Abstract
630,792. Cooling bearings. DE HAVILLAND ENGINE CO., Ltd., HALFORD, F. B., and DOWNES, D. G. Nov. 20, 1946, No. 34402. [Class 12 (i)] Cooling of a bearing of the rotor of a combustion - turbine apparatus for aircraft is effected by the flow of liquid fuel which either passes directly to a chamber surrounding the bearing or alternatively such chamber is fed with an auxiliary fluid flowing in heat-exchanging relationship with the liquid fuel. As shown in Fig. 5, fuel from a tank A is delivered by a low-pressure pump B through a filter C to a chamber D having a byepass thermostaticallycontrolled from the bearing, so that fuel passes either through pipe F3 to the cooling chamber of bearing G, or through pipe E to a high-pressure pump B<SP>1</SP>, pilot's control device L and manifold M feeding the burners M<SP>1</SP> in the combustion chambers N. The fuel to pipe F<SP>3</SP> may be cooled by passing through an annular passage K<SP>1</SP>, K<SP>2</SP> formed in the compressor intake. Some of the fuel delivered from the bearing may be returned to tank A to prevent freezing. In a modification, Fig. 6, fuel from chamber D<SP>1</SP> enters a pipe F and a heatexchanger W through which circulates an auxiliary liquid in a closed circuit which contains the bearing G and a pump V<SP>2</SP>, the liquid being non-inflammable, such as water or oil and being cooled by the fuel passing through the heat-exchanger W. The turbine J, Fig. 4, has a tubular shaft H<SP>1</SP> with a spaced sleeve H<SP>2</SP> which is mounted in a bearing O in a housing P provided with safety bearing surfaces P<SP>1</SP>, P<SP>2</SP>, P<SP>3</SP>. The housing P is mounted in a retainer Q and between them an annular chamber R is formed, surrounding the bearing O, the chamber having inlet and outlet pipes F<SP>4</SP>, F<SP>5</SP> for the fuel. The retainer Q may have a chamber or muff S supplied through a pipe S<SP>1</SP> with air drawn from pipe T which delivers air to cool the interior of the bearing and the face of the turbine rotor J. Chamber R has packing compressed by a nut Q<SP>4</SP>. Specification 578,765 is referred to.
