<p>1,034,312. Pure fluid amplifiers. SPERRY RAND CORPORATION. Feb. 14, 1963 [Sept 4, 1962], No. 5973/63. Addition to 1,027,817. Heading G3H. A pure fluid amplifier has a nozzle 46 for power fluid, a control nozzle 60 to deflect the power stream from a wall 48 and cause it to follow a wall 50, and a feedback nozzle 66 which, after an interval, causes the power stream to revert to the wall 48. The power stream tends to follow either wall 48, 50 in the absence of a deflecting stream by the creation of a low pressure boundary layer region. The outlet associated with each wall 48, 50 are divided into two branches 30, 32 and 36, 38. An additional outlet 34 receives a pulse each time the power stream is deflected from one wall to the other. The two branches 32, 36 are connected by pipes 54, 62 with an output device which may be e.g. a pure fluid or fluid-actuated data processing device, and the outlet 34 may be connected to a similar output device. An outlet 64 from a chamber 26 terminating the branch 38 is connected to a pump &c. for supplying fluid to, or removing fluid from, the chamber at a controlled rate thereby to govern the time over which fluid from the power stream can build up a sufficient pressure in the chamber 26 and feedback channel 40 to cause the power stream to be deflected from the wall 50 to the wall 48. Modifications are described in which the outlet 34, or that outlet together with the branch 30, are omitted.</p> |
