20080237523 | Valve with Outlet Duct - A valve has a first duct and a second duct at right angles to the first duct. The first duct opens into a connecting portion of the second duct, defining an intersection that forms a seat for a valve disk that slides in the connecting portion in a direction at right angles to the seat between a closed position and an open position. The connecting portion has two flat walls facing one another and connected by an end wall. The first duct opens onto one of the flat walls. The end wall partially surrounds the valve disk parallel to the a direction of sliding at a distance from an edge of the valve disk that is such that, for the open position, the end wall defines with the edge of the valve disk and the seat a passage. | 10-02-2008 |
20080277614 | Quantum fluid transfer system - A miniature quantum fluid transfer system configured to regulate the flow rate of a fluid by allowing passage of very small, discrete increments of fluid through the valve including a valve body having at least one inlet to receive fluid and at least one outlet to release fluid. The quantum fluid transfer system includes a valve rod movably disposed in a first chamber in the valve body. The valve rod has a plurality of fluid passages spaced longitudinally along the valve rod, and the valve rod is movable to align each fluid passage with an inlet or outlet port in the first chamber to allow fluid to flow through selected inlet or outlet ports corresponding to selected fluid passages. The quantum fluid transfer system has a plug movably disposed in a second chamber in the valve body. The plug is movable between a first end and a second end of the second chamber, and moves toward the first or second end when a volume of fluid enters the second chamber from the first chamber at the other of the first or second end. The plug pushes a corresponding volume of fluid out of the second chamber at the end opposite the end the fluid entered. | 11-13-2008 |

20120091379 | Water Conservation Shower Valve - A pushbutton device that will stop the flow of water to the showerhead by closing a valve after the hot and cold water is mixed to the desired temperature and water force. This button will operate a simple “push-to-open/push-to-close” valve, which will interrupt the water flow to the showerhead. The button will be clearly marked PAUSE, and will be visible to the user. While the button will highly visible to the user, it will be mounted in low relief to the wall, with smooth and rounded surface and edges, and will not pose a danger to the user in the event of a slip in the shower. This invention is meant to enable the user to instantly change the amount of water used for showering, by allowing the user to immediately stop the water flow and re-start the flow, without the need to re-adjust the water temperature and water force. Once the temperature is set and the water force is achieved the user will able to stop and start the water without having to reset. The objective is to enable the user to save significant amounts of both water and the energy needed to heat the water to the desired showering temperature, without having to spend any time, at all, thinking about it. | 04-19-2012 |
