Abstract

1330643 Fluid regulation NATIONAL RESEARCH DEVELOPMENT CORP 30 Sept 1970 [30 June 1969] 33030/69 Heading G3H A fluid vortex amplifier, wherein the pressure of the control signal need not be as high as the pressure of the input signal, comprises an unevenly shaped vortex chamber 11 into which leads an input signal 13 derived from a passage 12. The signal 13 upon infringing against a chamber wall portion 15, divides unevenly into two separate flows 16, 17 which subsequently attain spiraling paths so creating two uneven vortices 18 and 19. The strength of the output signal present in output port 22 formed in a first flat face of the chamber 11, and hence also the relative strength of the two vortices 18 and 19, is dependent upon the nature of a control signal present in a control port 23 formed in the same flat face of the chamber 11, the port 23 being disposed opposite to a vent port 21 for the vortex flow 19, a further vent port 20 for the vortex flow 18 being offset relatively to the outlet port 22 and being provided in the second flat chamber wall. Figs. 1c, 1d, 1e, Fig. 1<SP>1</SP> and Figs. 2 to 9 (not shown), depict various modifications of the basic concept above outlined wherein control of flow from an inlet to an outlet is effected by the creation of relatively variable vortices.
