ROTARY MACHINE OF VOLUMETRIC TYPE Russian patent published in 2016 - IPC F01C1/04 

FIELD: machine building.

SUBSTANCE: invention can be used to drive mechanical energy consumers. Rotary machine of volumetric type consists of housing 1 with profiled element 2 made in form of a protrusion, hollow wheel-divider 6 with a hole for element 2 and hollow central body 4 with feed channel and working medium discharge channel and with a longitudinal radial slot for wheel 6. Wheel 6 is installed in slot of body 4 with possibility of rotation around its longitudinal axis. Housing 1 is installed with possibility of rotation around its axis in one plane with axis of rotation of wheel 6 and kinematically connected to it. Machine is equipped with tubular shaped element 5 with feed channel and working medium discharge channel and control valves 12, 13, installed on working medium discharge channels of element 5 and body 4. Side surface of element 5 is in form of two interfaced geometrical solids of revolution. Element 5 is rigidly connected with body 4 and installed in wheel 6 with possibility of its rolling at inner surface of one solid of revolution. Surface of other solid of revolution is equidistant from axis of body 4 and technologically interfaced with element 2.

EFFECT: higher efficiency, reduced fuel consumption.
