合に一比べて小さいか又は正圧になり、この負圧ではア
クチュエータを十分に作動させることはできなかった。In conventionally proposed actuators for constant speed traveling devices (for example, Japanese Utility Model Publication No. 15886/1986), the servo motor of the actuator is operated by negative pressure in the intake pipe. In the case of a normal engine, the negative pressure in the intake pipe is large, so the actuator can be operated sufficiently, but in the case of a supercharged engine, the negative pressure is smaller or more positive than in the case of a normal engine. The actuator could not be operated sufficiently with this negative pressure.

、車両は定速走行できる。Therefore, the diaphragm moves to the left against the spring (2), and the throttle valve (5) opens via the rod (2) and the wire (3).The opening of the throttle valve (5) causes the vehicle to speed up. When the vehicle speed increases and reaches the set vehicle speed, this signal is input to the computer, which issues a command to the llinear motor (+51) to close the pulp. Therefore, the pulp (16) αη is closed, and the positive pressure chamber (21) and negative pressure chamber (21) are closed. The positive pressure and negative pressure in the pressure chambers (221) are maintained at the same level at the set vehicle speed because each of the chambers (20 (b)) is sealed, and the diaphragm Q51 is connected to the spring holder and the positive and negative pressures in each of the chambers. The throttle valve (5) remains at a position balanced with the negative pressure, and the throttle valve (5) maintains a constant opening state, allowing the vehicle to run at a constant speed.

前記下流側の負圧が小さい等の要因は、本発明のアクチ
ュエータの作動には全く障害となるようなことはない。Since the present invention is configured as explained in detail above,
Even if the negative pressure downstream of the throttle valve in a supercharged engine is unstable because it is small or close to positive pressure, it does not directly introduce the negative pressure like conventional actuators. The actuator is actuated by the pressure difference between the upstream and downstream sides of the throttle valve.
Factors such as the small negative pressure on the downstream side do not impede the operation of the actuator of the present invention at all.

くすることができるため、省エネルギーとなる。In addition, since the present invention uses the pressure difference on both sides of the throttle valve, the engine pressure required to move the actuator is lower than in the past, which extracts negative pressure only from the downstream side of the throttle valve, which reduces engine horsepower savings. This can save energy.
