Abstract
An inline type pump in which a rotor having an axial flow vane is arranged inside the cylindrical stator. The fluid is discharged from the discharging port after a rotating kinetic energy of the fluid transferred by the axial flow vane toward the discharging port is changed into a static pressure energy at the pressure chamber. With such an arrangement as above, it is possible to increase a fluid supplying efficiency after satisfying a small-sized structure and further it is possible to increase an output of the pump as well as its efficiency.
