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.

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).

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.

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.

Abstract: An improved control valve for a reverse osmosis (RO) water purification system for supplying relatively pure water for on-demand dispensing, wherein the improved control valve positively terminates pure water production and brine outflow to a waste or drain when a pure water reservoir reaches a substantially filled condition. The control valve responds to a predetermined pressure differential between a tap or feed water inflow and produced pure water to close a pure water outflow line when the pure water reservoir reaches a substantially filled condition, thereby positively preventing further production of pure water. Shortly thereafter, the control valve closes a brine outflow line thereby positively preventing further water flow through the system until at least a predetermined volume of the reservoir-stored pure water is dispensed. When this occurs, the control valve re-opens in sequence the brine outflow and the pure water outflow lines.
