FAUCET VALVE DEVICE

Japanese Patent JP2022055971

A

To provide a faucet valve device suitable for actualizing the electrification of both temperature control and flow control.SOLUTION: The faucet valve device includes: a water side auxiliary pipe member one side of which is stored in a water supply path and the other side of which can abut on the peripheral wall of a cylinder body and communicate with a water inflow hole; and a hot water side auxiliary pipe member one side of which is stored in a hot water supply path and the other side of which can abut on the peripheral wall of the cylinder body and communicate with a hot water inflow hole. The water side auxiliary pipe member can abut on the peripheral wall of the cylinder body and communicate with the water inflow hole in response to a water pressure difference between the one side and the other side, and the hot water auxiliary pipe member can abut on the peripheral wall of the cylinder body and communicate with the hot water inflow hole in response to a water pressure difference between the one side and the other side. In accordance with the axial position and the rotation position of the cylinder body, the communication amount of the water side auxiliary pipe member with the water inflow hole, the communication amount of the hot water auxiliary pipe member with the hot water inflow hole, and/or the communication amount of a hot water outflow hole with a hot water outflow path is changed to actualize both temperature control and flow control.SELECTED DRAWING: Figure 7
