Abstract
1424371 Fluid-pressure servomotor systems G TEATINI 8 Feb 1973 [29 Feb 1972] 6323/73 Heading G3P A flow regulating valve comprises a closure member 9, Fig. 1, slidably arranged within a chamber 4 connected with upstream flow via throttled passage 5 and with downstream flow via throttled passage 16. Adjustment of lever 25 compresses spring 30 so that adjustable spring 28 can pivot lever 20 about pin 21 in a direction causing needle 18 to reduce the throttling of passage 16. The consequent fall in pressure in chamber 4 causes the closure member 9 to move away from its seat 10 to an equilibrium position and establish throughflow. Variations in the flow-rate are sensed by a disc 24 causing movement of the throttle 18 and consequent compensating movement of the closure member 9. The latter may also be moved in accordance with other variables such as changes in upstream and downstream pressure or any pressure differential. In Fig. 3 (not shown), the upper end of the lever 20 is acted on, in addition to the spring 28, by means (31) responsive to downstream pressure. In Fig. 4 (not shown), the lever 20 is replaced by a pivoted lever and leaf-spring device (122, 125), the closure member is arranged at the upstream end of the valve, and the needle throttle is replaced by a piston-type slide valve (115).
