Described one-way valve is resisted against that plug to carry out spacing, described plug be that ball rises formula high-pressure drain plug.
Described casting duct is arranged at body shell front end, and described casting duct is local half-duplex channel, and skew is arranged at the one end in hydraulic fluid port face.
Described casting duct is linked up by the oil passage in output shaft and one-way valve as the Leakage Energy of motor.
Above technological scheme is further improved: right angle type is arranged in the one end, hydraulic fluid port face on described body shell, and hydraulic fluid port face arranges the boss of two installation screws.
Compared with the axle distributing cycloid motor of prior art, such scheme of the present utility model well eliminates the inclined hole structure of existing one-way valve oil duct, simplify the structure of one-way valve, improve the sealing reliability of one-way valve body, hydraulic fluid port face can process the hydraulic fluid port of oblique hydraulic fluid port or vertical axial, and installs plug-in overflow valve.
