- An independently significant facet of the invention resides in a fuel pickup comprising a flexible conduit supporting, in consecutively axially displaced relation, elastomeric wick gripping means, elastomeric mounting means, and elastomeric seal means engageable with a fuel conduit.
- the elastomeric seal means and the elastomeric mounting means are spaced axially of the conduit and are able to be mutually displaced while remaining operable to perform their mounting and sealing functions.
- FIGURE l provides a sectioned view of a fuel tank and fuel pickup unit illustrating positional relationships existing between the fuel tank, the fuel pickup, and a conduit leading to a fuel pump;
- FIGURE 2 provides an enlarged, partially sectioned, perspective view of a exible conduit incorporated in the FIGURE l assembly, which conduit serves to support a Wick-like web;
- FIGURE 3 provides a longitudinally sectioned illustration of a modified wick or web clamping arrangement which may be incorporated in the flexible conduit shown shown in FIGURES 1 and 2.
- FIGURE 1 illustrates, in a sectioned format, the general structural details of an assembly comprising a fuel tank 1, a fuel pickup 2, and a conduit 3 leading to a fuel pump.
- Reservoir or fuel tank 1 is defined by wall means including a generally cup-like portion 4 and an end Wall 5.
- End Wall 5 may be joined to cup portion 4 by conventional, adhesive fastening joint means v6 so as to form a closed fuel reservoir 7.
- Conduit 3 comprises an L-shaped conduit portion including a leg 8 communicating with the fuel pickup unit 2 and another leg 9 leading to a fuel pump, not shown.
- a wire screen filter unit 10 may be mounted in the leg 8 and supported on an angular ledge 11. The function of this screen 10 is to prevent solid materials from having access to the interior of the conduit 3 when the fuel conduit 3 is separated from the fuel tank or reservoir 7.
- Fuel pickup unit 2 includes, as one of its principal components, a rectangular sheet 12 of wick material such as felt. As will be apparent, however, sheet 12 may assume a variety of peripheral configurations, i.e., it has a circular periphery, an irregular periphery, etc. This web-like member 12 provides capillary passage means operable to transmit fuel in virtually any direction along the median plane of the web unit. v
- Pickup unit 2 also comprises an elastomeric and laterally flexible somewhat beam-like conduit 13.
- Conduit 13 is fabricated, for example, from oil and gasolene resistant synthetic rubber 'such as buna-N. Obviously, other commercially available gasolene resistant, elastomers may be employed in fabricating the conduit 13.
- conduit 13 intersects a generally median portion of the web 12.
- the web 12 radiates outwardly from the conduit 13 in all circumferential directions, i.e., the body of the web 12 fully encircles the conduit 13.
- Conduit 13 includes yieldably deformable clamping means 14.
- This yieldably deformable clamping meansv 14 serves to detachably mount the web means on the left end portion of the conduit 13, viewing the apparatus as "u shown in FIGURE 1. 'With this mounting arrangement, the web 12 extends transversely of the conduit 13 and provides capillary passage means encircling and radiating outwardly from this conduit.
- a press-lit connecting means 15 is formed integrally with the conduit 13 and mounts the conduit 13 in a mounting laperture 16 formed in reservoir wall 5.
- a radially compressible, elatomeric, and deformable seal portion 17 formed on the right end of conduit 13 is telescopingly ⁇ and sealingly received within the left end ofthe leg 8 of conduit 3.
- Passage means 18 of the conduit 13 provides fluid communication between the capillary passage means of the web 12 and the interior passage 19 of the L-shaped conduit segment 3.
- the clamping means 14 includes a first, annular, elastomeric and yieldable rim 20.
- Rim 20 is carried by and formed integrally with the conduit 13. As illustrated in FIGURE 1, rim 20 is disposed in substantially conforming and clamping engagement with one side 21 of the web 12.
- a second, annular, elastomeric and yieldable rim 22 is formed integrally with the conduit 13. This second rim 22 faces and is spaced axially from the first rim 20. Rim 22 is disposed in substantially conforming and clamping engagement with the other side 23 of the web 12.
