Abstract:
A dry sprinkler includes a flexible tube section that maintains a pressurized fluid, such as a liquid antifreeze solution, between a first end and a second end. A first seal prevents fluid from a supply line from entering the flexible tube section. The first seal is maintained in a sealed position by a pressure of the pressurized fluid. A sprinkler head is coupled to the second end of the flexible tube section, and includes a frame, an output orifice, a deflector, a second seal that seals the output orifice, and a thermally responsive element configured to maintain the second seal in a sealed position when the thermally responsive element is in a non-responsive state. A differential pressure controller maintains a ratio between the pressure of the pressurized fluid in the flexible tube section and a pressure of a supply fluid in the supply line to at least a certain ratio.

Claim (Index 19):
A dry fire protection sprinkler according to  claim 18 , wherein the fitting has an inner wall with an annular flange, and the annular plug of the inlet seal assembly extends into both the spring washer and the annular flange.
