Abstract

114,479. Cory, F. G. April 5, 1917. Worm fans; casings; regulating.- In a pump applicable as a fuel pump for internal-combustion turbines of the kind described in Specification 105,384, a helical or helicoidal blade e, e<1> revolves in a conical casing, the fluid being delivered at the small end f, which forms a pressure-equalizing space owing to the blade being stopped short of that end. The pitch of the blade decreases towards the exit end. An air inlet m and a liquid or gaseous fuel inlet i are fitted to the larger end of the casing. A revoluble plate n is fitted on the air inlet so that the suction on the fuel inlet may be increased. A plate l may be fixed on the blade e to cover, during part of the revolution, the air inlet, which may be separated from the fuel inlet. Fig 3 shows a fuel inlet i<1> with a flared end and a guard-plate k for preventing the entry of lubricant to the air inlet.
