Description

    FIELD OF THE INVENTION
  • [0001]
    This invention relates to systems for transferring fluids and, more particularly, to systems for siphoning liquids from a supply container to a receiving container.
  • BACKGROUND OF THE INVENTION
  • [0002]
    Transferring liquids from a supply container to a receiving container by means of siphoning requires that the supply container be disposed in an elevated position relative to the receiving container. Typically, during siphoning, the supply container is supported on a relatively flat surface, such as a table. When siphoning from a supply container, the siphoning apparatus tends to be extended as close to the receiving container as possible. This creates risk of pulling the gas container and siphoning apparatus from the flat surface of the table, causing the system to fall to the ground, causing undesirable spillage of liquid (e.g. gasoline). Further, dedicating space on a table for supporting the siphoning system takes up unnecessary floor space.
  • SUMMARY OF THE INVENTION

  • DETAILED DESCRIPTION OF THE INVENTION
  • [0043]
    Referring to FIG. 1, the present invention provides a system 10 for effecting transfer of liquid from a supply container 100 to a receiving container 300 comprising a support structure 400 and a fluid transfer apparatus 200.
  • [0044]
    The support structure 400 is configured to support the supply container 100. The support structure 400 includes a base 412 for vertically supporting the supply container 100, as well as lateral support means 414 projecting above the base 412 for providing lateral support to the supply container 100 supported on the base 412. The lateral support means 414 includes at least two pairs of opposing sidewall sections 416, 418, and 420, 422. Each of the sidewall sections 416, 418 and 420, 422 presents an inwardly facing planar lateral support surface which is orthogonal to the upwardly facing vertical support surface presented by the base 412. The planar lateral support surface of each of the sidewall sections 416, 418 and 420, 422 is orthogonal to the planar lateral support surface of each of the sidewall sections. Preferably, the sidewall sections 416, 418 are coupled to the sidewall sections 420, 422 to define a receptacle 424 for receiving the supply container 100. Preferably, the support structure is made from high density polyethylene.
  • [0045]
    Mounting means 440 of the support structure 400 is configured to effect mounting of the support structure 400 to a mounting surface having a transverse axis perpendicular to a transfer axis of a horizontal surface. For example, the mounting surface can be in the form of a wall 600 extending upwardly from a horizontal floor. Referring to FIG. 2, in the embodiment illustrated, the support structure 400 includes a connector hook 442 configured to be received by a bracket 444. To receive the connector hook 442, the bracket 444 includes receptacle 446. The bracket 444 is mountable to the wall 600 by means of screws 448.
  • [0046]
    Optionally, the support structure 400 can include a paper towel dispenser 450 projecting below the base 412. Additionally, a divider 426 can be provided to divide the compartment 424 into two separate compartments, such that one compartment can contain the supply container 100, and the other compartment can be configured to contain accessories such as engine fluids.
  • [0047]
    The fluid transfer apparatus 200 is provided to effect creation of a fluid pressure driving force for initiating flow of the liquid from the supply container 100 when the supply container 100 is supported on the support structure 400. In this respect, the fluid transfer apparatus 200 is configured for fluid communication disposition with the liquid in the supply container 100. The fluid transfer apparatus 200 also includes an outlet 218 for effecting discharge of the liquid flowed to the receiving container 300 from the supply container 200.
  • [0048]
    The fluid pressure driving force created by the fluid transfer apparatus 200 can take the form of a communication of a reduced fluid pressure to the liquid in the supply container 100, wherein such reduced fluid pressure is less than the fluid pressure of the liquid in the supply container 100. Such created fluid pressure differential initiates flow of the liquid from the supply container 100 through the fluid transfer apparatus 200.
  • [0049]
    A fluid transfer apparatus 200 which also falls within the scope of the invention is one which, when disposed communication with the liquid in the supply container 100, is capable of initiating and effecting siphoning of the liquid from the supply container 100. The term “siphoning” is used herein to describe the process by which a liquid is transferred from a supply container 100 at a higher level, and over an intermediate elevation greater then the higher level, and then discharged at a lower level. Such transfer is effected by the pressure of the fluid in the supply container 100 forcing the liquid from the supply container 100 to the intermediate elevation. The excessive weight of the liquid in the fluid passage between the intermediate elevation and the discharge causes a continuous flow to be discharged.
  • [0050]

