FIELD: machine building.SUBSTANCE: invention relates to positive-displacement hydraulic machines with rotary working tools and can be applied in pumps and engines. Proposed machine comprises housing 1, stationary round ring gear 2 with inner gearing, round sun gear 3 with outer gearing, two floating pinions 4 engaged with said ring and sun gears, eccentric offset from ring gear 2 axis by distance equal to eccentric eccentricity, fixed end covers 5 and system of channels 7 and 8 for fluid feed and discharge, respectively. Ring and sun gears 2 and 3 have identical number of teeth. Sun gear 3 is rigidly engaged with rotary eccentric.EFFECT: simplified design, higher wear resistance, efficiency and power output.5 cl, 9 dwg |
