  • Publication number: 20110012037
    Abstract: Providing a noise reducing water valve, intended to be installed inside the bottom piece of an existing flush valve installed in a toilet as a retrofit or built-in inside a new flush valve, in order to reduce and control the unnecessary and excessive water flow present in a noisy toilet. High levels of noise are found on regular toilets when excessive water flow and water pressure are used during the flushing of the units. By limiting the amount of water that enters the toilet bowl through the flush valve, while still allowing sufficient water for a good flush of the unit, we will control the noise generated by the run of the water from the toilet tank to the toilet drain. The noise reducing valve will have a key component which is a flow disc reducer piece that will come in different opening sizes, to be inserted inside the said valve, in order to find the most suitable flush water flow for fine tuning each toilet.

  • Patent number: 7565916
    Abstract: The pneumatic oscillating valve includes a housing defining an internal chamber, an inlet passageway, and an outlet passageway. An annular seat extends into the internal chamber. A diaphragm is disposed in the internal chamber. The diaphragm seats against the annular seat and separates the inlet passageway from the outlet passageway. A spring engages the diaphragm to seat the diaphragm against the annular seat. As fluid is admitted to the inlet passageway, pressure increases in the inlet passageway until sufficient pressure is present to overcome the spring and unseat the diaphragm. The inlet passageway is more restrictive to fluid flow than the outlet passageway such that fluid is exhausted more quickly from the outlet passageway than can pass through the inlet passageway allowing pressure in the inlet passageway to reduce to a point less than the spring force of the spring thereby allowing the diaphragm to reseat on the seat.

    Abstract: A detachable fluid coupling for connecting an inkjet printhead with an ink supply, the detachable coupling having a fixed valve member defining a valve seat, a sealing collar (146) for sealing engagement with the valve seat (148), a resilient sleeve (126) having one annular end fixed relative to the fixed valve member (128), and the other annular end engaging the sealing collar to bias it into sealing engagement with the valve seat. The coupling also having a conduit opening (150) that is movable relative to the fixed valve member for engaging the sealing collar (146) to unseal it from the valve seat. Unsealing the sealing collar from the valve seat compresses the resilient sleeve (126) such that an intermediate section of the sleeve displaces outwardly relative to the annular ends. With a resilient sleeve that buckles or folds outwardly, the diameter of the coupling is smaller that the conventional couplings that use an annular resilient element that biases the valve shut remaining residual tension.

  • Patent number: 7426938
    Abstract: A choke valve having flow trim components, namely a tubular cage and a flow collar or plug, and related components, designed and arranged for reduced fracturing. The invention includes a protective tubular sleeve, or insert cartridge in which the side ports are located to overlap with the intersection of axes of the inlet and outlet bores, but to avoid direct impingement of fluid along the axis of the inlet bore. In the cage, at least a pair of main flow ports are located to overlap with the intersection of the axes of the inlet and outlet bores, and are aligned with the side ports of the tubular sleeve or cartridge to communicate directly with the side ports. In this manner fluid may enter the choke valve through the inlet bore and pass through the main flow ports at reduced pressure and continue out through the outlet bore, without direct impingement on the side wall of the flow trim components.

  • Publication number: 20080173835
    Abstract: A regulator on a valve mechanism for controlled release of pressurized gas from a container. The valve mechanism includes a valve body mounted within a top of the container, a reciprocating core, a return spring, and a resilient sealing gasket. A tubular stem extends upwardly from the core and through an opening in the top of the container. The gasket maintains an airtight seal between a gas flow passage in the valve body and the stem, thereby preventing release of the gas from the container while the spring holds the valve body in a normally closed position in sealed engagement with the gasket. Forced movement of the stem, against the spring, allows passage of the pressurized gas into an axial bore of the stem for release out from a nozzle tip of a cap fitted to the stem. A flow regulator is fitted to the lower end of the valve body and provides a pinhole opening sized according to the desired gas release flow rate.

  • Patent number: 7219690
    Abstract: A two-stage fluid pressure control valve has five components. An inlet socket with separate fluid flow orifices sealably engages an outlet socket which also has separate fluid flow orifices. A pressure check piston having a fluid flow orifice along its longitudinal central axis slidably engages the inlet socket and the outlet socket. A spring located along the central axis of the outlet socket biases the pressure check piston in an open position, allowing fluid to flow through all orifices. Fluid flow through the control valve may impact the pressure check piston to overcome the spring force, moving the pressure check piston to a closed position, whereby fluid flows only through the orifice in the pressure check piston.
