Abstract
492,806. Pressure-regulating valves. EYRE, J. R. Jan. 25, 1937, No. 2107. [Class 135] A pressure regulator has parts of the actuating member loaded by supplementary springs in series with the main springs tc give a high lift to the valve for a small pressure variation. In the form shown a simple lift valve member 10 is actuated by a differential diaphragm, the upper side of the smaller diaphragm 17 being sub ject to inlet pressure to balance the valve while outlet pressure is admitted to the cham ber between the diaphragms. The large] diaphragm 18 is back ed by a central disc 31 coupled by a spin dle 15 to the valve member 10 and by one or more annular rings 33. Shoulders are formed on the disc, rings and casing to limit the relative movements of these parts. The annular ring is loaded by a pair of springs 41 connected to a cross-head 37 engaging a spherically faced washer 36 resting on the ring. An additional loading spring 40 is arranged between the central disc and a cross-head 38 connected by pillars 39 to the cross-head 37. The single diaphragm may be replaced by a pair of diaphragms each supported by a single bucking member.
