Concealed sprinkler

A sprinkler comprising:

• a body having a proximal portion defining an opening and a distal portion defining an outlet, the body defining an internal passageway having an inlet and an outlet spaced apart along a longitudinal axis, the distal portion including an annular wall having an outer surface and an inner surface to further define a chamber distal of the outlet to house an internal component of the sprinkler;
• a cover plate assembly having a thermally responsive surface exposed to the chamber to actuate the sprinkler;
• a spacing member disposed between the annular wall and the cover plate assembly, the spacing member defining at least one aperture to provide communication between the chamber and an environment external to the sprinkler body such that the surface of the cover plate assembly is exposed to the external environment;
• and
• an escutcheon disposed about the annular wall, the escutcheon including a proximal end face and a distal end face, the escutcheon tapering in the proximal to distal direction toward the axis such that the distal end face of the escutcheon is located proximally of the spacing member.

• and
• means providing a plurality of apertures radially disposed about the longitudinal axis between the annular wall and the cover plate assembly, the apertures being configured to provide communication between the chamber and an environment external to the body such that the surface of the cover plate assembly is exposed to the external environment.
