Economic ripple effect

It manufactures a vacuum operated vehicle speed controller that minimizes the amount of air flowing into the vehicle engine manifold, and also provides speed control with convenient and safe features for safe and simple operation.

Claims (1)

A vehicle speed control device having a throttle and a vacuum source capable of moving in a direction of increasing and decreasing speed, the vacuum bellows being connected to the throttle and operating to move the throttle to an increasing position when the vacuum is increased. (100), a first valve (110) for selectively communicating with the vacuum source (108) and a vacuum bellows (100), and a second valve (operating for selectively communicating with the bellows and atmosphere) 114, a first speed signal circuit 122 for generating a signal proportional to a desired vehicle speed, a second speed signal circuit 124 for generating a signal proportional to an actual vehicle speed, and the two speeds described above. A dead-band signal circuit connected to one of the signal circuits, and the first and second speed signal circuits 122 and 124 and the dead band signal connected to the first and second valves 110 and 114. Accept signal from circuit When the vehicle speed is much lower than the set speed, the first valve 110 is communicated as described above, and when the vehicle speed is much higher than the set speed, the second valve 1 14 is communicated as described above, And a comparator circuit (126) for preventing both of the first and second valves (110) (114) from communicating in the narrow speed range determined by the control.
