Abstract: The present invention is a flow-rate adjustable valve for adjusting a flow rate of liquid flowing through a flow path. The flow-rate adjustable valve includes: a main valve body; a back pressure chamber; an inlet hole; an outlet hole; a pilot valve body for opening and closing an end of the outlet hole on a side of the back pressure chamber; an elongated member holding the pilot valve body; and a lifter rotatable and also movable in the axial direction of the elongated member by the rotation of the rotatable member. The lifter and the elongated member are integrally movable in the axial direction. The elongated member is connected to the lifter under a condition in which the elongated member is biased to the lifter in a one-way direction of the axial direction by a biasing-connecting member.

Abstract: The present invention is a flow-rate adjustable valve for adjusting a flow rate of liquid flowing through a flow path. The flow-rate adjustable valve includes: a rotatable member; a lifter linearly movable by a rotation of the rotatable member; a valve body linearly movable by a linear movement of the lifter; a stopper configured to restrict a movable range of the lifter in a fixed state of the stopper in which a position of the stopper is not able to be changed; and a stopper-holding member configured to hold the stopper selectively in the fixed state or in a provisional fixed state in which the position of the stopper is able to be changed.

Abstract: The cylinder body is affected by a rotational operation of the first operation part in such a manner that a rotational position of the cylinder body is changed while an axial position of the cylinder body is not changed, and is affected by a rotational operation of the second operation part in such a manner that the axial position of the cylinder body is changed while the rotational position of the cylinder body is not changed. A communication amount between the cold water supply channel and the cold water inlet hole, a communication amount between the hot water supply channel and the hot water inlet hole, and/or a communication amount between the mixed water outlet hole and the mixed water outlet channel are/is changed depending on the axial position and the rotational position of the cylinder body in order to achieve both a temperature regulation and a flow rate regulation.

Abstract: An automatic water faucet device 1 includes: an electrolysis tank 37 that electrolyzes water to generate electrolyzed water; a second water discharge part 13 for discharging the electrolyzed water, a second flow path 18 that extends from the electrolysis tank 37 to the second water discharge part 13; a second solenoid valve 28 that switches between supply and blocking of normal water with respect to the electrolysis tank 37, and a controller 40 that controls the electrolysis tank 37 and the second solenoid valve 28. The controller 40 energizes the electrolysis tank 37 to discharge the electrolyzed water and thereafter stops the energization of the electrolysis tank 37 and maintains an open state of the second solenoid valve 28, to stop the supply of the electrolyzed water to the second flow path 18 and to supply normal water to the second flow path 18.
