DISPLACEMENT-TYPE SPHERICAL ROTARY MACHINE Russian patent published in 2000 - IPC

FIELD: displacement machines such as engine, pump, or compressor. SUBSTANCE: machine casing is built up of two sections 1 and 2. Spherical space of casing accommodates central rotor 4 coupled on each side to respective sector rotor 5, 6 through diametral joint. Rotors 4, 5, 6 form working chambers 9, 10, 11, 12. Diametral joint of sector rotor 6 has two half-axles 15, 16 mounted on its projections and locked in position by means of fastenings. Journals of half- axles 15, 16 are located in bores of central rotor 4 inside meniscus 19. Sector rotor 6 has spherical cavity whose shape follows that of meniscus 19. Diametral joint of sector rotor 5 may be provided with solid cylindrical axle and may incorporate meniscus like joint of rotor 6. Sector rotors 5, 6 are provided with set of through ducts 20 through 25 for lubricating and cooling machine parts. EFFECT: increased speed and facilitated assembly procedure of rotor. 10 cl, 3 dwg
