Ejector nozzle and ejector including same

Abstract

The present disclosure provides an ejector nozzle and an ejector including the same. The ejector nozzle includes a first tube having a first flow path into which a fluid is introduced, and a second tube provided outside the first tube and having an inner diameter larger than an inner diameter of the first tube, the second tube defining a second flow path between the first tube and the second tube, in which the first tube further includes a communication port that penetrates the first tube to allow the first flow path to communicate with the second flow path and is openably and closably provided, and in which when the communication port is opened, a part of the fluid flowing in the first flow path is allowed to flow along the second flow path.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2019-0167676 filed with the Korean Intellectual Property Office on December 16, 2019, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an injector nozzle and an injector including the same, and more particularly, the present invention relates to an injector nozzle satisfying both a low flow area and a high flow area and an injector including the same. Background technique [0004] In systems where fluid is moved by using injectors, the diameter of the nozzle is considered to be an important factor. [0005] If the size of the nozzle is large, it is easy to achieve desired performance in the high flow portion, but the flow velocity is reduced, and the performance of the injector is deteriorated in the low flow portion. Conversely, if the size of the nozzle is sma...

Problems solved by technology

[0005] If the size of the nozzle is large, it is easy to achieve the desired performance in the high flow section, but the flow velocity is reduced, and the performance of the injector is deteriorated in the low flow section

Conversely, if the size of the nozzle is small, high flow velocity may be produced in the low flow section, but it is difficult to utilize the nozzle in the high flow section because it is difficult to pass a large amount of fluid through the nozzle in the high flow section
