ABSTRACT:
The invention relates to a power control system for a hot gas engine in which the power depends on the mean working gas pressure in the engine. Said engine is of the type having an even number of working gas charges separated by pistons each having two axially displaced piston rings. Said piston rings and their piston ring grooves are shaped to act as check valves and so that in each other piston the space between the piston rings will contain gas of maximum working cycle pressure whereas in the remaining pistons it will be minimum working cycle pressure.
