Summary: | A rotor structure of a side feeding type external LPG pump is provided to suppress generation of cavitations by cooling the rotor using LPG fuel flowing through one or both side surfaces of the rotor. A rotor structure of a side feeding type external LPG pump includes a motor part(120), and a circulation chamber(110). The motor part accommodates a motor. The circulation chamber circulates LPG fuel using a rotational force provided by the motor. A rotor and a roller are disposed in a cylinder(144). A first plate(141) and a second plate(145) are disposed on and under the cylinder. The LPG fuel is sucked through a suction port(112) in a tangential direction of the rotor and discharged through a discharge port(113). Grooves are formed at one or both surfaces of the rotor. The grooves include a first groove having a straight shape, and a second groove having a fan shape. |
