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.

Abstract: A fire protection sprinkler is provided, including a body having an output orifice, a closure element or seal cap to seal a flow of fluid from the output orifice, and a thermally-responsive element positioned to releasably retain the seal cap. A clip, having a first portion and a second portion, is provided, the first portion being engaged with the closure element, and the second portion being in contact with the sprinkler body such that upon actuation of the fire protection sprinkler, the closure element rotates about a pre-determined axis and moves away from the sprinkler body to permit flow of fluid from the output orifice. In particular, the portion of the sprinkler body which the clip contacts is a detent provided on the wrench boss of the sprinkler.
