Abstract
292,887. Bornefeld, G. Feb. 29, 1928. Check lift valves.-A safety cut-off device for gas conduits comprises two coaxial valves e, g mounted in a divided casing a, b arranged in the conduit, the valves being adapted to open in the direction of flow of the gas and being subjected to spring pressure so as to remain closed unless acted on by full gas pressure. The valve stems are tubular, the stem f of the valve g being guided within the stem d of the valve e, while the latter stem is guided in a sleeve k carried by a slotted disc c clamped between the parts of the casing. The spring h of the valve e is arranged outside its stem d and abuts against the end of the sleeve k, while the spring i of the valve g is arranged inside its stem f and is con. nected to a pin l fixed to the sleeve k and passing through slots in the stem d.
