Abstract
A compressor, especially for compressing the fuel gas for a gas turbine, is controlled by a throttling member (,) arranged on the intake side of the compressor as a function of the gas consumption of the user (,) such that the flow cross section is reduced during a reduction in gas consumption. The intake-side throttling member may be additionally controlled as a function of the pressure on the intake side of the compressor. Additional control circuits, especially an end pressure controller (,), which maintains the end pressure by acting on the guide vanes or on the speed of rotation of the compressor, and/or a pump surge limiter (,), which acts on a blow-by valve (,) connecting the outlet side to the intake side of the compressor (,), may be additionally present.
