An energy converter comprising a free piston engine with a cylinder (2), a piston (3), a body connected to the piston such as an armature (11) of a linear electric generator (10). The energy converter comprises a spring device (15), via which the armature (11) is springingly connected to the housing (1), and which is arranged to permit an oscillation of the armature (11) in the piston's (3) direction of movement with a natural frequency f, relative to the stator (12). |
