Title:
PUMP WITHOUT PUMP
Document Type and Number:
Japanese Patent JPH1189180
Kind Code:
A
Abstract:

To reduce in size a pump without pump by forming protruding parts of only a rotor or a rotor and stator by skewing, and sucking and discharging liquid from one end side to the other end side by a pressure difference generated at both sides of the rotor and stator having oblique protruding parts, thereby simplifying a constitution.

Protruding 1A parts to become ferromagnetic parts of a rotor 1 each has a structure that the parts are skewed at a suitable oblique angle, and functions as a blade of a pump. Similarly to a conventional SR motor, when coils 2A of a stator 2 side are suitably energized and excited, the protruding 1A parts of the rotor 1 are attracted by generated magnetic attraction force and rotated. And, fluid is sucked from a suction port 3A of a low pressure side by a pressure difference of right and left sides of a housing 3 generated by the rotation, passed through a gap between the rotor 1 and the stator 2, and discharged from a discharge port 3B of a high pressure side to the exterior. Thus, the fluid can be transferred in a predetermined direction.