  • [0063]
    An example of a suitable fluid transfer apparatus is the Flo'N Go™, manufactured by Scotia Innovators Inc.
  • [0064]
    A further example of a suitable fluid transfer apparatus 200 is illustrated in FIG. 5. It is understood that any one of a number of fluid transfer apparati can be used in the present invention. FIG. 5 illustrates a fluid transfer apparatus 200 for initiating and effecting siphoning of a liquid from a supply container 100. It is understood that other devices which are capable of initiating siphoning, but configured in a different manner, fall within the scope of the invention.
  • [0065]
    Referring to FIGS. 6-9, the fluid transfer apparatus 200 includes a fluid passage 214 having an inlet 216, and an outlet 218, and an orifice 219. The inlet 216 is configured for fluidly communicating with the supply container 100. A portion of the fluid passage 214 including the inlet 216 is defined by a flexible hose. To effect fluid communication with the liquid in the supply container 100, the hose is inserted through an opening in the supply container 100 and disposed below the liquid level in the supply container 100. Optionally, a shut-off valve 500 can be interposed between the inlet 216 and the supply container 100 (see FIG. 1).
  • [0066]
    The outlet 218 communicates with atmospheric pressure, and is configured for effecting discharge of liquid being flowed through the fluid passage 214 to the receiving container to effect transfer of liquid from the supply container 100 to the receiving container 300. The orifice 219 effects fluid communication between the inlet 216 and the outlet 218, and is defined by a valve seat 221. A fluid flow actuator 225 is provided to initiate flow of liquid from the supply container 100 and through the apparatus 200.
  • [0067]
    A valve 223 is provided and configured to control or prevent flow of fluid between the inlet 216 and the outlet 218. The valve 223 includes a sealing member 232 configured to sealingly engage a valve seat 221. Sealing engagement of the sealing member 232 to the valve seat 221 effects sealing of fluid communication between the inlet 216 and the outlet 218. A valve stem 234 joins the sealing member 232 to a male retaining bulb 236. The retaining bulb 236 is received within a female retaining bulb 238 provided within an expandable bellows 220 of an envelope 280. The envelope 280 is disposed between first and second valve means 224, 226 in the fluid passage 214. In this respect, the envelope 280 defines a space 222 for receiving a gas or a gas/liquid mixture.
  • [0068]
    Expansion and compression of the bellows 220 effects displacement of the sealing member 232 relative to the valve seat 221. The bellows 220 is spring biased towards an expanded condition. When the bellows 220 is in the expanded condition, the sealing member 232 is sealingly engaged to the valve seat 221.
  • [0069]
    The bellows 220 further functions as the flow actuator 225. Manual actuator 228 effects deformation of the bellows 220. Deformation of the bellows 220 effects a contraction of the space 222 to a contracted condition. In concert, the sealing member 232 becomes displaced from the valve seat 221. When the space 222 includes a liquid and/or gas, the deformation of the bellows 220 results in the contraction of the space 222, and displacement of the valve member, to thereby effect a discharge of at least a portion of the fluid from the space 222, through the orifice, past the first valve means 224, and to the outlet 218.

