Abstract
A combustion apparatus 2 has a fuel spraying nozzle 12, a feed canal 16 and a return canal 17, both the canals connected to the nozzle, with the former canal 16 feeding a fuel to the nozzle and with the later canal 17 allowing an unsprayed portion of the fuel to flow back. An electro-magnetic pump 18 disposed in the feed canal 16 serves to compress the fuel towards the nozzle 12, and an injector valve 25 is disposed in the return canal 17. A low rate at which the fuel is sprayed out from the nozzle is controlled by a controlling means 40 by regulating the mode of opening and closing the valve body 33 of injector valve 25.
