  • Patent number: 9016302
    Abstract: A cold/hot water balance valve prevents burning or scalding of the users. The valve is accommodated in the holding space preset into a dual-temperature ceramic valve. The balance valve mainly includes a hot water stop flange, protruded from a first lateral end wall, and meshed with a first end of a moveable spool to block a hot water stream when the first end shifts towards the first lateral end wall. A minimum cold water retaining portion is protruded from the second lateral end wall. When the second end of the moveable spool shifts towards the second lateral end wall, the minimum cold water retaining portion will be abutted onto the second end of the moveable spool, such that a minimum flow gap is reserved between the second end and the second lateral end wall, allowing for constant flow of water stream through the cold water slot of the moveable spool.

  • Patent number: 8985132
    Abstract: A balance valve is provided with an asymmetric structure. When the dual-temperature ceramic valve is switched to cold water supply modes, and the hot water line is blocked to make a moveable spool abutted towards a first lateral end wall of a holding space, a cold water channel can thus be formed between the cold water opening of a fixed valve pipe and a second end of the moveable spool with the setting of the asymmetric structure. Hence, cold water supply can maintained. When the hot water line is blocked, the cold water supply function of the balance valve of the present invention could still be maintained for improved convenience and applicability.

  • Patent number: 8869816
    Abstract: A mixed water control valve for a faucet includes a valve housing, a control unit, and a balance unit. The valve housing has a mounting seat which has a receiving chamber and two water inlet holes. The balance unit includes a fixed sleeve secured in the receiving chamber, a pressure regulating sleeve movably mounted in the fixed sleeve, a balance baffle mounted in the pressure regulating sleeve, and two elastic members each mounted in the pressure regulating sleeve and each biased between the balance baffle and the mounting seat. Thus, the balance baffle is compressed between the elastic members which provide a buffering force to counteract a larger pressure applied on the balance baffle, so that the pressure regulating sleeve is moved smoothly and stably without producing resonant noise in the faucet.

  • Patent number: 8826659
    Abstract: PCV systems are well known in the art and commonly used in turbocharged engines. The ejector creates a pressure drop for additional pull of PCV gas under boosted conditions of the turbocharger engine. The ejector typically includes a first inlet and a second inlet and a sole outlet. The first inlet pulls air from the compressor of the PCV system. The second inlet pulls air from the cyclone separator of the PCV system. Air exiting the ejector is exited to the intake manifold. However, when the turbocharger of the system is off, fresh air can leak in from the inlet from the oil separator thereby preventing the ventilation of blowby. The unwanted air reduces the efficiency of the turbocharger system. Accordingly, an ejector preventing unwanted fresh air flow is needed in the art.

  • Patent number: 8746269
    Abstract: The present invention relates to a method and apparatus for controlling a gas flow through a conjunction between one or more incoming streams and one or more outgoing streams through a conjunction. The method uses a biased mass flow imbalance value obtained by comparing the aggregate of incoming mass flow measurement value(s) with the aggregate of outgoing mass flow measurement value(s) and adding a bias component to provide the biased mass flow imbalance value. The flow of at least one of the incoming and outgoing streams (12, 14, 16, 18, 20) is adjusted to move the biased mass flow imbalance value towards zero. In addition, a conjunction pressure measurement (PC) is provided, which is used to adjust the bias component in response to a change in the conjunction pressure measurement (PC) relative to a pressure set point (PSP), to mitigate the change in the conjunction pressure measurement (PC) relative to the pressure set point (PSP).

  • Patent number: 8740098
    Abstract: The initially cold water streams of a household hot water plumbing circuit are accumulated in a storage container to be thereafter drained off with the cold water stream, at various flow restricted levels, thereby conserving water use. This accumulate may be adjustably admixed into the waste products of a household drinking water purification system, thereby diluting it to acceptable levels that may be useful for washing and the like. Additionally, and/or alternatively, the fresh water stream may be admixed into the water purification waste water stream. Each of these water conserving functions is conformed to be combined in a stepwise manner, thereby accommodating budgetary and use growth constraints.

  • Publication number: 20140048141
    Abstract: Flow distribution networks that supply process gas to two or more stations in a multi-station deposition chamber. Each flow distribution network includes an inlet and flow distribution lines for carrying process gas to the stations. The flow distribution lines include a branch point downstream from the inlet and two or more branches downstream from the branch point. Each branch supplies a station. The flow distribution network also includes highly variable flow elements in each branch. Restrictive components are placed downstream from the variable control elements in each branch. These restrictive components are nominally identical and designed to shift the bulk of the pressure drop away from the variable flow components to improve flow balancing while not unduly increasing inlet pressure. In some cases, the load shifting allows the more variable flow components to operate in the unchoked flow regime.
