使われるようになる。 When the water temperature is low (for example, 30° C. or lower as shown in FIG. 5), when the second solenoid valve 74 is released (ON), the first negative pressure chamber 721 and the second negative pressure chamber are separated as shown in FIG. Negative pressure is introduced to both the first diaphragm 712 and the second diaphragm 713.
Both are suctioned, and the actuating rod 705 is moved by the second stroke St2. In this case, by sliding between the movable member 718 and the support member 717, the acting force of the two negative pressure chambers 721 and 722 can be applied in two stages, and the damper 71 is fully opened and the heater 2 is turned on. Enough warm air to the engine intake pipe 4
5 and promotes vaporization of the injected fuel to facilitate ignition, smooth engine starting, and warm-up. When the water temperature further rises (for example, from 30 to 60°C as shown in FIG. 5), if the first solenoid valve 73 is opened (ON), the third solenoid valve 73
As shown in the figure, negative pressure is introduced into the first negative pressure chamber 721, the first diaphragm 712 is sucked, and the actuating rod 705 is moved by the first stroke St1.
The opening degree of the damper 71 becomes slightly smaller, and a slightly smaller amount of warm air from the heater 2 is sucked into the engine intake pipe 45 to promote warm-up. When the water temperature further increases (for example, 60° C. or higher as shown in FIG. 5), the damper 71 closes and all of the hot air from the combustion heater 2 is used for heating.
