FIELD: engines and pumps. ^ SUBSTANCE: invention relates to machine building, mainly to pneumatic rotary drives. Proposed engine comprises rotor 2 with three vanes 3 inclined to rotor radius, stator 3 and end face covers 4 with holes 6. Outlet holes 6 are shifted towards rotational axis of rotor 2 from inner surface of stator 1 to make ledges 8 in assembled engine to allow circulation of lubricant layer on inner surface of stator 1 and inhibit lubricant ejection into outlet holes 6. ^ EFFECT: higher RPM and specific power output. ^ 2 dwg |
