摘要: A vane-type hydraulic motor includes a rotor (30) having a main shaft (70) and a plurality of vanes (35), a cam casing (10) having a chamber (11) for rotatably housing the rotor (30), a first port (13) and a second port (15) for supplying a working fluid into the chamber (11) and discharging the working fluid from the chamber (11). A bypass path (80) is provided for allowing the working fluid to flow from bearing portions (51, 61) supporting the main shaft (70). A drain port (17) is provided for discharging the working fluid to the exterior.
