Abstract

172,335. Tolmer, L. J. C. Dec. 4, 1920. [Convention date]. Fluid-actuated valves.-To equalize the pressure through a steam heating system for railway carriages, a valve device is fitted between the steam main and each radiator, the device comprising a piston 6, having a sleeve extension with radial ports, which, when the pressure in the radiator rises above a certain limit and forces the piston outwards against the pressure of a weight or spring 7, slides over the circular admission groove 4, through which the steam passes from the inlet branch to the branch 3 connected to the radiator. The piston is formed with expansion grooves. The compression of the spring is regulated by a screwed plug 11 in a cap 10 on the valve casing. A pipe 13 leads off water of condensation from the back of the piston. In a modification having a piston pressed inwards by a weighted lever, a cap is soldered over the piston to prevent dust &c. from entering the device
