Abstract (en)

Disclosed is a vane motor including: a casing including an inlet port and an outlet port, through which a pressurized fluid comes in or out; and a rotor being installed in the casing, turning around a rotational shaft by the pressurized fluid and including a rotor body which has a substantially cylindrical shape and an axis coinciding with an axis of the rotational shaft and a plurality of vanes which is installed in grooves formed on an outer circumferential surface of the rotor body and has a portion protruding from the groove and having a length varied in accordance with a rotational phase, wherein a rear edge portion of the opening of the groove formed on the rotor body to receive the vane is partially removed to form an enlarged portion through which a rear surface of the vane is more exposed.According to the present invention, more pressurized fluid flows quickly in the space between the rotor body and the casing, thereby increasing the pressure applied to the vane and improving rotation efficiency of the rotor which is rotated by the pressure.
