Patent ID: 8878383

Claim:
A faucet device configured to drive a solenoid valve by electrical power from a built-in generator to switch between water stopping and water spouting, comprising: a device body; a solenoid valve disposed within the device body, and adapted to switch between water stopping and water spouting; a spout port forming portion formed with a spout port, and adapted to cause water that passes through the solenoid valve to be spouted; an impeller-driven generator equipped with an impeller, a power generating magnet and a power generating coil, and adapted to rotate the impeller by flow of water that passes through the solenoid valve to generate electrical power for driving the solenoid valve; a solenoid valve-side water-passage forming member for guiding water that passes through the solenoid valve to the generator; a spout port-side water-passage forming member for guiding water that passes through the generator toward the spout port; a first elastic member for ensuring water-tightness between the solenoid valve-side water-passage forming member and the generator and allowing relative displacement between the solenoid valve-side water-passage forming member and the generator; a second elastic member for ensuring water-tightness between the spout port-side water-passage forming member and the generator and allowing relative displacement between the spout port-side water-passage forming member and the generator; a third elastic member for coupling the solenoid valve-side water-passage forming member to the device body and allowing relative displacement between the solenoid valve-side water-passage forming member and the device body; and a fourth elastic member for coupling the spout port-side water-passage forming member to the device body and allowing relative displacement between the spout port-side water-passage forming member and the device body.