- a first, annular, elastomeric and yieldably detlectable disc spring 24 is formed integrally with, and interconnects the conduit body 13 with the rim 20.
- This disc l spring 24 is operable, by virtue of its resilience, to yieldably maintain the rim 20 in generally conforming engagement with the side 21 of the web 12.
- a second, annular, elastomeric and yieldably deflectable disc spring 25 is formed integrally with and interconnects the conduit body 13 of the rim 22. This disc spring 25 serves to yieldably maintain the second rim 22 in generally conforming engagement with the other side 23 of the web 12.
- the opposing faces 26 and 27 of the rims 20 and 22, respectively are normally and desirably parallel and aligned with planes perpendicular to the longitudinal axis of the central passage 18 when the conduit is straight.
- the sides 21 and 23 of the web 12 are desirably, more or less parallel to each other so as to enable the faces 26 and 27 to simultaneously engage the web sides while remaining parallel.
- the yieldable and resilient nature of the rims 20 and 22 enables the faces 26 and 27 to accommodate to limited 4 irregularities in the web sides 21 and 23 so as to provide effective conforming engagement between the rims 20 and 22 and the web 12.
- the faces 26 and 27 are able to flex to follow irregularities in the thickness of the web or to follow the web sides even when the sides are not mutually parallel.
- the disc springs 24 and 25 provide a unique, resilient, pivotlike support for the rims 20 and 22.
- the resiliency of the disc spring enables the rims to pivot in multiple directions, i.e., undergo a universal pivot action, with respect to the longitudinal axis of the beam 13.
- the rims 20 and 22 are able to conformingly engage opposite sides of the web 12 even while oriented in a skewed relationship.
- each of the rim faces 26 and 27 engages the web so as to provide a barrier, preventing the passage of air around the outside of the web and into passage means 18.
- this air seal ensures that fuel only is transmitted to the passage means 18 and that this fuel moves through the controlled influence of the capillary passage means provided by the web 12.
- the disc springs 24 and 25 tend to maintain the rims 20 and 22 in the neutral position, shown in FIGURE 2, with there being a predetermined axial spacing between the rim faces 26 and 27. In this fashion, the compressive engagement between the rims and the web is limited so as to avoid undue crushing of the capillary passages in the web.
- the spring action of the radially extending webs or disc springs 24 and 25 will serve to maintain the flange surfaces 26 and 27 in engagement with the web sides 21 and 23, with the faces 26 and 27 being biased into contact with the web sides.
- the passage means 18 comprises a central passage portion 28 extending longitudinally of the conduit 13. Passage means 18 also includes an annulus 29 interposed auxiliary between the disc springs 24 and 25. As illustrated, the rims 20 and 22 project axially in opposite directions, somewhat across the outer periphery of this annulus 29, i.e., the rims overlap the outer periphery of annulus 29.
- First and second annular ledges 30 and 31 are spaced axially or longitudinally of the conduit 13. These ledges are interposed radially between the axis of the passage portion 28 and the annulus 29.
- An annular groove 32 is formed in the body of the conduit 13 and is disposed radially inwardly of the annulus 29 and axially between the ledges 30 and 31.
- a generally radially extending passage 33 intersects the closed, right end of the passage 28 so as to provide port means 34 and 35. Each of these port means 34 and 35 provides fluid communication between the central passage 28 and the annular groove 32.
- the annular groove 32 in turn communicates wtih the annulus 29 and an aperture 36 formed in the web 12.
- the aperture 36 is disposed in a generally intermediate location within the web 12.
- the conduit 13 is assembled with the web 12, as shown in FIGURE 1, so as to position the rims 20 and 22 on opposite sides of the web with the aperture 36 located within the annulus 29 in lluid communicating relation with the port means 34 and 35.
