Реферат: The present invention relates to technology for preventing dry running of a submerged-type pump used for transferring liquefied gas such as liquefied ammonia, liquid hydrogen, liquid nitrogen, liquefied natural gas, liquefied ethylene gas, and liquefied petroleum gas. A flow path switching device (5) comprises a flow path structure (45) that has a first flow path (41), a second flow path (42), and a third flow path (43), and a valve (47) that is disposed in the flow path structure (45) and that selectively connects the third flow path (43) to the first flow path (41) or the second flow path (42), wherein the first flow path (41) is connected to a discharge opening (1b) of the submerged-type pump (1), the second flow path (42) is connected to the inside of an intake container (2), and the third flow path (43) is connected to a discharge port (8) of the intake container (2).
