slowly, the weights are held in bythe governor springs, causing low-pressure output andthe  transmission  remains  in  low  gear.  As  the  enginespeeds  increases,  the  weights  are  thrown  out  furtherand   governor   pressure   increases,   moving   the   shiftvalve and causing the transmission to shift into highergear.
