Abstract 1,067,180. Pure fluid amplifiers. GENERAL ELECTRIC CO. Oct.21, 1965 [Dec.21, 1964], No. 44575/65. Heading G3H. A pure fluid device comprises an inlet passage 10 leading to a main jet orifice 13 and two outlet passages 15, 16 divided by a wall 14. A small port 17 in the side wall leads to the ambient atmosphere through a conduit 18 while a large port 19 leads to the ambient atmosphere through a conduit 20 provide with a valve. The walls downstream of the ports 17, 19 are offset by small and large amounts respectively from the sides of the nozzles 13. With both passages open to the atmosphere, the jet adheres to the wall 8 and flows out of the passage 15. The wall 14 is provided with a notch 24 which causes a vortex 29 to block flow from the passage 16 being sucked in by the jet. When the valve in conduit 20 is closed the pressure gradient across the jet causes it to switch to the outlet 16. The jet reverts to the outlet 15 when the valve is reopened.
A TWO PHASE MEDIUM FLUID DEVICE COMPRISING: (A) AN INLET PASSAGE CONNECTING WITH A PAIR OF OUTLET PASSAGES, (B) A RELATIVELY SMALL BIASING PORT CONNECTING ONE WALL OF SAID INLET PASSAGE TO AMBIENT PRESSURE TO BIAS LIQUID FLOWING THROUGH SAID INLET PASSAGE FOR FLOW ALONG SAID ONE WALL AND THROUGH A FIRST OF SAID OUTLET PASSAGES, (C) A RELATIVELY LARGE CONTROL PORT OPPOSITE SAID BIASING PORT, CONNECTING THE OTHER WALL OF SAID INLET PASSAGE TO AMBIENT PRESSURE, (D) MEANS TO SELECTIVELY CLOSE SAID CONTROL PORT TO DIVERT LIQUID FLOWING THROUGH SAID INLET PASSAGE FOR FLOW ALONG SAID OTHER WALL AND THROUGH SAID SECOND OF SAID OUTLET PASSAGES, (E) AND A MEMBER BETWEEN SAID OUTLET PASSAGE INCLUDING A NOTCH EXPOSED TO THE LIQUID DURING FLOW THROUGH SAID FIRST OUTLET PASSAGE TO CAUSE A VERTEX FLOW OF A PORTION OF THE LIQUID FOR CLOSING SAID SECONE OUTLET PASSAGE WHEREBY CLOSING OF SAID CONTROL PORT IS EFFECTIVE TO DIVERT THE FLOW OF LIQUID TO SAID SECOND OUTLET PASSAGE.
