Definitions

  • This invention relates generally to an assembly for filling a closed interior chamber and more particularly to an assembly for filling a transmission with a liquid lubricant.
  • one chamber may hold engine lubricating oil, another may hold transmission fluid, still another may hold brake fluid, etc.
  • a dip stick To determine when a particular chamber must have fluid added, it is customary and convenient to utilize a dip stick.
  • the present invention is directed to overcoming one or more of the problems as set forth above.
  • an assembly for adding oil to a closed interior chamber defined by a case.
  • a filler tube structure having input and exit portions has the exit portion thereof in communication with a top portion of the chamber.
  • a dip stick guide tube structure has an interior passage in which a dip stick normally fits.
  • the upper end portion of the guide tube structure is positioned adjacent and generally parallel to the input portion of the filler tube structure.
  • a tubular fitting is provided which has first and second end portions with the first end portion being circumferentially sealed to the upper portion of the guide tube structure and to the input portion of the filler tube structure.
  • the cap is removably attachable in covering relation with the second end portion of the tubular fitting.
  • Figure 1 illustrates, in side partial view, partially in section, an embodiment of the present invention
  • Figure 2 illustrates a partial view taken along the line II-II of Figure 1;
  • Figure 3 illustrates a view taken along the line III-III of Figure 2, somewhat enlarged.
  • Figure 4 illustrates, in enlarged view, a portion of an alternate embodiment of the present invention.
  • Figure 1 shows an assembly 10 for adding a liquid to a closed interior chamber 12 defined by a case 14.
  • the chamber 12 has a top portion 16 and a bottom portion 18.
  • the case 14 would be the case for a transmission (not illustrated), in accordance with the preferred embodiment of the invention.
  • a filler tube structure 20 has an input portion 22 and an exit portion 24.
  • the exit portion 24 is in communication with the top portion 16 of the chamber 12.
  • the input portion 22 is generally above the exit portion 24 so as to provide gravity driven
  • a bore 26 is formed in a flange 28 which extends generally upwardly from the case 14.
  • the exit portion 24 of the filler tube structure 20 is connected to the bore 26 which then communicates with the top portion 16 of the chamber 12.
  • a dip stick guide tube structure 30 has an interior passage 32 for receiving a dip stick 34.
  • the dip stick guide tube structure 30 has an upper end portion 36 and a lower end portion 38.
  • the upper end portion 36 is positioned adjacent and generally parallel to the input portion 22 of the filler tube structure 20.
  • the upper end portion 36 of the guide tube structure 30 is positioned generally above the input portion 22 of the filler tube structure 20. In this manner, when fluid is added to the input portion 22 of the filler tube structure 20, it will generally not flow into the upper end portion 36 of the guide tube structure 30.
  • a tubular fitting 40 having a first end portion 42 and a second end portion 44, has the first end portion 42 thereof circumferentially sealed to the upper end portion 36 of the guide tube structure 30 and to the input portion 22 of the filler tube structure 20.
  • a wall 46 is formed across the first end portion 42 of the tubular fitting 40, with the wall 46 having a first hole 48 to which the input portion 22 of the filler tube structure 20 is sealingly attached.
  • the wall 46 also has a second hole 50 to which the upper end portion 36 of the guide tube structure 30 is sealingly attached.
  • the dip stick 34 is adapted to fit in the interior passage 32 of the guide tube structure 30.
  • the dip stick 34 has a lower end 54 and an upper end 56, and a handle 52 is attached adjacent the upper end 56 and is of a size and construction to fit within the tubular fitting 40.
  • a cap 58 normally of a conventional variety and having conventional pressure release threads to allow release of internal pressure prior to removal and to thereby prevent splattering out of fluid, is removably attachable in a covering, generally sealing, relationship with the second end portion 44 of the tubular fitting 40.
  • the handle 52 of the dip stick 34 is also of a size and construction to be free from interference with the cap 58. In this manner, anyone wishing to add fluid to the chamber 12 and removing the cap 58 will immediately find the handle 52 of the dip stick 34.
  • a venting structure 60 serves for venting air which may become entrapped in the chamber 12 on addition of fluid thereto via the filler tube structure 20.
  • the venting structure 60 includes a venting passage 62 having one end 64 communicating with the top portion 16 of the chamber 12 and having another end 66 communicating with the interior passage 32 at a location external of the case 14.
  • the vent passage 62 includes a first portion 68 communicating the top portion 16 of the chamber 12 with a block 70 which is attached., for example by bolts 72 (see Figures 1 and 2) to the case 14, and more particularly to the flange 28 adjacent the top portion 16 of the chamber 12.
  • the vent passage 62 also has a second portion 74 which communicates the first portion 68 with the interior passage 32 of the guide tube structure 30.
  • the first portion 68 is a bore in the flange 28 and the second portion 74 is a passage formed in the block 70.
  • the guide tube structure 30 in the embodiment illustrated, includes a first tube 76 which includes the upper end portion 36 and a second tube 78 which includes the lower end portion 38, of the guide tube structure 30.
  • the guide tube structure 30 also includes a first passageway 80 through the case 14, and more particularly through the flange 28, and a second passageway 82 through the block 70 with the first and second passageways 80 and 82 connecting the first tube 76 to the second tube 78.
  • a block 70' is utilized which is of a somewhat different nature than the block 70 of the embodiment of Figures 1-3.
  • the block 70' has a second passage portion 74' which communicates a passage portion 68' with the interior 32' of the guide tube structure 30'.
  • the block 70' has a boss 90 attached thereto and generally integral therewith with the boss 90 having a central bore 92.
  • the guide tube structure 30' is connected to the bore 92 and the second passage portion 74' intersects bore 92 leading to the interior 32' .
  • the embodiment of Figure 4 is particularly useful in situations wherein the lower end of the guide tube structure 30' measures the oil level in a pan (not illustrated) which sits below the chamber 12. In such a construction, the dip stick guide tube structure 30' cannot conveniently be directly routed through the transmission case. It should be noted that the upper ends of the filler tube structure 20' and the guide tube structure 30' are arranged just as are the upper ends of the filler tube structure 20 and the dip stick tube structure 30 as shown in Figure 1. Thus, hydraulic lock, on filling, is prevented.
  • Apparatus as set out above is particularly useful for adding liquid to a closed transmission system of an earthworking vehicle.
  • the proper dip stick for checking the fluid level in a chamber is immediately available to servicing personnel.
  • air venting is provided via the interior of the dip stick guide tube during filling of the enclosed chamber.

Abstract

Le personnel d'entretien peut confondre des jauges de niveau dans des vehicules qui possedent plusieurs reservoirs de fluide. Lorsque de l'air est emprisonne a l'interieur des reservoirs pendant le remplissage il peut se produire un verrouillage hydraulique. La structure du tube de remplissage (20) et la structure du tube de la jauge de niveau (30) de la presente invention ont leurs extremites superieures maintenues dans une adaptation tubulaire (40) qui est recouverte par un bouchon (58). Ceci elimine toute possibilite de confusion quant a savoir quelle structure de tube de jauge de niveau (30) correspond a un reservoir ou chambre particuliere (12). Dans le mode preferentiel de realisation la mise a l'event de la chambre (12) dans laquelle on introduit le fluide s'effectue via un passage interieur (32) de la structure de tube (30) de la jauge de niveau, eliminant ainsi le verrouillage hydraulique.
