Rotary-vane mechanism for engines and compressors

A rotary-vane mechanism, comprising:

• a rotor and a casing, wherein the rotor comprises a drive shaft and at least one vane;
• the casing having a quasi-cylindrical tubular shell or a quasi-spherical shell and support walls that support the drive shaft and wherein the rotor is mounted within the casing;
• the drive shaft extending outward from the casing, wherein the drive shaft touches the inner surface of the casing in at least one contact location, wherein the at least one contact location is provided by a sealing plate;
• the casing including intake ports, exhaust ports, ports for an ignition mechanism, wherein the intake ports are provided with one-way valves;
• the drive shaft comprising at least one guide slot which penetrates through the drive shaft wherein the at least one vane is located inside the at least one guide slot, wherein edges of the at least one vane constantly touches the inner surface of the casing during a rotor rotation of the rotor;
• the at least one vane having a rectangular shape or a discoid shape, wherein at least one sealing plate or at least one sealing ring is located along an edge of the at least one vane;
• and
• the rotor and the casing forming isolated spaces inside the rotary-vane mechanism and during the rotor rotation provides three work strokes for an engine, and two strokes for a compressor.
