A pneumatic engine of rotary type includes body with chamber in cylindrical form, rotor with flywheel and rollers eccentrically fixed on it, placed coaxially in the chamber, working chambers formed with placed closely tabs placed in the circular borings of the body and sections of the chamber placed between those tabs and the ring placed eccentrically in the chamber between its cylindrical surface and flywheel with rollers, cover connected to the body and arranged with possibility of supply of working mix to the chamber formed with the inner surface of the ring, and to the working chambers, and slide fixed on the shaft of the rotor with possibility of supply of working mix synchronously with rotation of the rotor. The tabs are arranged as a truncated hollow cylinder with bottom and include axles for interaction with the elements for pressing tabs, the body includes openings for placement of axles of the tabs and openings for discharge of working mix from the chamber, and the circular borings are arranged radially with respect to the long axis of the chamber. The axles of the tabs are made hollow. The elements for tab pressing include twisted torsion springs fixed inside the axles of the tabs with possibility of simultaneous pressing of those ends to the outer surface of the ring, and the bottoms to the surface of the cover adjoining those. |
