Abstract

6081. Armstrong, Whitworth, & Co., Sir W. G., and Sodeau, W. H. March 13. Oil supply.-Relates to heating- apparatus as used in compressed-air plant, torpedoes, &c. for heating the air before it passes to a motor, in which the energy of the air is increased by burning therein liquid fuel. The fuel is supplied to the air proportionately to the kinetic energy of the air passing a given section of the pipe leading the air to the engine. In one arrangement, Fig. 1, a closed fuel tank a is connected to the combustion chamber by a pipe e and to a nozzle c pointing into an open cone piece d. In another arrangement, a Pitot tube h, which faces the current of air passing into the combustion chamber, is employed instead of the injector cone d. To increase the pressure on the fuel, a resistance may be placed between the Pitot tube h and the combustion chamber, or a reverse Pitot tube may spray the fuel into the chamber. In other arrangements, means, such as a cone m, aid the spraying of the fuel. In addition to the fuel chamber, a second chamber n, containing water, a solution of ammonia, salts, &c., may be connected to a Pitot tube and to the combustion chamber so as to mix water vapour &c. with the air or products of combustion. The supply pipe g from the reservoir n may be continued in the combustion chamber as a coil terminating in a spray nozzle so that the water &c. is heated before being sprayed.
