1,163,326. Bearings. MECANORGA SOC. ANON. 17 Nov., 1966 [29 Nov., 1965], No. 51651/66. Heading F2A. [Also in Division G3] A fluid bearing has a constant clearance maintained by means controlling the flow of fluid to opposite zones 7, 8 of the clearance, the means comprising a pressure-sensitive element 21, 22 separating a first chamber 26 connected to the clearance, and a second chamber 33, the element 21, 22 controlling a valve 36 itself controlling the flow to the zones 7, 8. In Fig. 3 gas enters the chambers from passage 23 and orifices 24, 31, and exits from chamber 26 by outlets 28, 29 and from chamber 33 by outlet 35. Movement of shaft 2 towards outlet 28 increases the pressure in chamber 26 and depresses slide 21 in diaphragm 22 and also valve 36. The gap between valve 36 and shoulder 41 is thus increased and that between valve 36 and shoulder 40 is decreased, thus increasing flow to portion 7 from passage 37 and decreasing it to portion 8. When the slide 21 moves down the collar 30 decreases the flow from outlets 29, 35. |
