  • Rocker type diaphragm valve
    Patent number: 8141585
    Abstract: A rocker type diaphragm valve is disclosed. The diaphragm (428) in the diaphragm valve is asymmetric and the stroke of the diaphragm is offset from the center of the diaphragm. The two sealing surfaces (318, 320) that the diaphragm acts against form two planes that make an angle with respect to ones another. The diaphragm (428) may be fabricated in only one piece. The diaphragm (428) may also be made from a resilient material and shaped in such a way as to create a spring force holding the diaphragm into a default position in the valve.

  • VALVE WITH A SPRINGY DIAPHRAGM
    Publication number: 20100001223
    Abstract: A diaphragm membrane (212) is disclosed that has a shape that spring loads a diaphragm during assembly to provide a default position for the diaphragm. The diaphragm membrane (212) is made from a resilient material. The diaphragm is spring loaded during assembly to provide a force that returns the diaphragm to the default position.

  • Fluid Control Device And Method For The Production Thereof
    Publication number: 20090211238
    Abstract: The invention relates to a fluid control device comprising at least one fluid actuator, such as pistons, membranes, disks, base bodies comprising combinations thereof or similar and at least one cover element. Control/supply channels, which are fluidcally connected to fluid channels which are arranged in the base body, are arranged in the base body and/or in the cover element. The control/supply channels are defined between the base body and the at least one cover element by means of welding joints which are produced by laser welding.
