Abstract
A closed working fluid system for a regenerative type Stirling engine is disclosed. The system has pistons therein arranged to be of the double-acting type. A compensating system is employed to eliminate the force differential that works upon the upper and lower surfaces of each double-acting piston during cold engine start and restarting conditions. The compensating system employs a parallel path to the normal intercommunication between hot and cold chambers; a variable area valve is disposed in the parallel path. Communication through the variable area valve is controlled by a shuttle valve and one-way flow is assured by at least one check valve.
