Abstract
A valve apparatus for a fluid delivery system is disclosed having a valve housing including a fluid flow path, a valve member, a valve actuator operably connected to the valve member and configured to move the valve member between first and second positions, and a thermally-activated locking mechanism which provides the valve apparatus with an additional passive safety feature which will automatically lock and inhibit movement of the valve member upon reaching a pre-determined activation temperature.
Claims19
A valve apparatus for a fluid delivery system comprising:
- a valve housing having an inlet and an outlet which together form a fluid flow path across the valve housing;
- a valve member configured to move between a first position in which fluid is able to flow along the fluid flow path, and a second position in which the flow of fluid along the fluid flow path is restricted;
- a valve actuator operably connected to the valve member, said valve actuator being configured to move the valve member between the first and second positions;
- and
- a thermally-activated locking mechanism in thermal communication with the inlet and configured to inhibit movement of the valve member upon reaching a temperature above or below a pre-determined activation temperature.
