Piston engine having magnetic piston bearing

Abstract

The present invention relates to a piston engine (1). Said engine comprises a housing (2) and a piston (3). The piston (3) is magnetically and movably disposed in the housing (2). A device (7) for magnetically supporting the piston (3) is fixedly mounted relative to the housing (2). A linear machine (15) in conjunction with the magnetic bearing of the piston (3) can prevent friction and thus result in a machine for converting mechanical into electric energy without having to lubricate and with reduced mechanical effort.

Description

technical field [0001] The invention relates to a piston machine comprising at least one first piston and at least one first housing. The at least one first housing completely or at least partially surrounds the at least one first piston. The at least one first piston is movably magnetically supported in the at least one first housing by means of at least one device for magnetically supporting the at least one first piston. Background technique [0002] Heat engines are used to convert chemical energy to mechanical energy, thermal energy to mechanical energy, and mechanical energy to thermal energy. An internal combustion engine as a heat engine converts chemical energy into mechanical energy, a Stirling engine as a heat engine converts thermal energy into mechanical energy, and a heat pump as a heat engine converts mechanical energy into thermal energy. One of the most frequently used heat engines is the piston machine, in which the mechanical energy of the piston is tran...

Problems solved by technology

In internal combustion engines, parts of the lubricating oil are always combusted together and this leads especially to a high environmental burden.

The lubricating oil is destroyed by contamination and by the forces exerted on the lubricating oil, thus causing high maintenance costs in lubricated machines due to the required replacement of the lubricating oil