    To prevent a return of the exhausted gas to the space 222 of the envelope 280, the first valve means 224 is disposed in the fluid passage 214 downstream of the orifice 219 to function as a check valve for preventing back flow of gas or a gas/liquid mixture from the outlet 218 and into the space 222. The first valve means 224 is biased by a first biasing force to assume a normally closed condition, whereby fluid communication between the space 222 and the nozzle outlet 218 is sealed. The first valve means 224 is configured to assume an open condition, whereby fluid communication is effected between the space 222 and the outlet 218 to effect the transfer of fluid from the space 222 and out through the nozzle outlet 218. This condition is assumed in response to a communication of an increased fluid pressure in the space 222 attributable to the contraction of the space 222, such contraction effecting a fluid pressure differential between the space 222 and the outlet 218. The resultant fluid pressure differential force acts on the first valve means 224 and eventually overcomes the first biasing force. Once the fluid pressure in the space 222 approaches the fluid pressure at the outlet 218, the first biasing force effects return of the first valve means 224 to the closed condition, thereby sealing fluid communication between the space 222 and the outlet 218. The first valve means 224 is configured to maintain the closed condition when the fluid pressure in the space 222 is less than the fluid pressure downstream of the first valve means 224, such as at the outlet 218. In the embodiment shown, the first valve means 224 is a flapper valve.
  • [0071]
    A second valve means 226 is also provided in the fluid passage 214, also functioning as a check valve, for preventing back flow of gas or a gas/liquid mixture from the space 222 to the inlet 216 (and to the container 100). The second valve means 226 is biased by a second biasing force to assume a normally closed condition, whereby fluid communication between the space 222 and the inlet 216 is sealed. The second valve means 226 is configured to assume an open condition, whereby fluid communication is effected between the inlet 216 and the space 222 to effect a transfer of fluid (gas and/or liquid) from the inlet 216 to the space 222 in response to communication of a decreased fluid pressure in the space 222 attributable to the expansion of the space 222 from the contracted condition, such expansion effecting a fluid pressure differential between the inlet 216 and the space 222. The resultant fluid pressure differential force acts on the valve means 226 and is eventually sufficient to overcome the second biasing force. Once the fluid pressure in the space 222 approaches the fluid pressure at the inlet 216, the second biasing force effects return of the second valve means 226 to the closed condition, thereby sealing fluid communication between the space 222 and the inlet 216. The second valve means 226 is configured to maintain a closed condition when the fluid pressure in the space 212 is greater than the fluid pressure upstream of the second valve means 216, such as at the inlet 216. In the embodiment shown, the second valve means 226 is a flapper valve.
  • [0072]
    To effect contraction and expansion of the space 222, the bellows 220 is coupled to the manual actuator 228. As shown, the manual actuator 228 comprises a hand lever 230. Referring to FIG. 4, the hand lever 230 is pivotally coupled to a frame 231 of the apparatus 200. Pressing on the hand lever 230 effects the deformation of the bellows 220, resulting in contraction of the space 222 and displacement of the sealing member from the valve seat (opening of the orifice). Releasing the lever 230, when the space 222 is in the contracted condition, results in expansion of the space 222 and its return to an original expanded condition and also results in return of the sealing member into sealing engagement with the valve seat 221.
  • [0073]
    The fluid transfer apparatus 200 is useful for effecting siphoning of liquid from container 100 where the level of the liquid in the supply container 100 is elevated relative to the discharge of the dispensing apparatus 200 and a receiving container 300. To effect flow of liquid from the container 100, and its eventual discharge through outlet 218, hand lever 230 is pressed. Pressing of hand lever 230 causes pivotal rotation of the hand lever 230 so that hand lever 230 comes into contact with and presses against the bellows 220. As the hand lever 230 presses against the bellows 220, the bellows 220 deforms, with consequent contraction of the space 222, and displacement of the sealing member 232 from the valve seat 221. Upon contraction of the space 222, fluid (liquid and/or gas) within the space 222 becomes pressurized. This fluid pressure eventually overcomes the biasing force being applied to the valve means 224, and effects opening of valve means 224 such that fluid communication is effected between the space 222 and the outlet 218. As a result, fluid flows from the space 222 and discharges from the nozzle 218, thereby effecting at least partial evacuation of the space 222. Eventually, the fluid pressure within the space 222 subsides such that the valve means 224 returns to a closed position, sealing fluid communication between the space 222 and the outlet 218.
  • [0074]
    Once the space 222 is at least partially evacuated and the valve means 224 has returned to a closed condition (or is disposed to return to a closed condition upon creation of a sufficient vacuum as described hereafter), release of the hand lever 230 effects expansion of the bellows resulting in reduced pressure condition in the space 222 relative to the fluid pressure of the liquid in the supply container 100. This vacuum condition forces open the valve means 226 (and, if not closed already, effects closure of valve means 224), and provides a driving force to effect flow of fluid (liquid and/or gas) from the supply container 100.
  • [0075]
    The priming action of effecting alternating contraction/expansion of the space 222 eventually results in the fluid passage being occupied by liquid from the supply container 100. When this happens, a siphoning process is established as the fluid pressure of the liquid will keep the first valve means 326 open, and liquid flow will continue so long as the liquid level in the supply container 100 is elevated relative to the outlet 218 of the apparatus 212. The rate of liquid flow during siphoning may be controlled by the hand lever 230. If desired, the siphoning process can be stopped by sufficiently pressing on the hand lever to cause sealing engagement of the valve 223 with the valve seat 221.

    It will be understood, of course, that modifications can be made to the embodiments of the invention described herein without departing from the scope and purview of the invention as defined by the appended claims.
