Abstract: A fuel dispensing nozzle comprises a nozzle body defining a dispensing path extending between a distal inlet and a proximal outlet and configured to dispense fuel. A fuel flow valve is disposed in the nozzle body between the distal inlet and the proximal outlet. An actuation assembly movable to open the fuel flow valve is also provided. The nozzle also includes a shut-off mechanism operatively connected to the actuation assembly. A hand lever is pivotally connected with respect to the nozzle body, the hand lever being operatively connected to the actuation assembly so as to cause opening of the fuel flow valve when the hand lever is pivoted in a valve opening direction. The hand lever has a grasping portion extending between a proximal location nearer the proximal outlet and a distal location. The nozzle according to this aspect further includes a hold open mechanism including a trigger disposed at the proximal location of the hand lever.

Abstract: A vehicle fueling control system according to an exemplary aspect of the present disclosure includes, among other things, a fuel inlet conduit configured to receive a fuel dispensing nozzle, and a blocking assembly. The blocking assembly is configured to move back and forth between a fill blocking position that blocks airflow through a port of the fuel dispensing nozzle and a fill permitting position that permits airflow through the port of the fuel dispensing nozzle.

Abstract: A non-pressure valve is provided, and includes a tubular housing having an inlet and an outlet. The tubular housing forms a fluid flow path. The non-pressure valve also includes a sliding sleeve coupled with the outlet, a spring disposed between the sliding sleeve and the tubular housing, and a flow-through mount disposed within the tubular housing adjacent the sliding sleeve. The flow-through mount is coupled with a bulb. The bulb is configured to engage the sliding sleeve and impede the flow of fuel. The non-pressure valve also includes a hose fluidly coupling the non-pressure valve with a remote fuel vent. 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 refueling system including a nozzle configured to dispense fuel through a fuel path thereof into a vehicle tank. The nozzle includes a vapor path configured such that vapor recovered from the vehicle tank during refueling is passable therethrough. The system further includes a sensing valve disposed in the vapor path, wherein the sensing valve is configured to generally block the associated part of the vapor path when a sufficient vacuum from the vehicle tank is applied to the sensing valve during refueling. The system also includes a regulator valve disposed in the vapor path and arranged in series with the sensing valve, the regulator valve being configured to regulate the level of vacuum applied by a vapor pump to the sensing valve.

Abstract: A fluid supply system is provided which includes a filling station operable to provide a fluid to a fuel storage vessel. The fluid supply system is operable in a first mode to provide a fluid in a liquid phase from the filling station to the storage vessel and is operable in a second mode to prevent the supply of the fluid to the storage vessel. The storage vessel is in fluid communication with the fluid supply system and is operable to receive the fluid in the liquid phase when the fluid supply system is in the first mode and discharge the fluid in a gaseous phase to the filling station. At least one sensor is in communication with the discharge passage and the fluid supply, and operates to cause the fluid supply to operate in the second mode in response to a detected pressure drop.

Abstract: A fuel dispensing nozzle incorporating a double poppet valve assembly enables a user to more controllably and accurately dispense fuel through the nozzle. The double poppet valve assembly has a larger outer poppet and a smaller inner poppet, such that the user can open both poppets together or merely open the smaller inner poppet alone. The outer poppet enables a high rate of fuel to flow through the nozzle when the outer poppet is opened. The inner poppet, located within the body of the outer poppet, allows a reduced rate of fuel to flow through the nozzle when the inner poppet is opened but the outer poppet is closed, enabling the user to dispense more precise amounts of fuel.

Abstract: Improvements to filling valves of bottling plants in which the interruption of the processing fluids' flow happens automatically when the level of the liquid inside the filled bottle reaches the lower edge of the vent tube and the air trapped in the filling valve prevents the coming out of the liquid from the tank even if the external membrane (6) is still in the open position.

Abstract: An automatic shutoff device of the type which makes use of a venturi to terminate the flow of a liquid into a container when the liquid in the container reaches the level of the discharge tube. A movable housing is operatively positioned downstream of a constrictive nozzle giving rise to the venturi and a consequent low pressure area; the movable housing substantially encompasses the low pressure area except that the downstream end of the housing is open and may serve as a discharge tube from which liquid flows into the container to be filled, the filling operation continues until such time as the level of the liquid reaches the level of the discharge tube at which time liquid is rapidly drawn into the low pressure area causing the housing to move in the downstream direction thereby overcoming the restoring force of an associated spring biased valve causing the valve to seat to thereby substantially terminate the flow of liquid.
