  • Patent number: 8667987
    Abstract: A flow path switching valve is disclosed that can be operated remotely simply by turning flow on and off. A mid portion of the body has at least one passage therein leading from a central axial bore to one or more external ports each having a tractor nozzle. The valve outlet connects the axial bore to a cleaning nozzle. A poppet member is received in the central axial bore. In a first position, the poppet member directs fluid flow through the outlet to the cleaning nozzle connected to the outlet. The poppet member, when in a second position, closes the central axial bore through the outlet end of the valve body and permits fluid flow through the tractor nozzles. Selection of the different flow paths is made by simply reducing flow through the valve below a predetermined fluid flow threshold and then increasing the flow rate above the threshold.

  • Patent number: 8667978
    Abstract: A methods and system detecting water system leaks provides detecting of water leakage having very low flows. Very low flow leaks are detected by detecting drops in a building water system pressure when the water supply source is disabled. The water system is disabled by an electrically controllable valve, which may be turned off in response to a motion detector that detects that no human activity is present in the building. The rate of pressure drop is used to determine the magnitude of the leak, and multiple thresholds can be used to detect slow leaks versus more serious leaks. A humidity detector may also be incorporated in the system to detect abnormal humidity conditions and shut the electrically controllable valve in response. Appliance current consumption can be detected and used to override motion-sensor based shut-off of the valve, so that water-consuming appliances can continue to operate.

  • Patent number: 8573244
    Abstract: A relief valve assembly to relieve overpressure of a pressurized fluid. In accordance with some embodiments, the assembly comprises a housing with an inlet and an outlet to form a conduit for a pressurized fluid. A normally closed valve member is axially displaceable within the housing to engage a valve seat to prevent a flow of the pressurized fluid along the conduit. A biasing member applies a bias force to the valve member to retain the valve member against the valve seat. A piston within the valve member contactingly engages the pressurized fluid. A mechanically collapsible member resists axial movement of the piston responsive to said contacting engagement of the pressurized fluid. The piston and collapsible member decouple the bias force supplied by the biasing spring member upon the valve member from a force upon the valve member applied by the pressurized fluid, thereby maintaining a bubble-tight seal.

  • Publication number: 20120085424
    Abstract: A method and a fuel tank system for adjusting a pressure in a fuel tank are described. Evaporated fuel tank escapes from the fuel tank under overpressure with respect to the ambient and is transferred to a temporary storage for at least one substance of the evaporated fuel. A venting means, through which the evaporated fuel escapes, is controlled by at least one parameter different from a pressure or at least one information provided in form of data. The pressure in the fuel tank can thereby be more variably adjusted.

  • Publication number: 20110041938
    Abstract: A fuel return block has a body with a coaxial inlet and outlet generally perpendicular to the body, a return port communicating with an inlet, and a vent generally parallel to the inlet and the outlet while communicating with the return port. The inlet and the outlet have external threading for connection to a fuel tank and to a fuel line. A common space between the inlet, the outlet, the return port, and the vent has a particular geometry conducive to ventilation of the fuel return block but not allowing escape of fuel through the vent. The inlet secures to a manufacturer's fitting upon the fuel tank so no second opening is required. The fuel return block equalizes pressures of the inlet, the outlet, and the return port preventing tank damage and interruptions to fuel delivery from negative pressure.

  • Publication number: 20100170572
    Abstract: The present invention generally relates to devices and methods for affecting the flow rate of fluid using pressure. The invention generally provides for controlled application of pressure to flowing fluids to control pressure and flow rates of those fluids, independent of location of the fluids relative to various devices. For example, in a series of devices, each connected to another via a conduit, pressure control units can be provided between devices to raise or lower pressure and/or flow rate of fluid flowing from one device to the next. In this way, a series of interconnected devices can be arranged such that inlet fluid pressure or flow rate of any individual device can be set independently of every other device.

  • Patent number: 7735749
    Abstract: A fountain (50) comprises a supply of water under pressure, a primary fluidic diverter (10) having an input (12) for said supply, and first and second outputs (16a, b) diverging from said input. Two control ports (20a, b) are provided with control flow to direct input flow to one or other of the two outputs that lead to the two inputs of a vortex amplifier (40). This comprises a vortex chamber (54), a radial port (50), a vortex inducing port (60) and an axial output port (58). One (16a) of the diverter outputs is connected to the vortex inducing port, the other (16b) to the radial port, so that supply to said axial output port is modulated by formation of a vortex in the chamber when flow is to the vortex inducing port. The axial port leads to a nozzle whereby a vortex spray or axial jet is produced, depending on which diverter output (16a, b) is active. A wind detector (100) has a vertical jet (102) and a catcher (104) which fails to catch water from the jet in high wind conditions.
