Abstract: A sprinkler with a push-in connection includes a sprinkler frame, an operating element, and a sealing cap. The sprinkler also includes one or more sealing gaskets and a retainer. Each such sealing gasket is located at least partially within a groove in the sprinkler frame. The retainer is also at least partially located within a groove in the sprinkler frame. The retainer connects to an internal bore of an outlet of a fluid supply conduit when the sprinkler is installed in the outlet. The one or more gaskets seal against the internal bore of the outlet when the sprinkler is installed in the outlet. The retainer is a spring mechanism so that the diameter of the retainer is reduced when the sprinkler is inserted into the internal bore of the outlet, and the retainer maintains pressure against the outlet internal bore.

Abstract: A flexible dry sprinkler includes an inlet, an inlet seal assembly having a spring seal that compresses in response to a longitudinal load, and an inlet release unit. A flexible tube has an inlet end and an outlet end, and a flexible linkage extends through the flexible tube, and is connected to the inlet release unit. An outlet release unit is connected to the outlet end of the flexible tube and to an outlet end of the flexible linkage, and displaces the outlet end of the flexible linkage upon activation of the flexible dry fire protection sprinkler. A sprinkler body is connected to the outlet release unit, and has an outlet orifice sealed by an outlet seal assembly until ambient temperature reaches a predetermined temperature. When the ambient temperature reaches the predetermined temperature, translation of the flexible linkage in an outlet direction causes release of the inlet seal assembly.

Abstract: A flexible dry sprinkler has an inlet having an inlet orifice, an outlet, a flexible tube having a first end attached to the inlet and a second end attached to the outlet, an inlet seal for sealing the inlet orifice, whereby, when the inlet seal releases, fluid is permitted to flow from the inlet orifice to the outlet through the flexible tube, and a yoke positioned in the inlet, the yoke having a plurality of spaced-apart legs that permit the fluid to flow passed the yoke toward the outlet.

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.

Abstract: A flexible dry sprinkler includes a flexible tube, an inlet attached to an inlet end of the flexible tube, an inlet seal assembly configured to seal an inlet orifice of the inlet, and an inlet release unit configured to release the inlet seal assembly. The inlet release unit includes a frangible member configured to support the inlet seal assembly in the inlet orifice. An outlet is attached to the outlet end of the flexible tube, and includes an outlet orifice sealed by an outlet seal assembly having a thermally responsive element and an outlet seal. A flexible linkage extends between the inlet and the outlet through the flexible tube, and translates, when the outlet seal is released, a predetermined distance to operate the inlet release unit.

Abstract: A dry sprinkler has a casing tube having an inlet orifice and an outlet orifice. When the sprinkler is in a non-actuated state, an inlet seal assembly operatively seals the inlet orifice and an outlet seat assembly operatively seals the outlet orifice. A translating member extends through the casing tube between an inlet and an outlet. The translating member axially translates from a first position, in which the translating member retains the inlet seal assembly in a sealed state, to a second position, in which the translating member releases the inlet seal assembly, toward the outlet when the outlet seat assembly is released. The sprinkler has a nominal K-factor greater than 17 gpm/(psi)1/2. A difference between a cross-sectional area of the casing tube and a cross-sectional area bounded by an outer perimeter of the translating member is more than 30% of the cross-sectional area of the casing tube.
