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.

Flow-rate adjustable valve

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.

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 movably supported in the flow path via a diaphragm membrane; a back pressure chamber; a plurality of inlet holes communicating the upstream side of the flow path with the back pressure chamber; an outlet hole communicating a downstream side of the flow path with the back pressure chamber; and a pilot valve body for opening and closing the outlet hole, wherein moments acting on the main valve body based on the liquid flowing into the back pressure chamber through the plurality of inlet holes are canceled by each other in total, under a condition in which the pilot valve body opens the outlet hole.

A touch detection device has a sensing unit that includes a contact portion which comes into contact with an object, a vibration excitation element that vibrates the contact portion, a detection circuit that includes a drive circuit and a contact determination circuit, and an electrical wire that connects the vibration excitation element and the detection circuit, and is covered with a covering material. The vibration excitation element is covered with a potting layer made of resin through a predetermined internal space. While being inserted into the potting layer, the electrical wire has an end connected to the vibration excitation element, and an insertion portion inserted into the potting layer includes a non-covering portion formed by peeling of the covering material.

Touch detection device for water handling equipment, and faucet apparatus including the same

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.

Faucet apparatus

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.

Thermally actuated hot and cold water mixing valve configured to minimize valve hunting

The hot and cold water mixing valve having a cylindrical casing is provided with a control valve member which adjusts a ratio between hot and cold water inlets by balancing loads applied by a biasing member and an actuator, and cylindrical temperature adjuster which adjusts a position of the control valve member when rotated. In the temperature adjuster, an upper surface is formed at one end, a knob is provided in the center of the upper surface, and a ring-shaped recess is formed around the knob at the upper surface. The temperature adjuster is arranged inside the casing and the knob is inserted, coaxially with the casing, into the hole which opens at one end of the casing. A spacer which covers the recess is interposed and held between the upper surface of the temperature adjuster and one end of the casing.

A switching valve assemblyfor use in a mixing faucet is disclosed. The switching valve assembly comprises a switching valve assemblyfor use in a mixing faucet, which comprises a manual operation memberadapted to be moved in response to a pressing operation by a user, a push rodhaving a base end joined to the manual operation member, a pilot valvedisposed relative to a distal end of the push rod, a coil springinterposed between the pilot valve and the distal end of the push rod, a diaphragm main valvehaving a pilot-valve port designed such that the pilot valve is selectively brought into contact therewith and separated therefrom, a pressure chamberformed on the side of a back surface of the main valve to contain a part of the push rod, the pilot valve and the coil spring, and a valve seatdesigned such that a front surface of the main valve is selectively seated thereon and unseated therefrom.

Opening and closing valve

A pressure reducing valve comprises a valve support member provided with a water passage, a valve seat fitting on the portion of the valve support member primary side relative to the secondary side end of the water passage, a cup-shaped valve body fitting on the secondary side end of the valve support member to slide and capable of abutting the valve seat at the open end, while enclosing the secondary side end of the water passage at the cylindrical portion, a seal member for sealing the sliding contact part between the valve support member and the valve body, and a resilient member disposed in the valve body to force the valve body away from the valve seat.

Shower apparatus

A hot and cold water mixing device which comprises one or more valve units each constituted by accommodating an operating member within a hollow casing, and a housing into which the one or more valve units are inserted and arranged and in which two primary water passages communicating with a hot water supply source and a cold water supply source, respectively, are formed. The housing is composed of an outer housing (1) and an inner housing (2) which is inserted into the outer housing and which is formed with water holes (11,12,13) communicating with said valve units, and at least two primary water passages (5,6) are formed between the outer housing and the inner housing by separating members (3). Further, since the hot water passage (5) and the cold water passage (6) are formed between the outer casing (1) and the inner housing (2) using separating members (13), the primary water passages can easily be formed and, simultaneously, the construction of the mixing device can be simplified and the assembling and disassembling operations can be facilitated.
