Abstract: A planetary hydraulic motor comprising a housing 1 having a stator gear 2, a housing 1 accommodating a shaft 5 having a gear 6 fixed thereon, a ring member 7 arranged eccentrically relative to the shaft 5, a cover plate 3 for mounting the rotary hydraulic motor and a cover plate 4 for feeding a working fluid, the two cover plates 3 and 4 being positioned on the both sides of the stator gear 2, and a valving mechanism. The valving mechanism includes a distributor 11 arranged in the cover plate 4 and a control valve 12, the distributor 11 and the control valve 12 being adapted to cooperate by their working surfaces 13, the latter being provided with valving ports 14, 17 an 17'. The valving ports 14 of the distributor 11 are arranged radially non-equidistantly, whereas the control valve 12 is arranged in the cover plate 4 so as to define an annular chamber 21. The housing 1 with its stator gear 2 is adapted to be displaced angularly relative to the cover plates 3 and 4.
