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: A hot and cold water mixing valve including a temperature adjusting dial, and a cylindrical casing having formed therein a hot water inlet and a cold water inlet is provided with a control valve member in which one end thereof is subjected to a load from a biasing member and the other end is subjected to a load from an actuator. By balancing between the loads applied by the biasing member and the actuator, a mixture ratio between the hot water which flows in through the hot water inlet and the cold water which flows in through the cold water inlet is adjusted. A temperature adjuster adjusts a position of the control valve member through the biasing member and includes a tapered skirt portion, which spreads in a radial direction, at an end on the control valve member side thereof.

Abstract: A faucet apparatus includes a rotating operation unit that rotationally operates water spouting and shutting off operations, and a flow adjustment operation and a temperature adjustment operation of hot and cold water, an acceleration sensor that detects an attitude and a rotating movement of the rotating operation unit, and a control unit. The rotating operation unit moves without striding across a horizontal plane at a time of performing a rotating operation from a first operation position to a second operation position around a predetermined rotation axis in the water spouting state. The acceleration sensor is set in a state where a rotation axis at a time of rotating within a predetermined plane in response to the flow adjustment operation and temperature adjustment operation of the hot and cold water does not coincide with a gravity direction axis.
