器１１で加減して行なわれる。A portion Y surrounded by a chain line in FIG. 3 is an example of a typical conventional hydraulic rotation speed control device. In the figure, a signal pressure oil 1 proportional to the square of the rotational speed of the prime mover is transmitted to a chamber 3 having a rose 2 and moves an L bar 4 up and down. This movement is transmitted to the cup valve 5 to adjust the opening degree of the valve. On the other hand, high-pressure oil with a constant pressure flows from the inlet 6 through the orifice 7.
It reaches the upper part 8 of the cup valve 5 and transmits the pressure corresponding to the opening degree of the cup valve 5 to the signal device 9. Note that the set rotation speed is adjusted by adjusting the L-bar 10 connected to the lever 4 by a link mechanism using a manual setting device 11.
