The flow-through mount may include a plurality of bypass openings positioned in the fluid flow path and configured to divert a portion of the fuel flow through a hose to the remote fuel vent.

Abstract: A fuel tank for vehicles has a filler tube and a filling level limiting device, with the filler tube comprising, in the interior of the fuel tank, a closing device which interacts with an actuating device which is composed of: a) a frame which is fastened in the interior of the fuel tank and which has a force store which actuates the closing device; b) a locking arrangement which holds the force store in the stressed state; c) a release mechanism which is operatively connected to a float; and d) a stressing mechanism for stressing the force store. The actuating device ensures that a flap closes precisely when a nominal filling level is reached, and does not open again even under intense fluctuation of the liquid level.

Abstract: A fuel storage tank includes an overfill protection device for shutting off the flow of fuel into the tank via a fuel fill tube when the contents of the tank reach an intended maximum fill level. The overfill protection device includes a butterfly valve located within the fuel fill tube and a float, slidably mounted outside the fuel fill tube and operatively linked to the butterfly valve. The float rotates the butterfly valve towards the closed position in response to an increasing fuel level in the tank.

Abstract: It is of the type comprising a body of vertical axis and arranged at least partially in the tank, an interior partition being mounted in the body and delimiting a passageway for the liquid and a chamber to house a float, a valve mounted above the passageway and the float chamber, the valve being capable of moving between an open position and a closed position, and a valve seat, the said float being moved vertically by the rise of the liquid in the tank and acting on the valve via operating means comprising an operating rod, the lower end of which is secured to the float, the other end of the operating rod comprises a ball moving in a groove formed in part of the valve.

Abstract: In an arrangement for limiting the fill level in a fuel tank having a filler neck with a tank inlet end, a valve flap is pivotally supported in the inlet end such that, in an open position, the valve flap is pivoted toward the fuel flow entering the tank during refueling and is connected, by way of a crank arm and a coupling rod to a float which is disposed in an essentially vertical guide tube. The coupling rod extends through the float and has spaced top and bottom stops providing for lost motion coupling between the float and the coupling rod whose weight is sufficient to keep the valve flap in an open position. When the fuel in the tank lifts the float and, after the float engages the top stop, lifts the coupling rod, closing movement of the valve flap is initiated which is then fully closed by the inflowing fuel utilizing the lost motion distance between the float and the bottom stop of the coupling rod.

Abstract: A snap-action flow interrupt device for terminating flow into a cryogenic storage container utilizes the momentum of the incoming liquid spray as a means of maintaining a float in a submerged position until the proper liquid level is attained. The incoming spray of liquid exerts a downward impact force on a surface of the float. The rising liquid level exerts an upward and increasing buoyant force on the float. When the rising liquid in the tank disrupts the spray, the buoyant force snaps the float upwards to interrupt the flow of liquid. The abrupt motion of the float generates a pressure spike and flow reduction, either of which may be easily detected by automatic fill termination devices or by a human operator.

Abstract: A filling regulator for a liquid storage tank of the type according to which a float is displaced vertically in the float chamber provided in the body of the regulator. The regulator includes a deflector slanted over the inner wall of the body and installed above the gate at a far enough distance above the float chamber to allow the gate to be positioned in the full-open position. The deflector includes slanted, spaced-apart blades which are joined at their lower ends by a protective base.

Abstract: A two-stage float actuated shut-off valve for use in underground fuel storage tanks utilizes a drop tube coaxially mounted within the storage tank fill pipe. Fuel flowing into the tank is passed through the drop tube which projects downwardly into the interior of the tank to a valve housing located at the lower end of the drop tube. Floats slidably mounted in a recessed area in the housing outside of the drop tube within the tank independently operate pivoted valve doors to a closed position within the valve housing, a lower float closing one valve door to block a major portion of incoming fuel flow passage when the level of fuel in the storage tank reaches a predetermined first level and a second upper float causing the secondary valve door to overlap an aperture in the main valve door to almost completely close the flow of fuel to the tank.

Abstract: In a fuel inlet device for a fuel tank, a flap valve is provided at an end of a fuel filler tube opening into the fuel tank, and a float which rises with a rise in a surface level of the fuel in the tank closes this flap valve when the fuel surface level has reached a prescribed level. Thus, when the surface level of the fuel in the fuel tank has reached a prescribed level, the flap valve linked with the float is closed, and prevents any more fuel from being filled into the fuel tank because the filling nozzle detects this rise in the surface level of the fuel in the filler tube, and stops filling any more fuel into the tank. Therefore, it is possible to connect the breather tube in the fuel tank directly with a canister device without the intervention of a relief valve, and the internal pressure of the fuel tank can be maintained substantially no higher than the atmospheric pressure. Thus, the release of fuel vapor from the filler cap can be avoided.

Abstract: A float type liquid level meter is provided having an enhanced resistance against vibration transmitted from outside of the float type liquid level meter. The inventor obtained a finding that an external vibration is amplified with a connecting lever which is composing a part of the float type liquid level meter and a fluctuation of an output signal of the float type liquid level meter is proportional to the vibration of the connecting lever. An enhanced resistance against vibration is achieved by providing a connecting lever having a structure which prevents the connecting lever from generating vibration of a low order mode.

Abstract: A filter apparatus is used to filter tap water and to automatically fill two containers. This apparatus includes a filter subassembly, a housing subassembly, a water control subassembly, and first and second containers. The water control subassembly includes a center see-saw chute receiving filtered water from a supply line from the filter subassembly, and includes a left pivoted chute and a right pivoted chute, each receiving a selectively directed water stream from the center chute. Each pivoted chute has a float at one end thereof, in contact with the water in its respective container when about full. An upward force from its container water pivots each left and right chute, when the container is about full, causing the respective water stream to be redirected in the opposite direction along its chute to a reservoir and drain line.

Abstract: A float chamber located in generally parallel, laterally spaced relationship to the main liquid flow passageway contains superimposed floats that move along a substantially linear path of travel. The floats cooperate with other control components to effect closure of a main valve assembly when the liquid level adjacent the mechanism reaches a preselected first elevation, and to close a bleed valve assembly when the liquid level reaches a second, higher elevation. The main valve assembly includes a movable plate valve that is spring biased toward an open position and that is biased toward a closed position by the force of liquid adjacent thereto and upstream therefrom. A latch and associated catch prevent movement of the valve plate to its closed position until such time as the liquid level reaches the first elevation.

Abstract: An automatic shut-off nozzle has liquid flow through its vapor return means stopped in response to movement of an actuator by a flexible diaphragm when liquid has filled the vapor line sufficiently to move a float into engagement with the diaphragm. The actuator produces a signal to cause stopping of liquid flow through the nozzle. In another embodiment, a flexible diaphragm is positioned to block vapor flow through the vapor return means when a predetermined quantity of liquid is collected by the diaphragm. The blocking of the vapor return means creates an increased pressure, which can be sensed by a pressure transducer, for example, with the pressure transducer producing a signal to stop liquid flow through the nozzle. The automatic shut-off nozzle also stops flow in response to the tank being filled to a predetermined level with liquid or to the pressure in the tank exceeding a predetermined pressure.
