A trochilic piston engine. A plurality of trochilic pistons rotate about the cylindrical axis of an engine chamber. Each piston presents a pressure-bearing surface against which expanding gases exert a pressure tending to push the pressure-bearing surfaces of adjacent pistons, and therefore the adjacent pistons, apart. The engine includes a gear train comprising a fixed sun gear about which planetary gears associated with each piston revolve, the planetary gears being connected to an assembly for turning a drive-shaft. The pistons are connected to their respective planetary gears through respective crank arms having a sliding member coupled to an eccentrically disposed projection of the respective planetary gear. As the pistons rotate about the pivot point, the leverage that adjacent pistons exert on the respective eccentrically disposed projections varies in opposition over an engine cycle; however, the pistons are constrained to rotate in the same direction by the gear train.
