FIELD: engines and pumps.
SUBSTANCE: thermodynamic converter comprises case and rotor made up of wheel with spokes provided with vane guide channels and fitted on shaft. Rotor shaft consists of two parts rigidly fitted on rotor and not extending there through. One of rotor shaft hollow part has its flange supporting slide rigidly fixed thereon to accommodate components of extending device comprising four-link mechanism to slide vanes in-out. Extending device comprises fixation assembly and controlled sleeve-type coupling that has two ring-like sections on its inner surface with straight and skew splines to engage with pinion-and-cam bush and that of four-link mechanism rocker. Outer surface of said sleeve-type bush is provided with pushers to engage with cam arranged on slide inner cylindrical surface. Hub-cab is fitted on slide lower cylindrical part to receive fixation assembly pusher in its inner grooves. Hub-cam outer side has straight splines to engage with crank gear rolling on case ring gear inner side. Profile of every groove in lengthwise section represents broken bicycle sine with sections of constant radius.
EFFECT: higher reliability and efficiency.
