Abstract

The fluid controlled device employs boundary layer control to effect switch-over of main jet stream 10 from outlet passage 15 into outlet passage 16 and vice-versa. The control elements 11 and 12 enable the supply of control pressure fluid which is not commingling with stream 10. Element 11 is a generally rigid tube with partitions 21. These are flexed, expanded or displaced by a control pressure fluid supplied to chamber 22. In element 12 there is an entirely resilient balloon 23. Under control pressure, balloon 23 is caused to move outwardly from the wall 26, partitions 21 from walls 24 and 25.

Fluid Controlled Device

The fluid controlled device employs boundary layer control to effect switch- over of main jet stream 10 from outlet passage 15 into outlet passage 16 and vice-versa. The control elements 11 and 12 enable the supply of control pressure fluid which is not commingling with stream 10. Element 11 is a generally rigid tube with partitions 21. These are flexed, expanded or displaced by a control pressure fluid supplied to chamber 22. In element 12 there is an entirely resilient balloon 23. Under control pressure, balloon 23 is caused to move outwardly from the wall 26, partitions 21 from walls 24 and 25.

Element 11 is disposed along walls 24 and 25 of control port 13. Element 12 is deployed along with outer wall 26 of passage 15. Stream 10 can be switched to passage 15 by constricting or blocking port 13 with the aid of element 11, while leaving port 14 open to atmosphere without restriction. Upon expansion of element 12, separation bubble 27 is enlarged sufficiently to divert stream 10 away from wall 26 into opposite outlet passage 16.
