Definitions

  • This invention relates to a suction system arrangement in a motor vehicle tank which enables tank base deformation to be absorbed.
  • the fuel pump is positioned within a calming chamber and is connected to it via elastic antivibration elements.
  • the calming chamber rests on the tank base and consequently moves as a result of variations in the tank height due to deformation caused by pressure in its interior and the weight of the fuel.
  • the fuel pump moves with the calming chamber and its distance from the base remains constant, allowing all the fuel contained in the tank to be drawn in, independently of its deformation.
  • the object of the present invention is to provide a new arrangement of the suction system, and in particular of the pump, which by overcoming the aforesaid drawbacks enables complete intake to be achieved in all cases independently of the deformation of the tank base.
  • a suction system arrangement in a motor vehicle tank comprising a pump connected to a filter located in proximity to the tank base within a calming chamber, characterised in that said filter and said pump are connected together by a variable-length conduit.
  • said pump is connected to said tank by elastic conduit elements.
  • FIG. 1 schematically shows a suction system arrangement according to the invention within a tank, partially shown by its base 10.
  • the arrangement comprises a pump 11 connected to a filter 12 located in proximity to the tank base 10 within a calming chamber 13.
  • the pump 11 is connected via a first port 14, inserted into an elastic conduit element 15, to the tank roof 16.
  • the second end of the conduit element 15 is mounted on a pipe piece 17 extending from the tank roof 16 and connected to the fuel delivery pipe, partially shown schematically at 18.
  • the conduit element 15 is clamped at its two ends to the pipe piece 17 and to the pump port 14 by fixing collars 19.
  • variable-length conduit consists of a tubular bellows element 21, a first end 22 of which is fixed to the second pump port 20 by a fixing collar 19.
  • the second end 23 of the tubular bellows element 21 is mounted over a pipe piece 24 emerging from the filter 12 and is clamped by a further fixing collar 19.
  • those ends 22 and 23 of the tubular bellows element 21 used for the fixing are provided with a radially outward projecting flange 25 in the region in which the bellows portion commences.
  • These mutually opposite flanges 25 are used for locating the opposing ends of an elastic element 26, such as a compression spring, which acts to force apart the parts against which it abuts, ie it tends to maintain the bellows in its extended position.
  • Figure 2 shows a second embodiment of a suction system arrangement according to the invention in which the same reference numerals are used for identical elements.
  • the second port 20 of the pump 11 is connected to the pipe piece 24 emerging from the filter 12 by a different type of variable-length conduit.
  • variable-length conduit consists in this embodiment of a pair of telescopic tubular elements 27 and 28, of which the outwardly facing ends are also fixed to the second port 20 of the pump 11 and to the filter pipe piece 24 by fixing collars 19.
  • an elastic element 26 such as a compression spring, which acts to force apart the parts against which it abuts, ie to maintain the elements in its extended position.
  • the pump 11 is fixed to the roof 16 by the conduit element 15 which can consist of a rubber tube acting as the antivibration element and the passage for the fuel leaving the pump.
  • the conduit element 15 can consist of a rubber tube acting as the antivibration element and the passage for the fuel leaving the pump.
  • the distance of the pump port from the tank base varies in accordance with the deformation of the tank base.
  • the arrangement according to the present invention consisting of mounting on the suction port 20 of the pump 11 an extendable element such as the tubular bellows element 21 or the pair of tubular telescopic elements 27 and 28, solves the problem of correctly positioning the filter 12 on the base independently of tank deformation.
  • the possible presence of the spring 26 ensures constant adherence of the filter 12 to the inside of the base of the calming chamber 13, ie on the tank base 10.
  • both the tubular bellows element 21 and the pair of tubular telescopic elements 27 and 28 can be formed either rigid or integral with the filter pipe piece 24 .
