Abstract

1,070,585. Pure fluid amplifiers. R.W. WARREN. May 14, 1964 [May 20, 1963], No.20033/64. Heading G3H. A pure fluid system incorporates a fluid amplifier 13 having a power nozzle 14, control nozzles 15, 16 and an interaction chamber 17. Two outlet passages 47, 48 lead from chamber 17 and are formed by a divider 27, having passage side walls 30, 31, and passage sidewalls 25, 25a, and 26, 26a. The walls 25, 26 end in cusps 33, 34 formed with the walls 43, 45 of lateral ducts 40, 41 connected to a fixed or ambient pressure. The side walls 25a, 26a lead from the other side of the ducts and are spaced to provide an increased cross-sectional area of the passages 47, 48. The apex 32 of the divider 27 is of concave shape and located opposite the power nozzle 14. With the outlet 48 unblocked and fluid supplied through control nozzle 15, flow takes place as indicated by the arrows. The vortex V3 tends to suck fluid from the passage 47 and flow through passage 48 sucks fluid from the duct 41. When the outlet passage 48 is partially blocked by a member, the velocity of fluid decreases in passage 48 and a vortex is formed between apices 34, 36 which may prevent flow from duct 41 to passage 48. The vortex V3 creates a higher pressure region which prevents flow from passage 47 to passage 48. When the passage 48 is completely blocked, e.g. when passages 47, 48 are connected to the opposite ends of a piston-cylinder device, the flow out of duct 41 from passage 48 increases and the vortex V3 increase the pressure in region 17 to force the jet towards the wall 26. Flow through passage 47 due to the movement of the piston passes out of duct 40.
