Abstract

552,944. Diaphragm valves TRUMP, A. L., and SUTTON, F. Feb. 5, 1942, No. 1535. [Class 135] The attachment face of a diaphragm. 6 for controlling high vacua or dangerous fluids is formed with a peripheral groove 17 connected with the exterior of the valve body means being provided for producing a pressure differential between the groove and the passage through the valve body. As shown, the connection is made through an annular space 23 in the joint with a pipe line, but it may be made to the interior of the bonnet 7, and the latter connected to the exterior by a pipe 29. Specification 516,526 is referred to.
