Abstract
A process and apparatus for controlling flow of fuel in a gas turbine has a fuel control unit which comprises piston pumps which have at least two piston elements working in opposite phase to one another, and which can be operated in opposite phase, so that the flow of fuel to the injector nozzle is sufficiently constant. This constancy of the fuel flow is thereby a function of the delivery frequency and the number of pump piston elements operating in parallel.
