Abstract:
A fluid extraction apparatus comprising:a first passage;a fluid providing mechanism connected to an upstream side of the first passage and providing a first fluid to the first passage;a fluid flow area control device provided along the first passage and reducing a cross-sectional area of the first passage through which the first fluid passes;a downstream passage connected to the first passage downstream of the fluid flow area control device;a second passage connected to the downstream passage downstream of the fluid flow area control device, the second passage being distinct from the first passage upstream of the fluid flow area control device;whereby the pressure of the first fluid at a downstream side of the fluid flow area control device is reduced to bring a second fluid from the second passage into the downstream passage, the second fluid being separate from the first fluid in the first passage before the first fluid and the second fluid meet in the downstream passage.
