Abstract

533,116. Diaphragm valves. SAUNDERS VALVE CO., Ltd., and SAUNDERS, P. K. Oct. 10, 1939, No. 27604. [Class 135] A diaphragm valve of the kind provided with a compressor member for pressing the diaphragm against its seat, said member having a series of projecting fingers which inter-engage a series of diaphragm supporting toes projecting inwards from the valve bonnet has the compressor guided by one or more deep toes. In the form shown in Figs. 1 and 3, the valve is actuated by a screwed spindle 14 rotatably mounted in the bonnet 5 and engaging a nut 13 mounted in the compressor member 6. This member has a pair of arms projecting transversely to the plane of the weir 2 and provided with a series of transverse fingers 8, 9. The central fingers 9 engage grooves in the bonnet so providing a continuous surface right across the compressor in the plane of the weir. Toes 12 on the bonnet of considerable depth guide the compressor by contacting with its central cylindrical part. Specifications 321,892, [Class 135], 362,084, 434,664, 434,684, 468,664, 516,526 and 516,569.
