Abstract: A shower apparatus reduces the effects of water hammer within a portion of a flow route connecting a shower head to a supply, when a flow adjusting mechanism proximal the shower head is operated. The shower apparatus adjusts pressure of a supply fluid dependant upon the degree of throttling of the flow route and the flow adjusting mechanism controls the amount of flow of the supply fluid dependant upon a degree of opening thereof to the discharge end of a shower head. The structure providing the pressure adjustment and the flow adjusting mechanism are each disposed successively from upstream of the flow route, between a shower side flow route provided in a water plug and the shower head or a discharge end of the shower head.

Abstract: 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).

Abstract: A temperature-actuated valve device which comprises a body 5 provided with a fluid inlet opening 6b and a fluid outlet opening 5a, a vale seat 5b formed on the peripheral edge of the outlet opening 5a, a main valve body 8 which is disposed movably within the body 5 in the flow direction of fluid and which is brought into and out of an abutting engagement with the outlet opening 5a to perform the opening and closing operation, a pilot valve body 7 which is disposed movably within the body 5 in the same direction as the direction of movement of the main valve body 8 and which is of a tubular shape causing a change in the fluid pressure acting on the upstream side or the downstream side of the main valve body 8, and a temperature-actuated spring 11 which is linked to the pilot valve body 7 and which deforms when it reaches a predetermined temperature and above.

Abstract: A valve device using pipe materials in which a fluid control mechanism is arranged and which comprises a valve device body (11) made of a metallic pipe material and having a tubular flange (21) integrally formed on the outer surface of the body so as to protrude therefrom, and a tubular member (12) for forming a flow passage, which is fitted and connected at the base end thereof to the top end of the tubular flange (21). The tubular flange (21) is formed so that the area of the opening at the base end thereof communicating with the flow passage within the valve device body is greater than the area of the opening at the top end of the tubular flange. The inner peripheral portion (21a) of the base end of the tubular flange (21) is formed with a smoothly curved surface, and the flow passage is formed along such a curved surface.

Abstract: In a combination faucet device (10) according to the invention, a movable valve member (160) slidingly moves relative to a main casing (30) to change a mixing ratio of high-temperature water supplied from a hot water port (116) to low-temperature water supplied from a cold water port (106). The movable valve member (160) is pressed by a temperature sensitive spring (130) in a first direction while being pressed by a bias spring (150) in a second direction opposite to the first direction. The temperature sensitive spring (130) is exposed to a water mixture and varies its spring constant according to the temperature of the water mixture. The temperature sensitive spring (130) accordingly moves the movable valve member (160) in a direction for decreasing the ratio of the high-temperature water to a certain position where the spring force of the temperature sensitive spring (130) balances with the spring force of the bias spring (150), thus allowing a water mixture adjusted to a target temperature.

Abstract: A hot and cold water mixing device which comprises an inner housing (11) provided with a hot water inlet hole (17), a cold water inlet hole (18) and a mixed water delivery hole (19), and an outer housing (31) having openings (33, 34, 32) communicating with a hot supply passage (15), a cold water supply passage (16) and a mixed water supply passage (14). The inner housing (11) is inserted into the outer housing (31) to form a hot water passage (20), a cold water passage (35) and a mixed water passage (30) between the outer housing (31) and the inner housing (11). The hot water passage (20) and the mixed water passage (30) are formed by enclosing the hot water inlet hole (17) and the mixed water delivery hole (19) by the respective seal members (26, 29) which each are partly arranged so as to intersect with the circumferential line of the inner housing (11).

Abstract: An automatic temperature control means 16 for automatically generating a mixed warm water of prescribed temperature by mixing an introduced hot water from a hot water inflow passage 14 and an introduced cold water from a cold water inflow passage 12 with each other at a flow rate ratio corresponding to the prescribed temperature, and a flow rate control means 19 for regulating the temperature of the discharged mixed warm water by mixing it with a hot or cold water introduced from the hot or cold water inflow passage 14 or 12 through a by-pass 18 around the former means are provided. As a result, mixed warm water of desired temperature can be easily obtained by manipulating the flow rate control means 19.

Abstract: A bubbly water outlet device comprises a swirl chamber which is connected to a water supply source and is adapted to swirl a flow, and a bubbler chamber which is connected to the swirl chamber through a discharge port provided substantially at a center of the swirl chamber. The bubbler chamber is adapted to suck air from an exterior by virtue of the inflow of water from the discharge port and is capable of discharging bubbly water.
