Abstract (en)
[origin: WO2007147789A1] The invention relates to a free-piston device comprising at least one piston cavity, in which at least one piston unit is mounted so that it can be displaced linearly. The piston unit or units can be driven by the action of a medium that expands in an expansion chamber. The piston cavity or cavities has/have a resilient-action chamber, which contains a compressible gas for exerting a restoring force on the piston unit or units and on which an actuator for controlling and/or regulating the restoring force during the operation of the free-piston device is mounted. The invention also relates to a method for operating a free-piston device.
