Claim 13:
14. A flexible dry sprinkler comprising:
an inlet having an inlet orifice and an inlet seal;
an outlet;
a flexible tube having a first end attached to the inlet and a second end attached to the outlet;
a strut positioned axially within the inlet, the strut pressing against the inlet seal to seal the inlet orifice; and
a horizontally-positioned bar coupled to the strut and pressing against the inlet seal, whereby, when the bar is caused to move, in an activated state of the flexible dry sprinkler, pressure from the strut against the inlet seal is removed, thereby releasing the inlet seal and permitting fluid to flow from the inlet orifice to the outlet through the flexible tube.
