  • Patent number: 9790669
    Abstract: A water-saving device for a faucet has a main body. A flow-controlling member and a movable flow-blocking member are mounted in the main body. The main body has multiple receiving holes that receive respectively multiple positioning balls. A driving member movably receives an outer surface of the main body. When the faucet is open, the flow-controlling member and the flow-blocking member facilitate a water flow that is adjustable and stable. A user pulls the driving member downwards for increasing the water flow as required. The positioning balls are mounted in the driving member. The flow-blocking member that is pressed by the water flow moves downwards. When the faucet is closed, the flow-blocking member restores to an original position, thereby automatically adjusting the faucet to a minimum water flow for next use and economizes the water usage.

  • Patent number: 8656948
    Abstract: A wide variety of machines have moveable members that are operated by an hydraulic actuator. For example, an internal combustion engine has a camshaft which is mechanically coupled to rotate with the crankshaft and which opens and closes cylinder intake and exhaust valves. Traditionally the camshaft timing was fixed at a setting that produced the best operation for all engine operating conditions. However, it has been recognized that engine performance can be improved if the valve timing varies as a function of engine speed, engine load, and other factors. Thus a hydraulic actuator is being used on some engines to vary the coupling relationship of the camshaft to the crankshaft. A solenoid operated valve controls the application of pressurized fluid to operate the hydraulic actuator.

With the stopper installed within the outlet and the extending section and the abutment members therewith assembled to the stopper thereby sealing the passage therein, fluid within the container may be extracted via the fluid conduit as air exterior to the container flows therein via the air conduct to displace the fluid being extracted from the container.

  • Patent number: 8215339
    Abstract: A vapor barrier for sealing an interior of a building from an insulation cavity defined by framing members of the building includes a flexible and substantially impermeable sheet having apertures to allow air to exit the insulation cavity during filling of the insulation cavity with loose fill insulation. The vapor barrier also includes one-way valves mounted across the apertures. The valves are configured to allow air flow out of the insulation cavity and into the building interior through the apertures and to prevent air flow and moisture diffusion from the building interior into the insulation cavity.

  • Patent number: 8186378
    Abstract: An electrohydraulic valve has a valve body with a longitudinal bore and a cylindrical exterior surface. An annular recess extends around the cylindrical exterior surface and the first port extends from the recess to the bore. A filter is formed by a plate that has a plurality of perforations and which is wrapped around valve body in the recess. The plate has a first end section at which a first tab is created and a second end section overlapping the first end section with a slot through which the first tab extends to secure the first and second end sections together. A spool is slideable into different positions within the bore of the valve body to selectively connect and disconnect the first port and a second. An actuator is operably coupled to move the spool into different positions within the bore.

  • Patent number: 8172091
    Abstract: The present invention relates to a connecting element for hydraulic circuits. The device comprises a body provided with one channel having an inlet section and an outlet section, the channel being connectable with a fluid supply line, said body being further provided with an aperture which opens, to the outside, into a seat located in the channel. The devices also comprises a filter element insertable in a removable manner into the seat, through the aperture, in order to intercept the fluid in the channel. Advantageously the filter element is defined by at least two portions, coupled with angled or radiused joints to define an internal volume, one portion having a different geometry from the other.

  • Patent number: 8171955
    Abstract: A relief vent assembly for a fuel storage tank includes a vent body defining a chamber to provide a substantially axially smooth and unencumbered path of flow for pressurized fluid to vent out from the tank. Such a path of flow allows the pressurized fluid to remain laminar throughout approximately the entire path through the chamber, maintaining a high flow rate. The vent assembly includes a crossbar that supports the rod of a lid that covers a distal margin of the vent body. The crossbar is disposed substantially at the distal margin of the vent body to prevent any premature turbulent flow of the pressurized fluid, which would slow the flow rate. A widening tapered bore of the chamber increases the flow area and serves to offset the area occupied by the crossbar.

  • Patent number: 8141572
    Abstract: An isolation valve system includes a main body (32), an actuator body (34) and a sealing membrane (307) arranged at a high pressure portion (36) of the isolation valve system. The sealing membrane mechanically attaches the actuator body to the main body. The sealing membrane further seals the high pressure portion from a low pressure portion (38). A burst plug (315) is arranged against the main body and supports the actuator body. An activation arrangement (50) is arranged for allowing an at least partial displacement of the burst plug, typically causing a phase transition. The sealing membrane is dimensioned to break when the actuator body is moved due to the displacement of the burst plug. The isolation valve system includes preferably a stack (30) of substrates (301-304) being bonded together. The substrates have micromechanical structures, which form at least the actuator body and the sealing membrane.

  • Patent number: 8127790
    Abstract: An hydraulic valve has a body with an exterior surface, a longitudinal bore, and first and second fluid ports in communication with the bore wherein the first fluid port opens through the exterior surface. A band is wrapped in first and second layers around the exterior surface which layers extend over the opening of the first fluid port. The first layer has a plurality of apertures there through and overlaying the opening to provide a filter. The second layer has a flap that flexes in response to pressure to open and close the plurality of apertures thereby acting as a check valve. An actuator slides a spool within the bore thereby selectively connecting and disconnecting the first and second fluid ports.
