Ringbom Stirling Engines
provides a highly technical treatment of the entire field of Ringbom free
displacer engines from the simple to the advanced and from small to large. First published in 1993 by Oxford
University Press, it has been newly reprinted in its complete original high
quality clothbound form. The book
contains a lengthy introductory chapter covering the development of all types
of Stirling engines with special emphasis on the mechanism problem. The second chapter describes the
original Ringbom patent and its recent simple modification which transformed it
into an engine capable of high speeds and rock-stable operation. For the mathematically inclined,
following chapters develop formulas for calculating the stable operating range,
phase angle, and power output of Ringboms. The book shows how to use this foundation to design Ringboms
to run on low or high temperature differentials and concludes with a chapter on
engine ideas for further exploration.
The book is well illustrated and contains material not readily available
elsewhere.
