Valve device, pressure regulator, carriage, liquid ejecting apparatus and method for manufacturing valve device

A carriage comprising:

• a pressure chamber connected to a liquid inlet and a liquid outlet for retaining liquid;
• a pressure regulator decreasing the pressure of the liquid in the pressure chamber to a predetermined level;
• and
• a liquid ejection head;
• wherein:
• the pressure regulator has a pressure receiving member, the pressure receiving member being elastically deformed in an inward direction of the pressure chamber when the pressure in the pressure chamber becomes lower than the predetermined level, the pressure regulator generating actuation force greater than pressing force produced by the elastic deformation of the pressure receiving member, the pressure regulator being configured to be opened by the actuation force, a fluid supply from the liquid inlet to the pressure chamber being permitted when the pressure regulator is opened,
• wherein the carriage includes a pressing member generating the actuation force by receiving the pressing force,
• wherein the pressing member functions as a cantilever.

A valve device having a pressure chamber connected to a liquid inlet and a liquid outlet for retaining liquid and a pressure regulator decreasing the pressure in the pressure chamber to a predetermined level, wherein:

• the pressure regulator has a pressure receiving member, the pressure receiving member being elastically deformed in an inward direction of the pressure chamber when the pressure in the pressure chamber becomes lower than the predetermined level, the pressure regulator generating actuation force greater than a pressing force produced by the elastic deformation of the pressure receiving member, the pressure regulator being configured to be opened by the actuation force, a fluid supply from the liquid inlet to the pressure chamber being permitted when the pressure regulator is opened,
• the valve device including a pressing member generating the actuation force by receiving the pressing force,
• the pressure regulator including a valve body to close the liquid inlet,
• the pressing member being formed by a plate, the pressing member including a pressing portion for contacting and pressing the valve body, and the pressing portion having a channel-like cross-sectional shape.
