Abstract
A dry fire protection sprinkler has an inlet seal assembly to seal an inlet orifice. A spring seal compresses in response to a load. An inlet release unit releases the inlet seal assembly. A flexible tube has an inlet end connected to the inlet release unit. A flexible linkage extends through the flexible tube, and has an inlet end connected to the inlet release. An outlet biasing portion is connected to an outlet end of the tube and an outlet end of the linkage, which displaces upon activation of the sprinkler. A sprinkler body is connected to the outlet biasing portion, with an outlet seal assembly to seal its outlet orifice. When ambient reaches a predetermined temperature, the outlet seal assembly releases from the outlet orifice, and the outlet biasing portion displaces the linkage, causing the inlet of the linkage to operate the inlet release unit, releasing the inlet seal.
