Abstract

293,930. Royer, G. G. May 3, 1927. Thermostats.-A thermostat comprises a container a filled with an expansible fluid and having a plunger b passing through a bi-conical packing c against which a washer d is pressed by a spring e. The end b' of the plunger carries a nut k abutting against a spring l. On expansion due to rise of temperature, the container a moves to close the port e, and any further expansion is then absorbed by a movement of the plunger against the spring l, so that no damage is caused. In a modification, Fig. 3, the container a is normally fixed and the valve G is carried by the plunger. Any expansion after the valve closes is absorbed by movement of the container against a spring m. At the same time, the contacts n, o are closed, and an alarm signal operated. The springs l, m are sufficiently strong to resist deformation under normal working.
