Fluidic-piston engine

摘要

An external combustion engine includes: a plurality of cavities; a compressible working fluid in fluid communication between each pair of adjacent cavities; and a plurality of hydraulic linkages in reciprocal phase communication between each pair of alternate cavities. In an alternative embodiment the external combustion engine includes: a plurality of cavities; a compressible working fluid in fluid communication between each pair of adjacent cavities; and a plurality of articulated mechanical linkages in reciprocal phase communication between each pair of alternate cavities. In another alternative embodiment the external combustion engine includes: at least four upright cavities disposed substantially equidistant from a central upright axis; a compressible working fluid in fluid communication between each pair of adjacent cavities; and at least one linkage in reciprocal phase communication between each pair of alternate cavities. The at least one linkage may comprise a hydraulic linkage. Alternatively, the at least one linkage may comprise an articulated mechanical linkage.
