Stirling engine of double-head piston and swash plate type - has cylinder block with front and rear working gas chambers, surrounded by heat exchangers

摘要

The engine has a cylinder block (4,5) with a heat insulator (1), a central bore, surrounding bores (6a-6d), and a swash plate chamber (7). The cylinder block has front and rear housing sections (10,11), and a shaft (12) in the central bore. The swash plate (13) is fixed to the shaft, and rotates in the chamber. Double-head pistons (15a-15d) are in active connection to the swash plate via shoes (14) and move in the cylinder block bores. Front (Fc) and rear spaces (Ra) contain a working gas. A heat exchanger (16,17) extends around front and rear spaces. Connection pipes (20a-20d) couple the spaces and a heat accumulator. ADVANTAGE - Simple design and increased strength.
