Six-stroke rotary-vane internal combustion engine with hermetically sealed working space

Abstract

The invention relates to a six-stroke rotary-vane internal combustion engine with hermetically sealed working space comprising a stator with at least one inlet and at least one outlet, a respective hole for at least one spark plug, and working chambers comprising of an air-fuel intake and compression, and of expansion and exhaust of combustion products working chamber; a cylindrical rotor rigidly fastened to a shaft with combustion chambers alternating with vane grooves made in the cylindrical surface and vanes fitted in the vane grooves; side walls; front and rear bearing shields. The whole working space of the engine is bound by parts rigidly and hermetically fastened to the stator. Composite prismatic pieces are placed into end grooves on both sides of the rotor, while the ends of said composite prismatic pieces are pushed by a first spring against the adjacent vanes and one of the longer sides of the composite prismatic pieces is pushed by a second spring against the side walls.
