A fuel storage and supply arrangement serves as a source of fuel to be dispensed via at least one fuel dispenser in a fuel dispensing environment. The arrangement comprises a storage tank for containing a quantity of the fuel. A pump assembly draws the fuel from the storage tank providing the fuel under pressure to a fuel supply line. A fuel conditioning assembly includes a housing having a storage volume, a housing inlet receiving the fuel under pressure created by the pump assembly, a housing outlet through which fuel exits the housing, and a housing port through which fuel can be drawn into the housing. A vacuum source in fluid communication with the housing outlet is operative to selectively apply a vacuum to the outlet of the housing so that liquid can be drawn into the housing via the port. A water intake device is in fluid communication with the housing port. The water intake device has at least one inlet situated adjacent to a bottom of the fuel storage tank.

A fluid exchanger may exchange a fluid (e.g., coolant) in a reservoir (e.g., vehicle radiator) by removing or withdrawing a first fluid (e.g., old, spent, used, etc.) and by introducing a second fluid (e.g., new, clean, etc.). For example, the fluid exchanger may use a negative pressure, suction, or vacuum to draw the first fluid from the reservoir, and subsequently, the second fluid may be transferred into the reservoir using a negative pressure held in the reservoir, a positive pressure applied to the second fluid, or a combination thereof. The fluid exchanger may also include a multi-purpose, hand-held nozzle that can change an operation of the fluid exchanger from a withdrawing mode to a dispensing mode.

A fluid delivery system or method for the same may include features or steps for dispensing, via a nozzle, a first fluid from a first fluid storage tank of at least two fluid storage tanks. The fluid storage tanks may be separately fluidly coupled to a manifold via respective fluid supply lines. A fluid delivery line fluidly may couple the nozzle to the manifold. A residual first fluid may remain within the delivery line after the dispensing step. The system or method may further include features or steps for connecting the nozzle to a clearance tank. A clearance outlet line may fluidly couple the clearance tank to the manifold. The system or method may further include features or steps for purging the residual first fluid from the fluid delivery line into the clearance tank and delivering the residual first fluid from the clearance tank to the first fluid storage tank.

A float controlled nozzle valve for use in a fuel nozzle, to provide for gradual delivery of fuel to a fuel tank, the nozzle, having a housing, including a generally horizontally arranged spout, and embodying a float rod and float assembly, which act upon a valve provided within the nozzle housing, to detect and provide for the flow of fuel into an associated fuel tank, or to curtail the same. The float rod pivotally mounts within the nozzle housing, contains an adjustment screw, which can bias against a valve pin to determine when a valve ball is to be opened from its valve seat, to allow the passage of fuel, or when the valve ball is allowed to seat upon its valve seat, to curtail the further flow of fuel. The nozzle housing is provided for securement to the fuel tank, for which it detects the level of fuel within the tank, to determine when an additional supply of fuel is to be dispensed by way of the nozzle, into its associated fuel tank.

A system for dispensing a gaseous fuel from a liquefied fuel and a method for operating such a system are provided. The system includes a storage tank, a pressure sensor, a dispenser, a temperature sensor, and a vapor supply unit. The storage tank stores a liquefied fuel including phases of liquid and vapor. The pressure sensor is configured to measure a vapor pressure inside the storage tank. The dispenser is configured to receive the liquefied fuel and dispense the gaseous fuel to a receiving tank. The temperature sensor is configured to measure temperature of the dispenser. The system further includes a vapor supply unit fluidly coupled with the storage tank and configured to provide the vapor of the liquefied fuel from the storage tank into the dispenser or in thermally contact with at least one portion of the dispenser.

A float probe configured to regulate fluid flow into a fluid container is disclosed. The float probe comprises an upper assembly having one or more outlets, a plurality of rods extending from the upper assembly to a lower assembly and a float assembly disposed between the upper assembly and the lower assembly. A first distal end of the rods is coupled to the upper assembly and a second distal end of the rods is coupled to the lower assembly. The rods extend along an outer surface of the float assembly and the float assembly is movable along the rods between a first position proximate to the upper assembly and a second position proximate to the lower assembly. The float assembly prevents fluid flow out of the outlets when disposed in the first position.
