Abstract

727,333. Surface carburetters. WOOD, A. R., WOOD N. R., and FANNING, F. E. Oct. 22, 1952 [Oct. 22, 1951], No. 26499/52. Class 7(3). A carburetter comprises an aeration chamber, means for controlling the level of liquid fuel in the aeration chamber, a first series of aeration tubes supported on a central column within the aeration chamber the tubes leading from the outside of the aeration chamber and each terminating in an arcuate portion provided with a series of small holes adapted to lie on the floor of the aeration chamber, a second series of aeration tubes each having a series of small holes in the lower end and suspended about and communicating with the interior of the central column which is connected to the outside of the aeration chamber and, third, air inlet means positioned in the upper part of the aeration chamber between the liquid fuel level and the outlet. As shown fuel is maintained at the level 29 in the lower part of a chamber 19 by means of two float controlled valves 18, 63. Air is drawn in by the engine suction through an air cleaner not shown into tubes 66-70 which terminate in perforated arcuate portions below the level of the fuel. This air produces a foam in the lower part of the chamber. Additional air from the air cleaner enters through a tube 105 and passes into tubes 92-96 which comprise perforations 99 slightly larger than those in the other tubes. These perforations face approximately the centre of the chamber and are arranged so that jets of air issuing from adjacent holes cross one another. Further additional air enters through calibrated holes 109. In its path to the engine the fuel air mixture passes through holes 118 covered by a filter gauze 115 into a chamber 33. At higher speeds a valve 126 opens under the effect of suction and admits yet another supply of additional air. On leaving the chamber 33 the mixture passes a non-return valve 130 and a plate 136A having ports not shown. It then leaves by way of a tube 139 and connection 140 having connecting faces 141, 142 to which the engine inlet manifold is attached. A butterfly valve is located within the connection 140. A back fire valve relief valve (not shown) is fitted to the chamber 33. A ring 54 is carried by lugs 48-52 (Fig. 5) and a central pillar 55 is secured by lugs 56.
