Document Type and Number:
WIPO Patent Application WO/1982/003247
Kind Code:
A1
Abstract:
A planetary hydromotor comprises a casing (4) with a stator gear (5), a cover (6) for fixing the planetary hydromotor, a cover (7) for supplying a working fluid with a valve (8) mounted in that cover. Between the surfaces of the valve (8) and the cover (7) for supplying a working fluid are formed one chamber (1) for supplying the working fluid connected to their own windows (32) provided on the butt-end surface of the valve (8), and several chambers (2, 3) for discharging the working fluid connected to their windows (33, 34) provided on the same surface of the valve (8), these several chambers (2, 3) being either interconnected to each other or at least one chamber (3) for discharging the working fluid being connected to the discharge and the other chambers (2) for discharging the working fluid being connected to the chamber (1) for feeding the working fluid. In the casing (4) are mounted as well a shaft (10) with a gear (11) and a distributor (12), and an annular rotor (13) mounted eccentrically on the shaft (10) and interacting with the gear (11) of the shaft and with the stator gear (5) of the casing. The stator gear (5) and the external gear rim (15) of the annular rotor form together a gear pair with working chambers (16) of variable volume.
