Abstract
Official abstract text for this publication.
An electric pump includes a case, and a motor that includes a rotor and a stator and is surrounded by the case. The case includes an introduction pipe portion for introducing a fluid and a discharge pipe portion for discharging the fluid. The rotor is disposed in a space surrounded by the case and the stator and communicating with the introduction pipe portion and the discharge pipe portion. The rotor includes a first blade member, a second blade member, and a relay portion. An outer diameter of the relay portion is smaller than an outer diameter of at least one of the first and second blade members. The relay portion is positioned between the first blade member and the second blade member.
First claim
Opening claim text (preview).
What is claimed is: 1 . An electric pump comprising: a case; a motor that includes a rotor and a stator and is surrounded by the case; and a partition member that partitions the rotor and the stator, wherein the case includes an introduction pipe portion for introducing a fluid and a discharge pipe portion for discharging the fluid, the rotor is disposed in a space surrounded by the case, the stator, and the partition member and communicating with the introduction pipe portion and the discharge pipe portion, the rotor includes a first blade member, a second blade member, and a relay portion, an outer diameter of the relay portion is smaller than an outer diameter of at least one of the first and second blade members, the relay portion is positioned between the first blade member and the second blade member, each of the introduction pipe portion and the discharge pipe portion is located closer to the first blade member than to the second blade member, the space is sealed by the case and the partition member except at the introduction pipe portion and the discharge pipe portion, and the second blade member is surrounded by the partition member. 2 . The electric pump according to claim 1 , wherein the second blade member includes a plurality of grooves extending linearly in a radial direction. 3 . The electric pump according to claim 2 , wherein a width of the groove perpendicular to the radial direction is constant. 4 . The electric pump according to claim 2 , wherein the rotor includes a magnet, and an outer diameter of the second blade member is smaller than an outer diameter of the magnet. 5 . The electric pump according to claim 1 , wherein the first blade member is surrounded by the case, and the second blade member is surrounded by the stator. 6 . The electric pump according to claim 1 , wherein the rotor includes a magnet, the first blade member is located on one side with respect to the magnet, and the second blade member is located on the other side with respect to the magnet.
