Abstract (en)

[origin: US4789298A] The method and apparatus for controlling the operation of a turbocompressor which has a suction and a discharge with a blow-off valve for regulating the performance thereof includes a sensor in the suction and discharge for sensing an operating condition such as pressure and temperature which is connected to deliver to a comparator a performance signal for the control of the blow-off valve. The control signal which is delivered to the comparator is modified in accordance with a memory which includes a blow-off curve gradient which effects the amplification of the signal which is sent to a controller in accordance with the blow-off conditions which are to be set in motion on the basis of the performance characteristics which have been sensed.
