Automatic fire protection sprinkler assemblies having a trigger assembly with a thermally responsive element and a yoke that seats and facilitates heat flow over the thermally responsive element. The yoke includes an elongate support member with a central region centered between two end portions with linear portions extending between the central region and the end portions. The yoke defines a heat impact region in which the end of the trigger assembly is received and seated. The yoke also provides a lateral access to define a fluid flow path in fluid communication with the heat impact region to facilitate heat flow over the thermally responsive element.

Trigger assemblies for automatic fire protection sprinklers

A sprinkler guard for protection of a fire protection sprinkler to define one or more dimensional relationships between the guard and the sprinkler. The sprinkler guard includes a cage that defines an internal volume for housing operational components of the sprinkler including a fluid deflector and thermally responsive trigger. The sprinkler guard locates the deflector within the internal volume with an upper boundary of the cage spaced at a clearance distance from the fluid deflector and a lower boundary of the cage located between the deflector member and a fluid outlet of the sprinkler frame body. Affixed to the cage is a clamp assembly defining a hinged relationship for securing the sprinkler guard to the fire protection sprinkler and housing components of the sprinkler guard cage.
