Abstract
To adapt a compressor valve to varying operational conditions of the compressor, particularly to varying numbers of revolutions and/or the respective specific weight of the transported gas, a process and a compressor valve for executing the process are provided. The process is that a compressor drive at various numbers of revolutions or transporting gas with varying specific weight, the spring force--possibly resulting from several spring forces--acting during operation on the plug in a closing direction and/or the lift of the plug is forcefully reduced with falling number of revolutions or increasing specific weight the process is reversed either continuously or in steps. In the compressor valve at least some of the closing springs are braced against a spring plate which is arranged on the outside of the catch in the lift direction of the plug, adjustable either continuously or in steps, or it is the catch itself which is continuously or in steps adjustable in the lift direction of the plug, relative to the valve seat.
