Abstract
PURPOSE:To prevent blocking due to foreign matter by making cutting edges formed on the boundary parts between groove parts recessedly provided on the inner face of a cylindrical member and the inner face a stator while making cutting edges provided on a pump shaft and having an end face which is tapering off toward the center a rotor. CONSTITUTION:A cutting device consists of a stator 7 and a rotor 8. The stator 7 is formed with cutting edges 12 on the boundary part between the groove parts 11 on the inner face 10 of a cylindrical member and the inner face 10. In the rotor 8, the end face 14 of a cylindrical core part 13 is tapering off toward the center and cutting edges 16 are projected on the outer peripheral face. Hence, the gap passage between the stator and the rotor can be made wider than that in the past preventing blocking due to foreign matter.
