  • High-pressure compressor and its use and method for operating it
    Patent number: 8231357
    Abstract: A high-pressure compressor (1) for compressing gases, which has at least two working spaces (3, 3?) and is optionally adjustable between a single-stage operating position, in which the gas to be compressed is compressed in one single stage, and a multi-stage operating position, in which at least one working space (3?) is connected in series with at least one further working space (3), wherein at least three working spaces (3, 3?) are provided which all have the same working volume.
