Oil-free piston compressors

Abstract

This thesis describes the development on long lifetime and an efficient piston compressor operating in a clean environment where oil lubrication must be excluded. No oil lubricant and tight piston/cylinder fit leads to higher demands with respect to design specifications. The engineer is often confronted with various effects that occur during operation, e.g. tribology, material deformation, heat transfer, fluid flow. An accurate prediction of those processes is important to be able to analyze any newly invented design.
