置における流体管の接続装置。 A screw hole is formed in the fluid discharge port of the pump device, a fluid passage having a smaller diameter than the screw hole is opened at the bottom of the screw hole to form a support end surface, and a seat union having a through hole formed is seated on the support end surface. A fluid pipe in a pump device in which a flared portion formed at the tip of an equal diameter portion of a fluid pipe is brought into contact with the seat union, and the flared portion is brought into close contact with the seat union by a flare nut screwed into the screw hole. In the fluid pipe in the pump device, a throttle member made of a shape memory alloy that deforms into a shape that reduces the passage area of the through hole of the seat union at high temperatures is fixed to the end face of the seat union. Connection device.
