Definitions

  • This invention relates to fuel oil flow controls, in particular for controlling the flow of fuel oil to the pot-type burner of a domestic space heater.
  • an oil flow control device comprising a housing defining therein a chamber for containing oil and having an outlet, a metering disc having a plurality of metering apertures therein, the metering disc being movable to bring any selected one of its apertures into register with the outlet.
  • the apertures are of different sizes in order to vary the flow rate, and the disc is located by a ratchet device.
  • the present invention consists of the provision of a cleaning device mounted within the housing of the oil control and movable into engagement with said openings to dislodge dirt particles therefrom.
  • FIG. I is a section in a vertical plane through an oil flow control device according to the invention, and showing one form of cleaning device.
  • FIG. 2 is an end elevation, part sectioned, of the con trol device of FIG. 1, showing an alternative or addi tional form of cleaning device.
  • control device comprises a housing defining therein a chamber 11 for containing oil, the chamber having an oil inlet 12 and an inlet valve 13 controlled by a float 14 to maintain a constant level of oil within the chamber.
  • An outlet orifice I5 is formed in the base of the chamber, and flow through the outlet orifice is metered by a metering disc 16 keyed to a vertical shaft 17, the latter being rotatable by a knob 18 in the cover 20 of the housing.
  • the disc 16 contains perforations 16a disposed around a circle about the axis of the shaft, and each of the metering apertures formed by the perforations can be brought into register with the outlet orifice by rotation of the shafts into any one of a corresponding number of positions which are located by a ratchet device 21.
  • the disc is biased into engagement with the outlet orifice by a spring 22.
  • the cleaner is in the form of a pricker pin 23 disposed parallel to the disc shaft and movable manually against the force of a return leaf spring 24, by a push button 25 or the like in the cover of the housing.
  • the pricker pin is located with its point directed towards the circular path of movement of the disc apertures so that when the disc is brought to rest by its ratchet device the pin will be directly opposite one of the metering apertures.
  • the pin is located, as shown, on the axis of the outlet orifice to act on the aperture through which the oil is currently being metered.
  • the cleaning device takes the form of a brush 26 supported in a wall of the housing above the disc and held in permanent sliding engagement with the disc.
  • the brush is located diametrically opposite the outlet orifice so that the disc will be biased by spring 22 into engagement with the brush 26 with a force approximately balancing that between the disc and the outlet orifice. If, therefore, an aperture of the disc becomes clogged with dirt, it is necessary merely to rotate the vertical shaft on which the disc is mounted to bring each of the apertures, in turn, into engagement with the brush.
  • the brush is located in a recess in the base of the housing, and preferably this recess is inclined in such a way that the bristles are inclined to the surface of the disc. As a result, rotation of the disc in one direction will cause the bristles to sweep over the apertures, but rotation in the opposite direction will tend to force the bristles into the apertures and push dirt through the apertures.
  • the cleaning brush can be additional to, or alternative to, the pricker pin.
  • An oil flow control device comprising a housing defining therein a chamber for containing oil and having an outlet,
  • a metering disc having a plurality of apertures therein, the metering disc being movable to bring any selected one of its apertures into register with the outlet, and
  • a brush mounted within the housing separate from the orifice in engagement with said metering disc and said apertures in the disc as the disc is moved whereby dirt particles are dislodged from the apertures by the brush.
