ABSTRACT:
The amount of fuel supplied by a low pressure pump and a high pressure pump to combustion means is controlled by a control unit. If most of the fuel delivered by the pumps is required by the engine a clutch engages to provide a direct mechanical drive between the pumps so that they are driven at the same speed. However if the combustion equipment requires a reduced flow of fuel the clutch disengages and the excess fuel is diverted by a valve to a turbine. The turbine drives the low pressure pump at a higher speed than the speed of the high pressure pump. The energy of the diverted fuel is converted to mechanical energy to drive the turbine so that the temperature rise of the diverted fuel is reduced.