- the ledges 30 and 31 insure that the wall 37, which defines the web aperture 36, does not directly engage the base 38 of the groove 32. In this manner, there is provided an unobstructed annular groove 32 which promotes an unobstructed transfer of fluid from the capillary passages of the web 12 to the transfer ports 34 and 35.
- the press-fit connecting means 15 includes a first annular collar 39 projecting radially of the longitudinal axis of the conduit 13.
- a second collar 4f spaced axially of conduit 13 to the right of collar 39, also projects radially of the conduit axis.
- a frustoconical guide cone 41 is carried by and formed integrally with the collar 40. Guide cone 41 converges away from the collars 39 and 40 and toward the seal means 17.
- Collars 39 and 49 deline an annular groove 42 interposed axially between these two components of the conduit 13.
- the base 43 of the groove 42 is disposed in generally planar alignment with the wall 44 of the aperture 16. As illustrated, groove base 43 is desirably aligned in abutting and therefore sealing engagement with the aperture wall 44. This sealing engagement may be enhanced by a limited interference lit between the walls 43 and 44. This interference t of course may result by having the diameter of the cylindrical groove base wall 43, in its relaxed state, exi;
- the seal means 17 includes a frustoconical guide cone 46.
- Guide cone 46 is spaced axially to the right of pressfit connecting means and converges generally away from this press-fit connection.
- the largest portion 47 of guide cone 46 is disposed in an interference fit relationship with the inner wall 48 of conduit leg 8. This interference fit notwithstanding, guide cone portion 47 is disposed in telescoping and sealing engagement with the wall 48.
- the conduit 13 also includes a plurality of standoff lugs or supports 49. Such standoff supports 49 are iluustrated in perspective view in FIGURE 2.
- the wick or web 12 is assembled on the conduit 13.
- This assembly may be accomplished by grasping the rim at the locations 20a and 2011 and then pulling these rim portions to the left so as to fold the rim 20 and the disc spring 24. With these components thus folded so as to have reduced their width about in half, in the axial direction of the conduit, the folded spring 24 and rim 20 may then be inserted through the aperture 36 of the web 12. After the folded spring and rim have been thus pushed through the Wick aperture, the rim portions 20a and 2011 may be released so as to allow the rim and spring to elastically restore to their normal positions illustrated in FIGURE l. In this restored or normal condition of the rim 2t) and the rim 22, these rims conformingly engage the felt sides 21 and 23 so as to provide air seals.
- the press-lit unit 15 is assembled in the aperture 16. This is accomplished by moving the seal end 17 of the conduit 13 axially to the right through the aperture 16. During the initial portion of this axial movement, the cone 46, which is smaller in diameter than the aperture 16, moves freely through the aperture 16. The tapering nature of cone 46 facilitates the entry of conduit 3 into aperture 16. During the latter part of this axial movement, the guide cone 41 facilitates the resilient construction of the collar so as to enable the collar 40 to be pressed through the aperture 16 into its stabilizing or locking position on the right side of the aperture 16, viewing the apparatus as shown in FIGURE l. When the collar 40 resiliently enlarges, the left-most collar 39 will preferably be in abutting engagement with the left side of the collar adjacent the aperture 16.
- this wall may then be assembled with the cup portion 4 of the reservoir and joined by conventional metal adhesive joining techniques.
- the assembled wick and conduit may be inserted through a conventional fuel cap or iiller hole in reservoir 7 and be manipulated so as to cause the press-tit portion 15 to be engaged with the aperture wall portion 45.
- the reservoir 1, now including the fuel pickup, may be installed on an engine and the seal 8 telescopingly assembled with the fuel conduit 3 which is mounted on the engine.
- the guide cone 46 serves a multiple, guide function. It first facilitates the entry of the conduit 13 through the aperture 16. It then functions to facilitate the entry of the seal 17 into the aperture 48.
- the axial displacement of the seal 17 from the pressfit portion 15 provides a uniquely significant, assembly advantage.
- Substantial axial misalignnient on the order of up to about .l2 inch may exist between the conduit leg S and the aperture 16, with press-fit portion 15 being maintained in aperture 16 and seal means 17 being fully operable.
