Abstract: Embodiments provide a fitting that is integrated into the valve body of a ball valve during the manufacture of the valve body. The fitting and a cartridge may be overmolded to create the valve body. The mold may apply a pressure onto the fitting during the molding process. The fitting may transfer the pressure of the mold onto the cartridge. The fitting may transfer a sufficient amount of force to seal valve seats of the ball valve.
Abstract: A hand-held dual flow dilution dispenser for precisely controlling the flow rate of water therethrough and for precisely injecting a liquid chemical into the water passing through the apparatus. The dispenser includes a water spool valve and a chemical spool valve with the spool valves being rotated between first and second positions. A handle is operatively connected to the first spool valve for rotating the first spool valve between the first and second positions. A linkage interconnects the handle and the second spool valve whereby rotational movement of the handle simultaneously causes rotation of the first spool valve and the second spool valve.

Abstract: A channel forming member is attached to a filler neck on a nozzle insertion side where a fueling nozzle is to be inserted. The channel forming member includes a barrier section that forms an insertion flow path section for the fueling nozzle in the fuel flow path on the nozzle insertion side, while forming an annular channel surrounding the insertion flow path section so as to separate the channel from the insertion flow path section. The channel forming member further includes the following provided to the barrier section: an atmosphere communication hole for making the channel communicate with the atmosphere; a flow path communication hole for making the channel communicate with an insertion end flow path section downstream from the insertion flow path section; and a valve mechanism that prevents passage of the atmosphere through the channel in a fueling period. This contributes to reduction in introduction of the atmosphere into the fuel flow path through the channel in a fueling period.
Abstract: A valve assembly includes a valve body having at least a first bore and a second bore, a flow passage connecting the first bore to the second bore, a plurality of ports opening to each bore respectively, the first bore being upstream of the second bore. First and second spools are disposed in the first and second bores, respectively, for controlling the flow of fluid to and from the respective ports. A check valve is disposed in the flow passage and configured to prevent fluid flow from the second spool towards the first spool through the flow passage while allowing fluid flow from one of the ports in the first bore towards the second spool through the flow passage.

Abstract: Methods and systems are provided for identifying misfueling in a vehicle fuel tank when an incorrect fuel type is provided. In one example, a method may include routing fuel vapors from a vehicle fuel tank to a fuel vapor storage canister and monitoring a temperature profile of a fuel system canister during a refueling operation, and when an actual temperature profile is below an expected temperature profile, misfueling is identified. Further, responsive to an indication of misfueling, further addition of fuel is disabled during the refueling event.
Abstract: A water leak detection assembly for sensing and stopping a water leak in a building includes a screw that is inserted into a wall having the screw being positioned proximate a pipe for a plumbing fixture in a building. A sensing unit is provided and the sensing unit is positionable in the screw having the sensing unit being aligned with the pipe. The sensing unit senses moisture thereby facilitating the sensing unit to detect water leaking from the pipe. A shut off unit is provided and the shut off unit is fluidly coupled to a water supply pipe for the building and the shut off unit is in electrical communication with the sensing unit. The shut off unit turns off the water supply pipe when the sensing unit senses water thereby stopping the potential water leak.
Abstract: A fluid pulse dampener with automatic pressure-compensation is provided. A system of chambers and channels in the dampener creates an internal feedback mechanism that increases or decreases a compensating pressure on the membrane in response to increases or decreases in the pressure of a fluid moving past the other side of the membrane. Variations of the pulse dampener allow for the input and/or output of gas flow is be restricted or increased as may be desired.
Abstract: A pipeline control unit that joins pipeline conduits and has a housing with an interior compartment for receiving a gate. A valve servicing assembly or pressure plates can be installed onto the housing to form a fluid tight structure to allow removal and replacement of a retained gate without depressurizing a pipeline system. Strongbacks attached to the housing can compress lateral walls of the housing to secure a gate in the interior compartment, and removal of such compression allows removal of the gate while the pipeline is pressurized.
Abstract: A manifold having a first side, a second side, a first channel extending from the first side to the second side, and a second channel extending from the first side to the second side is disclosed. The first channel and the second channel each define a linear longitudinal axis. In one embodiment, the first channel longitudinal axis and the second channel longitudinal axis are oblique to the first side and the second side of the manifold. The manifold of the present disclosure provides channels that can be easily cleaned and allow for an increased flow performance.
Abstract: A device and method that relates to a swivel arrangement for a carousel filler arrangement having a rotating tank and a product pipe for transporting product into the rotating tank are disclosed. The swivel arrangement may include a tank connecting part, a pipe connecting part, a first opening for receiving a gaseous media, and a second opening for ejecting the gaseous media. A first channel may be partly defined by a protruding portion of the pipe connecting part and an outer wall of the product pipe, and a second channel may be partly defined by the protruding portion and a protruding portion of the tank connecting part.
