Abstract: A sprinkler assembly includes a body, a support, which extends from the body, and a closure device that releasably closes the discharge opening of the body. The sprinkler assembly further includes a trigger that releasably holds the closure device at the discharge opening. A flow shaper is mounted to the support and the support is adapted to allow the fluid flowing from the discharge opening, when the closure device is released, to pass through the support substantially unimpeded by the support and the flow shaper is adapted to reshape the flow of fluid as it flows through the support. The flow shaper is formed from a plate having an elongated portion having first and second side edges and first and second ends with at least one tab extending from the first side edge. The elongated portion is formed into a ring shaped body and the at least one tab is bent radially inward toward a center of the generally ring shaped body.

Abstract: An automatic sidewall sprinkler includes a body, a deflector, a closure member, and a trigger. The deflector is movably mounted between a retracted position wherein at least a portion of the deflector is recessed within the body and an extended position for dispersing pressurized fluid. The deflector includes at least two horizontal deflecting surfaces for directing the fluid outwardly and downwardly from the sprinkler. The trigger applies a biasing force to urge the deflector in the retracted position and to urge the closure member to close the outlet. Upon detecting a temperature associated with a fire, the trigger releases the biasing force whereby the pressurized fluid moves the closure member off the outlet and moves the deflector to the extended position. Preferably, the trigger includes an ejector member which urges the trigger to eject outwardly from the body to improve release of the trigger from the sprinkler.

Abstract: An automatic flush sprinkler side wall sprinkler assembly includes a sprinkler body, a deflector, a closure member, and a trigger assembly. The deflector is movably mounted to the sprinkler body between a retracted position wherein at least a portion of the deflector is recessed within a cavity of the sprinkler head body and an extended position wherein the deflector is spaced from an outlet opening of the sprinkler head body for dispersing pressurized fluid which flows from the outlet opening. The deflector includes at least two horizontal deflecting surfaces which are positioned spaced from and generally parallel to a direction of flow of the fluid from the outlet opening for directing the flow of fluid outwardly and downwardly from the sprinkler assembly and, further, are provided on a common side and spaced from a central axis of the deflector. The closure member is positioned between the deflector and the outlet opening for sealing the outlet opening.
