Definitions

  • the invention involves a liquid separation device that is particularly, but not exclusively, applicable to vehicle fuel systems for the removal of water from the fuel.
  • the device has a lower inlet chamber and an upper outlet chamber separated by a partition having a valve that can be closed by a float body in the lower chamber as water accumulates there.
  • a valve that can be closed by a float body in the lower chamber as water accumulates there.
  • This invention relates to devices for the separation of heavier and lighter fractions from a mixture of liquids.
  • a liquid separator for separating heavier and lighter fractions of a mixture of liquids, comprising a container having upper and lower chambers separated by a valved partition, said lower chamber forming a liquid entry and settling region and having a drain outlet for the heavier fraction, the upper chamber having an outlet for the separated lighter fraction drawn through the valve, a float body of the valve disposed in the lower chamber having a density between those of the lighter and heavier fractions.
  • external bleed means are provided whereby the upper and lower chambers may be brought into communication again after closure of the valve since continued use of the apparatus to which the lighter fraction is drawn may result in a partial vacuum being created in the upper chamber, this tending to keep the valve closed.
  • external indication means are provided to give a warning signal when the valve closes.
  • Such means may, for example, comprise a diaphragm actuator controlling an electrical alarm circuit and operable by a pressure drop in the upper chamber after closure of the valve.
  • FIG. 1 shows one form of separator according to the invention in sectional elevation
  • FIG. 2 shows the separator in the fuel supply to a diesel engine.
  • the separator comprises a container having upper and lower sections 2, 4 which form respective chambers 6, 8.
  • the sections 2, 4 are secured to a central separating valve plate having a frusto-conical seating 12 for an O-ring 14 of a float valve body 16 which is laterally supported by boss 18 in the plate by a stem 20 projecting through the boss.
  • the lower chamber 8 has an inlet connection 22 and has a relatively large internal volume so that it can act as a settling region for the heavier fraction of a mixture 3,386,581 Patented June 4, 1968 and if desired, a drain point 24 is provided at the bottom of the chamber with a manual valve 25 for removal of the collected heavier fraction from time to time.
  • the lighter fraction after passing through the valve plate 10, leaves the upper chamber 6 through outlet 26.
  • the float valve body 16 is denser than the lighter fraction but can be floated by the heavier fraction. As the heavier fraction collects in the lower chamber, the body therefore rises and the valve is closed before the heavier fraction can escape into the upper chamber. At this stage, there is an interruption in the further supply of the lighter fraction from the outlet of the device; continued use of the lighter fraction at its point of final delivery will now cause a pressure drop in the upper chamber drawing the valve more tightly against its seating and this pressure drop is employed to operate a warning signal.
  • the means for generating this signal comprise a diaphragm 28 forming a top closure of the upper chamber and normally held in an upper position by a spring 30.
  • the circuit indicated purely diagrammatically, to which the contacts are connected may be arranged to operate a visual and/or audible warning device 37.
  • a diesel engine 50 has its injector unit '52 receiving a fuel supply from a tank 54 through a sep arator 56 constructed in the manner detailed with reference to FIG. 1, a filter 58 and a pump 60, the outlet valve 25 of the separator being below the level of base 54a of the fuel tank. In certain instances, it may in fact be preferred to fit the separator in the fuel tank.
  • the separator as described above has particular application in the separation of water from an oil fuel, e.g.,
  • warning signal can be transmitted to some point such as the drivers cabin.
  • a further feature of the device in dealing with fuel oil/ water mixtures is that as the depth of water increases in the lower chamber, so does the efliciency of separation of sediment from the fuel.
  • a liquid separator for separating heavy and lighter constituents of a mixture comprising, in combination,
  • valve member adjacent said aperture being upwardly displaceable to close the aperture, said lower chamber forming a liquid entry and settling region and a drain outlet for the heavier liquid being located in its bottom portion while an outlet for the separated lighter fluid flowing through the valve aperture is provided in the upper chamber,
  • a float body being disposed in the lower chamber and having a density between those of the heavier and lighter liquids whereby accumulation of the heavier liquids in the lower chamber will cause the float to rise and to close the valve at the partition, there being further provided an electrical actuator comprising a pressure-sensitive member in the upper chamber and circuit closure means associated with said member and a warning device operable by said actuator, said member being displaceable by a pressure drop in the upper chamber after closure of the valve to actuate the circuit for the remote operation of the warning device, and
  • externally operable means being provided on the container for displacement after a partial vacuum has been established in the upper chamber to cause the opening of the valve against a closure force exerted by said vacuum.
  • a separator according to claim .1 wherein the float body is transversely supported relative to the partition; a sealing ring of the valve being mounted on the body and a seating at the partition being arranged to cooperate with said sealing ring for closure of the valve.
  • a separator for separating heavier and lighter constituents of a mixture comprising, in combination, a container, upper and lower chambers within said container, an internal partition separating said chambers and a valve aperture in said partition permitting communication between the chambers, a valve member adjacent said aperture being upwardly displaceable to close the aperture, said lower chamber forming a liquid entry and settling region and a drain outlet for the heavier liquid being located in its bottom portion while an outlet for the separated lighter liquid flowing through the valve aperture is provided in the upper chamber, a float body being disposed in the lower chamber and having a density between those of the heavier and lighter liquids whereby accumulation of the heavier liquid in the lower chamber will cause the float to rise and to close the valve at the partition, there being further provided an electrical actuator comprising a pressure-sensitive member in the upper chamber and circuit closure means associated with said member and a warning device operable by said actuator, said member being displaceable by a pressure drop in the upper chamber after closure of the valve to actuate the circuit for the remote operation of the warning device and externally operable
