Abstract
Official abstract text for this publication.
A centrifugal pump includes: a rotating blade member including an impeller member and a rotor magnet associated with the impeller member, a main body casing in which the rotating blade member is accommodated, a coil portion that rotates the rotating blade member, wherein the coil portion is located on a periphery of the rotor magnet, and an axial member which is associated with the main body casing, wherein the rotating blade member pivots around the axial member. A clearance, in which the rotor magnet is allowed to move, is provided between the blade member and the rotor magnet.
First claim
Opening claim text (preview).
What is claimed: 1 . A centrifugal pump comprising: a rotating blade member including an impeller member and a rotor magnet associated with the impeller member; a main body casing in which the rotating blade member is accommodated; a coil portion that rotates the rotating blade member, wherein the coil portion is located on a periphery of the rotor magnet; and an axial member which is associated with the main body casing, wherein the rotating blade member pivots around the axial member, wherein a clearance, in which the rotor magnet is allowed to move, is provided between the blade member and the rotor magnet. 2 . The centrifugal pump of claim 1 , wherein the clearance between the impeller member and the rotor magnet includes a radial clearance between the impeller member and the rotor magnet. 3 . The centrifugal pump of claim 1 , wherein the clearance between the impeller member and the rotor magnet includes an axial clearance between the impeller member and the rotor magnet. 4 . The centrifugal pump of claim 1 , wherein the clearance between the blade member and the rotor magnet includes a radial clearance r between the impeller member and the rotor magnet and an axial clearance h between the impeller member and the rotor magnet, and r is smaller than h. 5 . The centrifugal pump of claim 1 , further comprising: a dropout preventing means to prevent the impeller member and the rotor magnet from dropping out. 6 . The centrifugal pump of claim 1 , wherein the main body casing has a first end and a second end in an axial direction of the axial member, and the axial member is fixed at the first end and the second end. 7 . The centrifugal pump of claim 1 , wherein the main body casing has a third end at a side of the rotor magnet, and the axial member is fixed at the third end.
