VALVE DEVICE
In a valve device, a rotor includes a drive disk and a lever fixed to the drive disk. The lever couples between the drive disk and a shaft. In the valve device, a first torsion spring is placed between a housing and the shaft, and a second torsion spring is placed between the shaft and the lever. A...

| description | In a valve device, a rotor includes a drive disk and a lever fixed to the drive disk. The lever couples between the drive disk and a shaft. In the valve device, a first torsion spring is placed between a housing and the shaft, and a second torsion spring is placed between the shaft and the lever. A drive device includes an electric motor configured to drive the shaft in a rotational drive range, which is between an initial rotational position and a maximum rotational position, in a first rotational direction toward the initial rotational position and a second rotational direction opposite to the first rotational direction. The first torsion spring urges the shaft relative to the housing in the second rotational direction in the state where the shaft is placed in the initial rotational position upon the rotation of the shaft in the first rotational direction. |
