Expander stroke delay mechanism for split stirling cryogenic cooler

摘要

This invention comprises a cryogenic cooling device operating in the manner of a split Stirling cycle engine whereby a sinusoidal pressure-wave generator distal to a regenerator displacer piston and accompanying cylinder, individually compresses in a delayed manner and expands a contained volume of gas in an expander housing respective to regenerator displacer piston travel to bring about a cooling effect in an attached displacer housing.
