摘要： A gas compressor for vehicle braking systems controlled by compressed air can be operated under load or in idle operation. In idle operation, no compressed air is produced. In operation under load, the gas compressor produces compressed air as required by the pressure medium installation. During prolonged operation of the gas compressor at a relatively high operating speed, for example, during travel on super-highways, the power consumption can be decreased and thereby also the production amount of the gas compressor, without having to switch the gas compressor over into idle operation. A clearance volume of less volume than the nominal volume of the gas compressor is provided which can be connected via a valve to the compression chamber of the gas compressor, thereby making it possible to enlarge the compression volume. In addition, a process for the control of the auxiliary valve takes into account different operating magnitudes of the gas compressor and other elements of the vehicle.
