A rotor type pump is provided. A rotor rotates and closely contacts an inner surface of a chamber, and a cam controls a sealing part, so that during a compression procedure, the sealing part, a convex surface of the rotor, and an inner surface of the chamber form a substantially hermetic space, and when a gas in the chamber is compressed to a set pressure, the compressed gas is guided out. Therefore, a smooth surface of the rotor closely contacts the inner surface of the chamber, and the gas in the chamber is compressed in a rotational manner, in which the to-and-fro movement of a piston is not required, and a dead point is prevented, so that operation is smooth and noise is not easily generated. Further, the rotor type pump does not need to use a lubricating fluid and offers extremely large compression capacity and excellent efficiency. |
