Abstract
A temperature-sensitive actuator is operatively connected to a valve by means of a spring-loaded linkage. The actuator causes a tensioned spring in the linkage to pass over center upon the occurrence of a predetermined temperature, thereby fully opening or closing the valve. The invention may be embodied in several forms including an automatic drain for water systems and a fire extinguishing system sprinkler control.
