Abstract (en)
[origin: WO2013017669A1] A compressor device and a cooling device fitted therewith and a cooler unit fitted therewith are provided, which unlike known compressor arrangements with a rotary valve, operates with lower losses. The combination of a compressor arrangement, in which a working medium is periodically compressed by a reciprocating compressor element and then expanded again, with a drive arrangement mechanically coupled to the compressor element, allows the compressed gas to be provided within the frequency range required for Gifford-McMahon coolers and pulse-tube coolers. The electro-hydrostatic drive arrangement and the compressor element are coupled by a mechanical or a magnetic coupling. This eliminates the need to use high-loss generating rotary valves. The combination of simple controllability of an electric motor and the force of a hydraulic mechanism can be applied to build an extremely efficient compressor which, due to the absence of a rotary valve when using with Gifford-McMahon coolers or pulse-tube coolers, results in considerably lower losses. A highly-efficient compressor arrangement is thus provided.
