ABSTRACT:
A pressure relief system for a multi-cylinder heat engine, such as a multi-cylinder Stirling engine, having at least two essentially discrete working gas volumes which experience out of phase cyclical variations in pressure during operation of the engine, to reduce the likelihood of damage to the components of the engine in the event of severe pressure imbalance conditions developing within the engine. A spool positioned within a cavity in a housing has a closed position and an open position. In the event of a severe pressure imbalance condition, the spool is moved to the open position, the working gas volumes are allowed to communicate and the engine is unloaded.
