Definitions

  • the field of the present invention relates generally to vapor recovery systems, and more specifically to fuel dispensing systems including a venturi aspirator for removing accumulated fuel from the vapor path of vapor recovery hoses included in such systems between the nozzle and meter housing.
  • vapor recovery system In fluid distribution systems, such as gasoline pumping systems for delivering gasoline to the fuel tank of the vehicle, environmental protection laws require that vapors emitted during the fuel dispensing process be recovered.
  • One such vapor recovery system includes a vapor recovery hose surrounding a product hose for delivering fuel to a nozzle, typically the nozzle of a gasoline pump. Vapors collected from the vehicle tank at the nozzle end are pushed by positive pressure which develops within the vehicle tank, normally called a balanced system, or sucked by a vacuum, from the nozzle back into the gasoline storage tank of the product distribution system via the vapor return path provided by the space between the coaxial product and vapor recovery hoses.
  • the invention disclosed includes a reservoir for collecting condensate from vapors that are flowing through a vapor return line of a fuel delivery system.
  • the reservoir is located within the gasoline dispenser housing of the system, remote from the separate and individual product delivery hose 36, and vapor return line 39.
  • Condensation that forms in a portion of a substantially overhead vapor return line 40 partly returns to the reservoir 20, from which it is returned to the product delivery hose via a product operated pump also located within the dispenser housing adjacent to the reservoir.
  • a venturi pump 3 is used to suck condensate from the reservoir into the product delivery line portion located within the meter housing. No teaching or suggestion of any apparatus or method for maintaining the vapor return line hose 39 free of liquid fuel is made or even alluded to.
  • the present invention includes venturi pump means located within the fuel flow path of a product hose for pumping out or aspirating liquid fuel that may accumulate in the vapor path of a vapor recovery hose that is either separate from or coaxial with and surrounding the product hose, and returning this fuel to the fuel flowing in the product hose, for maintaining the vapor path of the vapor hose clear for vapor flow between a nozzle and the metering housing.
  • Figure 1 shows that during refueling of an automobile 1, the liquid suction pump 15 is energized to suck away any liquid fuel entrapped in the vapor recovery line 5 via flexible hose 8. The unwanted fuel is discharged via outlet port 19 into the lower portion of the vapor recovery line 13, for return to an underground storage tank, in that example.
  • the invention generally includes a venturi liquid removal system 20 incorporated within hose 7 of the coaxial hoses 5, 7 and nozzle 3 assembly of a fuel distribution system.
  • a flexible tubing 22 is connected to the venturi pump or aspirator assembly 20, with the free end of the tubing 22 being located in an area of the vapor recovery hose 5 where liquid such as gasoline is expected to accumulate due to flowback from the nozzle 3 during the dispensing of fuel to a vehicle 1.
  • the venturi pump assembly 20 When fuel flows through the product hose 7, for delivery through the nozzle 3 to a vehicle 1, the venturi pump assembly 20 is operative by the flow of fuel to cause liquid accumulated in the vicinity of the free end of tubing 22 to be sucked back or aspirated through the tubing and into the fuel flowing from the venturi assembly 20 into the nozzle 3. In this way, the vapor path of the vapor hose 5 is maintained substantially clear of blockage by fuel that may overflow or "spitback" from the nozzle 3 into the vapor path, thereby permitting the free flow of vapors from the nozzle 3 back through the vapor path of vapor hose 5 to a collection point.
  • FIG. 3 One embodiment of the invention is shown in Figure 3, and includes a venturi assembly 20 mounted between the inlet end 24 of a nozzle 3 and the product delivery end 26 of a coaxial hose system, including an inner product delivery hose 7 surrounded by an outer vapor hose 5.
  • the venturi assembly 20 includes an outer tubular member 21 fabricated from a rigid material, such as appropriate metals, having threaded end portions 28 for connection to mating members of the nozzle 3 and vapor hose connection 6 as shown.
  • the venturi pump or aspirator 31 includes a rigid tubular housing 32 shaped as shown for enclosing a spring loaded poppet valve 34.
  • the poppet valve 34 has a centrally located rod-like member 36 ideally mounted within a tubular sleeve member 38, and a spring 40 for providing appropriate spring biasing of the poppet valve 34.
  • a rigid inlet tube 42 is provided for connecting the inlet hole 44 to the flexible hose or tubing 22, the latter which can be fabricated from polyethylene or butyl rubber, for example.
