초록 ▼

Installation for pumping a liquid coming from an underground source, comprising a well (10) extending from the surface (12) towards the liquid source (14), the well having a chamber (40) extending substantially over its entire length, at least one tubing (18) passing through the chamber and communicating with the latter, and a set of valves (34), which is intended for putting the chamber selectively in communication with a gas source at a first pressure (36), making it possible for the liquid coming from the source to fill the chamber, and a gas source at a second pressure (38) higher than the first pressure, in order to empty the chamber, the liquid being delivered towards a first outlet (30) by flow through the tubing, characterized in that the said installation comprises, furthermore, a shutter (52), mounted in the tubing (18), and a second conduit (58; 70) leading to a second outlet (74), the shutter being capable of reacting to the density of fluid surrounding it, so that it can deliver a first liquid towards the first outlet (30), a second liquid of higher density being delivered towards the second outlet (74) via the second conduit (58; 70).

대표청구항 ▼

[ It is claimed:] [1.] An installation for pumping liquid from an underground liquid source to the ground surface, comprising a well extending from the ground surface towards the underground liquid source, the well having a chamber extending substantially over its entire length said chamber having an upper end and a lower end, at least one tubing passing through the chamber and communicating therewith through an orifice, a first gas source at a first pressure, a second gas source at a second pressure, means for placing the chamber in selective communication with the gas sources such that when the chamber is in communication with the first gas source, liquid coming from the underground liquid source fills the chamber and when the chamber is in communication with the second gas source, the liquid in the chamber enters the tubing through the orifice and is directed towards a first outlet, a shutter mounted in the tubing below the ground surface at the lower end of the chamber and a second outlet in communication with the shutter via a second conduit, the shutter being capable of reacting to the density of fluid surrounding it such that it can deliver a first liquid towards the first outlet through the orifice in the tubing and a second liquid of higher density towards the second outlet through the second conduit.
