Abstract: A valve device has a pressure chamber, which is connected to a liquid inlet and a liquid outlet and retains liquid, and a pressure regulator decreasing the pressure in the pressure chamber to a predetermined level. The pressure regulator has a pressure receiving member. When the pressure in the pressure chamber becomes lower than the predetermined level, the pressure receiving member is elastically deformed in an inward direction of the pressure chamber. The pressure regulator generates actuation force greater than the pressing force produced by the elastic deformation of the pressure receiving member. The pressure regulator is configured to be opened by the actuation force. When the pressure regulator is open, a fluid supply from the liquid inlet to the pressure chamber is permitted. It is thus possible to minimize the valve device.
