Abstract
Abstract Fluid energy is transferred by first generating pulses of a first fluid in compression waves with alternate high and low pressures. A tubular chamber directs the path of propagation of first fluid pulses. A second fluid is drawn into the chamber by the low pressures between the first fluid compression waves. Subsequent pulses of the first fluid entrap, drive and compress the second fluid. The second fluid is accelerated to the velocity of the first fluid pulses, thereby increasing kinetic energy of the second fluid. When the second fluid is a gas, it is compressed, increasing its potential energy. Subsequently, the fluids are separated. The second fluid with increased energy is used, and the first fluid with spent energy is discarded.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
A fluid energy transfer apparatus comprising: elongate chamber means having a first inlet passage adjacent one end for receiving pulses of a first fluid, a second inlet passage of venturi configuration disposed adjacent the first inlet passage whereby slugs of a second fluid are drawn into the chamber by and between pulses of the first fluid, a first outlet passage adjacent the other end of the chamber means, a second outlet passage joined to the first outlet passage and fluid directing means response to pressure differences in said chamber adjacent the first inlet passage for directing fluid in said chamber to one of said outlet passages in response to relative high fluid pressure in the first inlet passage and for directing fluid in said chamber to the other of said outlet passages in response to relatively low fluid pressure in the first inlet passage.
Claim 2
Dependent Claim

A fluid energy transfer apparatus comprising: elongate chamber means having a first inlet passage adjacent one end for receiving pulses of a first fluid, a second inlet passage of venturi configuration disposed adjacent the first inlet passage whereby slugs of a second fluid are drawn into the chamber by and between pulses of the first fluid, a first outlet passage adjacent the other end of the chamber means, a second outlet passage joined to the first outlet passage and fluid directing means response to pressure differences in said chamber adjacent the first inlet passage for directing fluid in said chamber to one of said outlet passages in response to relative high fluid pressure in the first inlet passage and for directing fluid in said chamber to the other of said outlet passages in response to relatively low fluid pressure in the first inlet passage.
Claim 3
Dependent Claim
14 words
The apparatus of claim 1, wherein said fluid directing means comprises a fluidic valve.
Claim 4
Dependent Claim
65 words
The apparatus of claim 1, wherein the chamber is curved and the first and second inlet passages and the first and second outlet passageS are juxtaposed, and wherein the fluidic valve is constituted by a ''''Y'''' configuration of the exhaust passage and means providing a chamber short-circuiting passage running from the first inlet passage means to the stem of the ''''Y'''' adjacent the arms thereof.
Claim 5
Dependent Claim
41 words
The apparatus of claim 1, wherein the fluid directing means comprises a power input means adjacent the first fluid opening for receiving power from the pulses of the first fluid, and power output means adjacent the juncture of the outlet passage.
Claim 6
Dependent Claim
53 words
The apparatus of claim 1, wherein the power input means comprises a first plate pivot to said chamber means and swingable to selectively close said inlet passages, said power output means comprising a second plate coupled to the first plate and pivoted to said chamber, and swingable to selectively close said outlet passages.
