Abstract
A valve device includes a temperature sensor disposed to project from a housing to a tank inner space to detect the temperature in the tank inner space, and can detect the temperature without being influenced by the heat capacity of the housing. A coil generates a magnetic force to drive a valve with three terminals arranged at different positions in an axial direction, and a drive voltage is selectively applied between two of the terminals. A current value of the driving current which energizes the coil can be changed by selecting the terminals between which the drive voltage is applied. Without controlling the drive voltage, it is possible to suppress wasting power such that the driving current of the large current value is generated in the start-up time, and the current value of the driving current is decreased in the holding time.