  • a flapper valve 46 serving as a check valve is preferably installed within the inlet tubing 42, for preventing gasoline or other liquid fuel product flowing through the product hose 7 from being forced into the vapor path of the vapor hose 5. In other words, the flapper valve 46 serves to insure that fluid can only flow in one direction, namely from the vapor path of vapor hose 5 to the venturi pump 31.
  • a suitable check valve 46 is believed to be a duck bill check valve manufactured by Vernay Laboratories, Inc., Yellow Springs, Ohio, 45387, under Vernay Part No. VA3426.
  • a filter screen 48 serving to filter out any contamination contained within the fuel sucked back to the venturi pump 31 via the tubing 22.
  • the filter substantially ensures reliable long-term operation of check valve 46.
  • Ring- like bushing members or spacers 50 are provided for maintaining the venturi housing 31 centered within the venturi assembly 20, as shown.
  • the rings or bushings 50 include a plurality of holes or openings 52 for permitting the free flow of vapors from a nozzle 3 to the vapor hose 5 as shown.
  • the flexible tubing 22 is passed through one of the holes in the ring or bushing member 50 associated therewith.
  • the product hose 7 for carrying fuel to nozzle 3 is connected to the inlet 54 of venturi 31 via O-ring seals 56, whereby the inlet 54 receives rigid hose connector 8.
  • the product outlet portion 58 of venturi housing 31 is coupled to the product inlet 60 of nozzle 3 via 0-ring seals 62.
  • the venturi pump or aspirator 31 is operative to draw fluid from areas within the vapor hose 5 where the fluid may accumulate (see Figure 2), through the inlet tube 42 and hole 44 for return to the product stream flowing through the product hose 7, as shown.
  • the spring loaded poppet valve 34 permits the venturi pump to draw fluid even at relatively low flow rates of product. As will be shown, unless it is necessary to produce adequate suction via the venturi pump 31 throughout a very wide range of product flow rate, including very low flow rates of product, the sprinq loaded poppet valve 34 may not be required.
  • the poppet 34 When the spring loaded poppet 34 is implemented, the poppet 34 is always located as shown for opposing the direction of product flow through the product hose 7 of the coaxial hose system 5, 7. Controlled loading by the spring 40 produces a small cross sectional flow area and consequent high velocity of product past the inlet hole 44. The high velocity product flow produces a low static pressure on the inlet tube 42, thereby providing the suction for aspirating accumulated product out of the vapor hose 5.
  • the one way check valve 46 prevents product from being pumped into the vapor path portion of the vapor hose 5 when the fuel is not flowing or the flow rate is low.
  • the venturi pump 31 can be located within the nozzle assembly 3, in certain applications.
  • the suction tube 22 would then be routed back from the nozzle 3 to the best position for removing accumulated product from the vapor path of the vapor hose 5.
  • the venturi pump 31, in this example could be placed between the nozzle valve housing and filler tube in the vapor recovery nozzle (not shown). The advantage of this latter approach is that at low flow conditions, no pressure would be applied to the poppet valve 34 or tube orifice 44, whereby the check valve 46 could be eliminated.
  • FIG. 4A A second and preferred embodiment of the invention is shown in Figures 4A through Figure 7.
  • Figure 4A a top view of the housing of the venturi pump 64 ultimately developed for use in product by the inventors is shown.
  • FIG 4B a sectional view taken along AA of Figure 4A is shown.
  • the venturi pump 64 is of a fixed throat design, in contrast to the variable throat design of Figure 3 provided by the poppet valve 34.
  • the dimensioning of the venturi chamber of the venturi pump 64 is considered critical to obtaining a low static pressure at the orifice 66 sufficient for continuously aspirating or sucking fluid out of the vapor hose 5 (for example) over a given range of flow rate of product.
  • the present inventors designed the venturi pump 64 to provide low enough static pressure for adequate aspiration away from the vapor path of the vapor hose 5 over a product flow rate range of 6.5 to above 10.0 gallons per minute of gasoline, in this example.

  • the outlet end 108 is coupled to the inlet hole or port 98 of venturi pump 64.
  • the other end 110 is configured for coupling to a flexible tube 112, as shown in Figure 7.

  • An end view of the assembly taken from the inlet 68 end is shown in Figure 6B.
  • FIG 7 a partially exploded, partially cutaway assembly view is shown of one application of the subject invention.

  • Clamps 118 are used for securing the product return tubing 112 and suction head 116 to the product hose 120, for example.
  • Outer vapor hose 122 surrounds the product hose 120, to form a coaxial hose assembly 82.
  • This coaxial hose assembly 82 is rigidly connected to a coupling connector 124 for connection to the product feed and vapor return lines of a fuel dispensing system (not shown), for example.
