FIELD: mechanical engineering. SUBSTANCE: rotary spherical machine has housing with spherical inner space, input and output shafts, input shaft is rigidly coupled with first piston made in form of spherical semiring getting into corresponding ring space of spherical rotor. Output shaft is rigidly connected to second piston made similar to first one and installed crosswise relative to first piston on opposite side of spherical rotor in corresponding ring space. EFFECT: enlarged operating capabilities. 2 dwg
