FIELD: engine devices and pumps.
SUBSTANCE: toroidal working cylinder is divided into working chambers by pairs of elements, each consisting of a blade (piston) and a lock chamber, and the movement mechanism of the lock chamber allows unobstructed controlled movement of the blade (piston) and gas mixture along the cylinder while maintaining compression and the composition of the compressed gas mixture. The rotating annular element, designed as a side wall of the cylinder, provides both kinematic and power connection between the piston and the output shaft, acting as an engine rotor.
EFFECT: simplicity of the design, which excludes mechanisms for coordinating the motion of the blades and power take-off, valve and crank-conrod mechanisms and not providing blade retainers, makes it possible to significantly simplify the engine, increase its reliability and reduce the requirements to the used materials, and, as a result, its cost.
