FIELD: hydraulic machine building. ^ SUBSTANCE: proposed hydraulic gear machine contains gears installed in cylindrical bores of housing and at least pair of compensators of end face clearances adjoining end faces of gears and mated through arc-shaped cavity. Machine is provided with seal from rear side of compensators. Arc-shaped cavity is made over entire height of one of compensators. Other compensator mated with first one adjoins end face of gear projecting over end face of other gear. Said compensators, displacing in axial direction relative to each other, adjoin tightly end faces of gears even when gear rims are of different width and when end face of one gear projects over end face of other gear. Bushing without arc-shaped cavity adjoins end face of gear projecting over end face of other gear initially mating without clearances with other bushing and with gears. ^ EFFECT: increased delivery coefficient of hydraulic machine. ^ 2 cl, 5 dwg |
