PURPOSE:To obtain a thrust generator with high efficiency by forming a jet nozzle with a cylindrical body having a high-pressure liquid feed port and a high- pressure air feed port and providing a guide cylinder with a fixed length so as to be connected to a high-pressure air nozzle body. CONSTITUTION:The high-pressure liquid and the high-pressure air are injected through injection ports 6, 7 in parallel with each other and gush through a guide cylinder 13. After being injected through the injection port 7, the high-pressure air maintains its straight direction via the inner wall of a guide cylinder 12 without decreasing the injection speed. On the other hand, the high-pressure liquid injected through the injection port 6 is accelerated by the negative pressure of a high-speed cylindrical air flow, thus allowing an extremely high-speed gush. The driving fluid consisting of the high-pressure liquid and the high-pressure air and gushing through an opening provided on one side of the connection section of a conveyance pipe 2 and a suction pipe 1 is injected in the gush direction along the central axis of the conveyance pipe 2, and a conveyed object is sucked by this negative pressure. |
