POSITIVE DISPLACEMENT ROTARY MACHINE Russian patent published in 2006 - IPC F01C1/356 

FIELD: mechanical engineering; rotary machines of positive displacement action.

SUBSTANCE: proposed positive displacement rotary machine contains stator with rotary support secured inside, housing installed inside over outer diameter for rotation around axle between two side disks arranged in stator, shaft arranged eccentrically in housing, blade installed for sliding inside retainer installed in housing and two supply ports, one of which is made in one of disks. Shaft is made hollow. Blade is rigidly coupled with shaft. Other supply port is made in other disk. Supply are arranged at both sides of blade, one of them communicates with inner space of stator, and the other, with inner space of shaft. Both side disks are arranged in stator freely relative to stator with guaranteed clearance and are connected on shaft coaxially with provision of rigid coupling with shaft and with blade.

EFFECT: reduced wear, provision of operation without lubrication, reduced heating, increased volumetric efficiency.
