Apparatus employing pressure transients for transporting fluids

An apparatus for transporting fluids from a first reservoir to a second reservoir, the apparatus comprising:

• at least one partly enclosed space;
• at least one body placed in said at least one partly enclosed space, where said at least one body is movable relatively to the interior of said at least one partly enclosed space;
• an opening in said at least one enclosed space which allows a fluid to flow alternately in the direction into and out of said at least one partly enclosed space and which opening is connected to a third conduit;
• and
• at least one first conduit and at least one second conduit in fluid communication with the opening via the third conduit, and connected to the first and second reservoir, respectively;
• wherein at least one solid object is arranged to fall onto and collide with said at least one body so as to generate pressure transients in at least one of said at least one partly enclosed space in order to produce a flow of fluid in the direction from said at least one partly enclosed space towards said second reservoir, and to produce a flow of fluid in the direction from said first reservoir towards said at least one partly enclosed space.
