Definitions

  • a centrifugal separator for de -aerating liquid comprises a separator chamber, preferably in the form of alhollow body of revolution, means for Withdrawing airfrom the upper end of the separator chamber, and'for withdrawing de-aerated liquid from the lower end thereof, and meansfor supplying aerated liquid to the chamber comprising at least one inlet passage ar-' ranged with a substantial tangential component of direction, so as to impart rotary motionto the liquid within the chambenat least one of the walls of "the inlet passage being movable and being resiliently urged towardsv the opposite wall of the passage, so, as to restrict the crosssectional area of the passage'whenthe pressure of liquid inthe passage falls, and thus 'to tend to mairitaina high velocity of flow through the passage and consequent high rotary velocities in the chamber, even when the volumetric rate of flow through the passage falls.
  • the movable wall of the passage is consti tuted by a leaf spring, and the leaf spring is preferably pre-stressed with its end in close contact with the opposite wall' of the passage when there'is no flow through the passage.

  • the invention is particularly applicable therefore to fuel supply systems of internal combustionengines of the fuel injection type.

  • the centrifugal separator 14 as shown in more devt ail in Figures 2 and 3, corn'prises a generally cylindrical Y mainseparator chamber 26 closed at .its upper end by a plate 27 with a small central aperture 28, which communicates with an upper air separation chamber 29 arranged directly above the main chamber 26.
  • the upper partof the cylindricalside wall of the main chamber is 'curved inwards to form a part-spherical head 30, while Patented Mar. 24,1959
  • Each inlet passage is provided with a fixed wall and an opposite movable wall, the movable wall being constituted by the free end of a leaf spring'36.
  • Each leaf spring is formed with a length slightly less than a quarter of the circumference of the separator chamber and is secured or rigidly attached at one end to a fixed block 37 mounted adjacent the inner periphery of the annular inlet passageway.
  • each leaf spring 36 is pro-stressed into contact with the inner face of the next block 37, and the face of each block at the point where the free end of thenextadjacent spring contacts it, is approximately tangential to the inner wall of the separator chamber.
  • the leaf springs 36 may be tapered somewhat from their fixed to their free ends, and their resilience is arranged so as to maintain the pressure in the annular inlet passageway 35 at approximately 35 lbs/sq. in. above the pressure in the separator chamber 26.
  • the arrangement thus tends to maintain a substantial and approximately constant flow velocity through the throats of the inlet passages 38, and consequent high rotary velocities in the separator chamber, even when the volumetric rate of flow falls, due for example to increased fuel consumption by the injection pumps.
  • Make-up fuel for the circulatory system including the separator circulating pump 22, and fuel injection pumps 24, is supplied tothe main separator chamber 26 from the engine driven fuel delivery pump 12.
  • the make-up fuel is supplied to an annular make-up passageway 40 adjacent the upper end'of the separator chamber, and above the annular inlet passageway 35.
  • a series of circumferentially spaced make-up passages 13, which have a tangential component of direction, are provided in the wall of the separator chamber leading from the make-up passageway into the interior of the chamber in the part-spherical portion 30 of the side wall. The make-up fuel is thus caused to rotate with the main mass of fuel in the chamber 26 under the influence of the tangential streams issuing through the inlet passages 38.
  • the upper air separation chamber 29 is provided, as mentioned above, with an air escape port 20 at its upper end having an intake portion 20a opening into chamber 29.
  • the flow of air through port 20 is controlled by an air escape valve 41 which is actuated by a float 42 mounted within the chamber.
  • Both the main separator chamber 26 and the air separation chamber 29 are normally flooded under the pressure maintained by the fuel delivery pump 12, and air which is separated in the main chamber rises in the central core of the vortex through the central aperture 28 in the upper closure plate and separates out into the upper part 4 of the air separation chamber 29.
  • the air escape valve is opened and air is discharged through the air escape port 20 into the air vent line 18.
  • a cylindrical fine mesh filter screen 43 is provided in the upper chamber 29 surrounding the float 42 to exclude air bubbles from the annular space 44 surrounding the screen, and a series of passages 45 lead from this annular space downwards through the wall of the main separator chamber into vertical drillings 46 provided in the blocks 37 to which the leaf springs 36 are connected.
  • Each vertical drilling 46 communicates with one or more outlet drillings 47 which emerge at the inner tangential face of the respective block 37 adjacent the point. where the free tip of the next adjacent leaf spring 36 contacts this surface. This point is adjacent the throat of each inlet passage 38, and by venturi effect the reduced pressure at this throat thus draws the deaerated fuel from the air-separation chamber 29 into the streams of fuel issuing through the inlet passages 38.
  • the fuel supply system also includes a priming line 50 between the primary fuel filter 11 and the secondary fuel filter 23, and a pressure relief valve 51 in this priming line arranged to open when the pressure in the main supply line 10 reaches a predetermined value.
  • the engine driven circulating pump 22 is thus primed as soon as the pressure in the main supply line 10 reaches an appreciable value.

  • a centrifugal separator as claimed in claim 1 including an upper air-separation chamber, arranged above the main chamber, and means for returning the de-aerated liquid from the upper air-separation chamber to the main chamber comprising a passage leading from said air-separating chamber and emerging into said inlet passage at a point adjacent the throat thereof formed between said movable wall portion, and said fixed wall portion.
