  • This disclosure relates to a valve device.
  • valve device in which a first valve plate and a second valve plate are arranged in a fluid flow path of a housing has been proposed (see, for example, Patent Document 1).
  • the first valve plate forms a first through hole and a second through hole.
  • the second valve plate forms a third through hole.
  • the second valve plate is arranged on one side in the axial direction with respect to the first valve plate.
  • the second valve plate rotates around the axis so that the third through hole communicates with at least one of the first through hole and the second through hole. For example, when the third through hole communicates with the first through hole, the fluid is discharged from the first outlet port through the third through hole and the first through hole. When the third through hole communicates with the second through hole, the fluid is discharged from the second outlet port through the third through hole and the second through hole.
  • the outlet port for discharging the fluid can be switched from one outlet port of the first outlet port and the second outlet port to the other outlet port.
  • the present inventors have focused on the reduction of the frictional force between the first valve plate and the second valve plate in the above-mentioned valve device, and examined as follows.
  • the fourth through hole constitutes a sealed area surrounded by a hole forming portion forming the fourth through hole, the second valve plate, and the bottom of the housing in the first valve plate.
  • the air When air is sealed in the sealed area, the air expands and displaces the second valve plate to one side in the axial direction at high temperatures. Therefore, a gap is formed between the second valve plate and the first valve plate. On the other hand, at low temperatures, the air shrinks and attracts the second valve plate to the other side in the axial direction. This increases the frictional force between the first valve plate (ie, the fixed valve) and the second valve plate (ie, the drive valve).
