Embodiment Construction

[0027] The electric pump P in an embodiment disclosed herein will be described below with reference to the drawings. In the example given in this embodiment, an electric water pump (hereinafter simply referred to as "electric pump P") for circulating a coolant (an example of fluid) for cooling a vehicle engine will be described. However, the present invention is not limited to the embodiments described below, and can be modified in various forms as long as such modifications do not deviate from the gist of the present invention. In the explanation to be given below, figure 1 The front and rear of the middle rotor 5 in the longitudinal direction refer to the side on which the propeller 6 is arranged and the opposite side to the propeller 6, respectively.

[0028] figure 1 The overall configuration of the electric pump P in this embodiment is shown. The electric pump P includes: a casing 1 made of resin; a metal shaft (shaft member) 3 fixed to the casing 1; a cylindrical bush...

Abstract

An electric pump (P) includes: a case (1)a shaft member (3) fixed to the case, a cylindrical bearing (4) inserted on the outside of the shaft member, a rotor (5) configured as a member separate from the bearing, and configured to rotate integrally with the bearing and an impeller (6) fixed to one end of the rotor, wherein a discharge path (52) is formed between the bearing and the rotor along an axial direction, and allows fluid to return to the impeller therethrough, the fluid flowing from the outer circumference of the impeller into the case, and circulating in the case.

Description

technical field [0001] The present invention relates to an electric pump including a rotor rotatably supported by a shaft member and a propeller fixed to one end of the rotor. Background technique [0002] In the related art, an electric pump including a shaft member fixed to a casing and a rotor inserted outside the shaft member is known (for example, see JP2006-296125A (Reference Document 1)). A passage is formed through a region between the shaft member and the rotor along the axis direction. A balance hole for releasing fluid pressure in the housing is formed radially outside the passage, passing through one end of the rotor and communicating with the blade member of the propeller. [0003] A part of the fluid flowing due to the rotation of the impeller cools electronic parts and the like while circulating inside the case, and returns to the impeller through passages or balance holes. At this time, the fluid passing through the passage acts as a lubricant that lubricat...
