PURPOSE:To reduce the number of parts items as well as to make improvements in assembling properties, by making a valve disc inside a valve controlling an actuator driving an air flow passage selecting door controllable directly with a pushbutton switch, while forming a flow passage selecting land in the valve disc itself. CONSTITUTION:A valve body 15 is set up at the back of a control panel 11 provided with a temperature adjusting level 12, an air quantity adjusting switch 13 and plural pieces of mode selecting pushbutton switches 14. Inside this valve body 15, guide holes 16 are made up in accordance with the position and number of pushbutton switches 14, and each of interlocking plates 17 to be connected to each switch 14 are inserted into the inside of each guide hole 16. The other end of each interlocking plate 17 is coupled with a valve disc 20 supported by a support frame 19 via a rising part 21. Then, with slide displacement of the valve disc 20 through these interlocking plates 17, a mode door hole 32 to be interconnected to an actuator 39 controlling a flow passage selecting door 38 is made up so as to be alternatively interconnected to a suction pressure hole 31 or an atmospheric hole 33. |
