  • Patent number: 8714201
    Abstract: A water-saving device structure is provided. When the pressure of an entry water is high, a water-barrier sheet body is pressed to cause a downwardly-moved elastic stopping portion to block a water-inflow opening of a water-outflow seat body, so that the water flow is conducted to a water-outflow opening through a water-conducting opening of the water-barrier sheet body. When the pressure of the entry water is low, the entry water is conducted to the water-outflow opening via one path traveling from the water-conducting opening of the water-bather sheet body to the water-outflow opening of the water-outflow seat body and the other path traveling along the clearances of stopping wall portions of the water-outflow seat body, a water-storage circular slot portion, the water-inflow openings of the water-outflow seat body and the water-outflow opening of the water-outflow seat body. Therefore, the outflow water with steady flow rate can be obtained.

  • Patent number: 8485220
    Abstract: An automatic flow regulator valve designed to regulate water pressure from a liquid source outlet in the event of pressure surges and/or fluctuations. In an “open” position, the predetermined water flow pressures are not sufficient to overcome a spring force of a spring. Therefore, a sealing plate is maintained separated from a step by the spring force, thus allowing water to flow around the outmost perimeter edge of sealing plate. In operation under water flow pressure surges and/or fluctuations, the automatic flow regulator valve is “closed”. In the “closed” position, the water flow pressure surges and/or fluctuation pressures are sufficient to overcome the spring force of spring. Therefore, the sealing plate is biased against the step and the water does not flow around the outmost perimeter edge of sealing plate since sealing plate is biased against the step.

  • Patent number: 8251066
    Abstract: A pressure sensitive valve device for use with respiratory equipment of the type that produces a pressurized flow of breathing gas. The valve device combines the exhalation and entrainment functions in one valve with a single air path. The valve device provides an exhaust valve function during normal operation and provides a less restricted access to the ambient atmosphere in the event of respiratory equipment malfunction. The valve device includes a valve element that moves between at least two positions. During normal operation, when the pressure generating system is generating a flow of gas, the valve element is in a “closed” or “exhaust valve” position. When in the exhaust valve position, the gas flow to the atmosphere is restricted without being completely blocked off. When the flow of gas is decreased or interrupted, the valve element moves to the “entrainment valve” or “open” position that allows a greater, i.e., less restricted flow, of gas between the user and the ambient atmosphere.

  • Patent number: 8002040
    Abstract: A technique enables control over flow in a wellbore with a flow control system. The flow control system combines a flow reduction mechanism with a flow control device, such as a valve. The flow reduction mechanism comprises a closure member which can be selectively moved between an unactuated and actuated position, allowing relatively greater flow through the flow control device in the unactuated position. The flow reduction mechanism actuates prior to or in conjunction with the flow control device to reduce flow and thus reduce the loading forces that would otherwise act against the flow control mechanism upon closure of the flow control device.
