Title:
FLUID TRANSFER DEVICE
Document Type and Number:
Japanese Patent JP2022070105
Kind Code:
A
Abstract:
To provide a fluid transfer device that eliminates the necessity of a power supply, can generate a siphon phenomenon and has a compact configuration.SOLUTION: A fluid transfer device 1 includes: a transfer pipe 10 extending from a storage part 3 storing fluid toward a transfer destination 50; and pressure generating means 20 connected to the transfer pipe 10 and generating pressure for sucking up fluid in the storage part 3 to a water level starting a siphon in the transfer pipe 10. The pressure generating means 20 includes a negative pressure generating part 41 disposed between an upstream side transfer pipe 11 serving as a storage part 3 side and a downstream side transfer pipe 12 serving as a transfer destination 50 side. The negative pressure generating part 41 includes: an inflow port (branch pipe part 44a) connected to the upstream side transfer pipe 11; and an outflow port (lower end part of a straight pipe part 44b) connected to the downstream side transfer pipe 12.SELECTED DRAWING: Figure 1
