11. The engine uses a single displacer to reduce moving parts and uses high energy acoustics to transfer energy. 12. Each displacer unit contains a rubber spring, and damping is achieved by the displaced fluid passing through rubber valves. 13. The piston also is linked to a displacer that moves the hot air to the opposite, cooler end of the cylinder. 14. The "'Ringbom engine "'concept published in 1907 has no rotary mechanism or linkage for the displacer . 15. This is instead driven by a small auxiliary piston, usually a thick displacer rod, with the movement limited by stops. 16. The displaced fluid passes to the displacer of the paired wheel, thus providing a dynamic interaction between front and rear wheels. 17. It contains a working gas ( often air ), and either two liquid pistons or one liquid piston and a displacer . 18. In 1979 he published the book " Displacer y Transendencia en el Arte " ( Displeasure and transcendence in Art ). 19. The cold head consists of a two-stage cold head cylinder ( part of the vacuum vessel ) and a drive unit displacer assembly. 20. The power piston in the displacer type stirling engine, is tightly sealed and is controlled to move up and down as the gas inside expands.
