Abstract
634,495. Valves. CARBA AKT.-GES., and EICHMANN, T. Nov. 6, 1946, No. 33007. [Class 135] [Also in Group XXVI] An anchoring for the diaphragm 3 of a diaphragm piston for actuating a thermally controlled regulating valve comprises an anchoring mass 10 which fills an outwardly widening space 9 formed on both sides of the diaphragm and is connected to the latter and to the parts 1, 2 of the diaphragm casing by a fusing weld so that the two compartments 4, 5 formed between the diaphragm and the casing parts are sealed from each other and from the atmosphere, the casing part 1 being threaded to receive a cap 11 which is adapted to seal the anchoring mass from the atmosphere to prevent corrosion and also to press the casing parts together so that they grip the diaphragm. The anchoring mass may be of lead or tin cast into the space 9. Wedge-shaped annular sealing ribs 12, 13 formed on the cap are adapted to press against the casing parts to effect the seal. The rib 13 may alternatively be formed in the same plane as the rib 12 and adapted to press on the upper edge of the part 1. An inlet pipe 7 for gaseous cooling means opens into the compartment 5 whilst the lower part of the diaphragm is connected to a disc 8 which controls the valve body.
