Abstract
Free piston assembly, comprising at least one piston accommodating device, at least one piston device having a first piston surface and a second piston surface facing away from the first piston surface, which is moveable in a linear manner in the corresponding piston accommodating device, and an expansion space which is arranged in the piston accommodating device and delimited by the first piston surface, wherein the piston device is arranged to be driven by the action of a medium which expands in the expansion space, wherein a resilience space arranged in the at least one piston accommodating device is delimited by the second piston surface, and wherein the resilience space is connected to at least one pre-compression chamber in fluidic manner.
