Abstract
A jet pump is disclosed through which a liquid flows. The jet pump includes a jet nozzle including an injection port for injecting the liquid. The jet pump also includes a throat pipe including a throat passage that extends linearly. The throat pipe includes a downstream side with an open part, and the liquid injected from the injection port flows into the throat passage. The liquid in the throat passage forms a liquid seal across a cross section of the throat passage to generate negative pressure, which introduces the liquid into the throat passage.
