Fig. 38.—“E-B” Governor
A governor and its connections are shown in [Figure 38]. The weights, R, are L-shaped, and pivoted at the angle to a plate driven by the engine. The shaft that drives the plate also supports a collar, P, that is loose on it and can slide endways; the collar rests against the short bar of the L-shaped weights. The other end of the collar touches the lever, E, which is moved when the collar moves. As the lever is connected with the throttle, a movement of the collar will control the position of the throttle.
Fig. 39.—“Case” Governor
When the shaft revolves, the long arms of the L-shaped weights tend to fly outward; this moves them on their pivots, and the short arms thereupon force the collar to slide on the shaft, which moves the lever and operates the throttle. The speed at which the throttle will begin to close is determined by the setting of the spring that holds the weights in.
Fig. 40.—“Hart-Parr” Governor
Governors and governor connections are shown in [Figures 39] and [40].
The governor shown in [Figure 41] is enclosed in a housing that can be locked or sealed. This prevents the unauthorized changing of the adjustment.
