Abstract:
An inline type pump comprising:a cylindrical stator arranged between a suction port and a discharging port; a rotor rotatably arranged inside the stator; an axial flow vane integrally arranged with the rotor for axially feeding fluid sucked from the suction port toward the discharging port; and a pressure chamber for converting a rotational kinetic energy of the fluid sent toward the discharging port by the axial flow vane of the rotor into a static pressure energy, wherein the rotor includes a plurality of salient poles at its outer diameter and is formed with an axial communicated helical recess at its outer circumference to constitute the axial flow vane, and wherein the pressure chamber is a space having a larger inner diameter than an inner diameter of at least the discharging port in a direction crossing at a right angle with a rotating shaft of the rotor.
