Abstract

A piston engine has a housing and a piston. The piston is magnetically and movably disposed in the housing. A device for magnetically supporting the piston is fixedly mounted relative to the housing. A linear machine in conjunction with the magnetic bearing of the piston can prevent friction and thus result in a machine for converting mechanical into electric energy without having to lubricate and with reduced mechanical effort.
