Abstract: A plunger-type diaphragm valve is disposed in an accommodation trough of a flush device. The accommodation trough communicates with an inlet passage and an outlet passage. The valve includes a control unit. One end of the control unit is provided with a diaphragm member and an engaging member, and another end leans against the outlet passage to block the inlet passage and the outlet passage. An outer wall of the diaphragm member is fixed to the accommodation trough. The diaphragm member has a curved portion. When the valve is actuated, the curved portion is deformed by water pressure to bring the control unit to move away from the inlet passage for the inlet passage to communicate with the outlet passage. The stressed area of the diaphragm member is small and the deformation is less, so the diaphragm member won't wear. The valve is durable and has a long life.

Abstract: A manual/automatic and cold/hot faucet with a ceramic valve includes a main body adopting a ceramic valve that is connected with an automatic water exit passage and a manual water exit passage. The ceramic valve has a fixing member and a sliding member, with the sliding member sliding against the fixing member to command water to flow into the automatic water exit passage or the manual water exit passage. So the faucet can give water automatically or manually. As the ceramic valve is excellently resistant to abrasion, the present faucet can thus be durable, not apt to get leaked.

Abstract: A manual pressing device for a flusher includes a stop ring, a pressing rod unit, a spring, and a nut. The manual-pressing device is located in a lateral hole of the body of a flusher, normally stopping water in the flusher or pressed to connect a lengthwise hole in the body with a water-exhausting passageway for flushing water. The nut screws with the body to keep the stop ring, the pressing rod unit and the spring stably combined in the lateral hole. When the pressing member of the pressing rod unit fitted with an outer end of the pressing rod is pressed inward, the annular leak recess of the pressing rod unit may communicate with the water exhausting passageway to let water flow therethrough so as to flush water, and releasing the pressing member pressed makes the pressing rod return to its original position to block the water exhausting passageway.

Abstract: A double valve flusher includes a body, a separating plate, an upper and a lower valve base, a movable valve, a film valve, a fixing member, and an electromagnet. An upper leak room is formed between the film valve and the upper valve base. A leak room is formed between the separating plate, the lower valve base and the movable valve contained in a chamber in the body. The upper leak passageway in the upper leak room and the upper valve base is blocked or opened by the core of the electromagnet, thus controlling the film valve in disfiguring to block or open the leak passageway of the leak room and the lower valve base. Then the movable valve is controlled to move up and down to flush or stop flushing water into a urinal where this flusher is positioned.

Abstract: A solenoid valve includes a valve seat with a hole, a magnetically conductive hollow winding reel, an induction coil unit wound around the reel, a permanent magnet fixed on the reel, and a magnetically insulating vertical tube disposed within the reel. A moving core is biased by a spring to a lower limit position so as to close the hole, thereby preventing water flow though the hole. A magnetic fluid is filled within a sealed gap between the reel and the tube. When a forward current flows through the coil unit, the core is attracted by the magnet so as to move to an upper limit position, where the hole is open, thereby permitting the water flow through the hole. When the core is disposed at the upper limit position and when a reverse current flows through the coil unit, a magnetic repulsion force is created between the magnet and the core, thereby returning the core to the lower limit position with assistance from the spring.
