10,734. Samson-Apparate-Bau Ges. July 23,1914, [Convention date]. Thermostats; steam-traps.-Relates to devices in which an expansible fluid operates a valve in a thermostatic apparatus or a steam-trap, and in which a piston with a corrngated flexible packing tube acts as a buffer against further expansion after the valve has closed. An additional spring k, bearing against the casing of the apparatus, is provided to take the strain of such further expansion in conjunction with the packing tube s of the piston e. In one construction, Fig. 2, the rod g of the piston e is screw threaded to engage an adjusting- nut h, and the spring k is disposed between the nut h and a screw-cap i or a threaded sleeve l adjustable therein. In a modification, the spring k is disposed within the tube s between the piston e and a sleeve bearing against a screw plug adjustable in the cap i. In another modification, Fig. 3, the tube s is arranged below the piston e, its lower end being secured to a plug m screwed into the casing a. The plug is bored to allow the liquid to enter the tube s and to act on the piston e.
