Abstract:
A valve device includes a housing, a stationary disk, a drive device, a shaft and a rotor. The stationary disk is fixed at an inside of the housing and has at least one flow passage hole. The shaft is rotated about a central axis by the drive device. The rotor increases or decreases an opening degree of the at least one flow passage hole. The rotor includes: a drive disk that slides relative to the stationary disk; and a lever that is fixed to the drive disk and couples between the drive disk and the shaft. A torsion spring is placed between the shaft and the lever and urges the lever relative to the shaft in a circumferential direction around the central axis of the shaft. The shaft has a plurality of contact portions configured to contact the lever and respectively located at a plurality of locations.