- This displacement may cause the portion of the conduit 13 between the portions 15 and 17 (which may have a length of about .19 inch, an outside diameter of .25 inch, and an inside diameter of .09 inch) to be exed.
- the assembly of the Wick 12 and conduit 13, and the mounting of these assembled components on the wall 5, is effected without any tools or supplementary fasteners. Further, there is no critical alignment criteria.
- FIGURE 3 illustrates an alternative structure which may be employed to secure the wick 12.
- a modified conduit 51 includes the previously discussed press-tit mounting means 15 and the seal 17. However, this modified conduit 51 incorporates a modified, press-tit, separable clamp 52.
- This separable clamp 52 comprises a separable cap portion 53 including a shank 54 and a frustoconical, presst locking portion 55.
- This press-tit portion being resilient and fabricated of material such as buna-N, is pressfit assembled into a frustoconical aperture 56 formed in the body 57 of the modified conduit 51.
- radially extending anges 58 and 59 of portion 55 and body 57, respectively, serve to yieldably or detachably anchor the cap 53 onto the body 54.
- Assembly of the felt wick 12 on the modified conduit 51 is effected by first inserting the fastening portion 55 through the felt aperture 36.
- the press-fit head is then inserted into the aperture 56.
- air sealing flanges 6G and 61 are brought into sealing and conforming engagement with the sides 21 and 23 of the wick or web 12.
- the disc-spring like portion of cap 53 extending V generally radially inwardly of flange 60 provides a generally constant clamping force on web 12.
- Fluid transmitted by the web 12 to the aperture 36 enters an annulus 62 which communicates with a radially extending passage 63 formed in the shank 54.
- This passage in turn communicates with a longitudinally extending central passage 64 of the cap unit 53.
- Center passage 64 communicates with a central passage 65 of the main body portion 57 so as to thereby provide a flow path leading to and terminating Within the seal 8.
- this modified unit may be assembled with a fuel tank and pump line in the manner previously described in connection With the FIGURE l embodiment.
- a principal advantage of the invention resides in the vastly simplified structure of a wick type fuel pickup.
- a one or two piece mol-ded assembly takes the place of a number of separate elements previously utilized.
- This molded, flexible conduit may be expeditiously assembly with a wicking felt by using either the folded technique described in connection with the FIGURE 1 embodiment or the press-fit technique described in connection with the FIGURE 3 embodiment. Either of these techniques may be effected without recourse to tools or separate fasteners and without adhering to precision alignment criteria.
- the assembled conduit and wick may then be mounted in the wall of a fuel tank by the simple use of passing the press-fit portion of the conduit through an aperture in a fuel tank wall.
- no tools or separate fasteners are required.
- the wick 12 in extending transversely of the conduit 13 for a substantial areal extent, is able to absorb fuel from virtually all portions of the interior of the reservoir 7. This absorption may result either from immersion of the wick 12 or from splashing of fuel onto the wick.
- connection of the conduit to a fuel pump is effected without separate fasteners or tools.
- the structure of this invention provides a more eliicient fuel pickup unit characterized by clearly enhanced structural simplicity. This structure totally eliminates the necessity for extraneous fasteners or tools.
- the air seals provided by thus unit are capable of conforming to limited irregularities in the wick so as to provide a more effective overall seal. Because of the resilient nature of the disc springs which support the rim type air seals, these will remain functional even though they may be canted with respect to each other.
- the disc springs provide for a highly controlled clamping action which minimizes adverse felt crushing forces. With the disc springs tending to not converge beyond their neutral position, it is ensured that the felt will not be crushed beyond the gap which exists between the rims when their supporting disc springs are unstressed. With this controlled clamping, the felt Wick may be dimensioned so as to ensure that excessive crushing does not take place.
- the spring-like flanges 24 and 25 function to cause the Hangs 22 and 20 to maintain a substantially uniform squeezing action on the wick 12.
