Abstract
Official abstract text for this publication.
A centrifugal pump for pressurizing fluid by using centrifugal force has an impeller and a casing. The impeller is operated rotatably by an actuator. The casing houses the impeller. The impeller has blades arranged one after another in a circumferential direction of the impeller, and a passage is defined between the blades adjacent to each other in the circumferential direction. The passage has a linear portion and a curved portion. The linear portion extends linearly and has a uniform cross section. The curved portion is connected to an end of the linear portion, extends as being curved to a radial-outer side of the impeller, and decreases in cross section toward the radial-outer side.
First claim
Opening claim text (preview).
What is claimed is: 1 . A centrifugal pump for pressurizing fluid by using centrifugal force, the centrifugal pump comprising: an impeller operated rotatably by an actuator; and a casing housing the impeller, wherein the impeller has blades arranged one after another in a circumferential direction of the impeller, and a passage is defined between the blades adjacent to each other in the circumferential direction, and the passage has: a linear portion extending linearly and having a uniform cross section; and a curved portion (i) connected to an end of the linear portion, (ii) extending as being curved to a radial-outer side of the impeller, and (iii) decreasing in cross section toward the radial-outer side. 2 . The centrifugal pump according to claim 1 , wherein the passage has an opening portion that is open on the radial-outer side of the impeller, and fluid after being pressurized flows from the opening portion, and the fluid flows from the opening portion in a direction that is opposite to a rotation direction of the impeller.
