  • Adjustable centrifugal governor speed control
    Patent number: 9470232
    Abstract: A rotational speed governor for an air motor comprises a housing, a valve, a shaft, a cross-bar, a plate and a pair of weights. The housing has an air inlet and an air outlet. The valve is disposed between the air inlet and the air outlet. The shaft extends along an axis within the housing. The cross-bar is connected to the shaft. The plate intersects the shaft between the valve and the crossbar. The weights are rotatably connected to the crossbar at pivot points. Each weight comprises an arcuately profiled edge extending beyond the crossbar to engage the plate. The arcuately profiled edges are shaped to increase a moment arm on the plate as the weights pivot away from the shaft.
