<p>1,195,003. Fluid regulation. BENDIX CORP. Jan. 9, 1969 [Feb. 15, 1968], No.1435/69. Heading G3H. A vortex fluid amplifier 10 constructed of laminae 14, 16, 20, 22, 24, 26 secured together in surface engagement, comprises a cylindrical vortex chamber 28 having a supply fluid inlet 30 at pressure P s , a control fluid inlet 32 tangential of the vortex chamber at pressure P c , and an exit passage 34 axial of the chamber. Lamina 20 of critical thickness defines a vent 36, and adjacent lamina 22 is drilled with a pick-off aperture 38 coaxial with exit passage 34 while laminae 24, 26 define discharge passage 39. In operation, fluid issues from exit passage 34 in conical configuration; the divergence being determined by P c so that the flow through the pick-off aperture and the pressure P 0 in the discharge is inversely dependent on P c .</p> |
