Abstract: A sprinkler includes a body defining (a) a passage having an inlet and extending along a longitudinal axis and (b) an outlet fluidly coupled to the passage. The sprinkler includes a seal engaging a button and the body to fluidly seal the inlet from the outlet. A link and lever assembly includes a first lever and a second lever engaging the button. The first lever and the second lever each include (a) a leg positioned near a base end of the lever and extending outward from the longitudinal axis, the leg defining an engagement surface, (b) a head positioned near a tip end of the lever, and (c) a main body extending from the leg to the head. A fusible link limits movement of the heads. The engagement surfaces each engage a surface of the body to limit movement of the button along the longitudinal axis.

Abstract: A sprinkler includes a body defining (a) a passage having an inlet configured to be fluidly coupled to a source of fire suppressant fluid, (b) an outlet fluidly coupled to the passage, and (c) a compression pin aperture extending from an outer surface of the body to the passage and configured to receive a compression pin, a button received within the passage, and a seal engaging the button and the body to fluidly seal the inlet from the outlet. The compression pin aperture is positioned such that the compression pin engages the button to force the button against the seal when the compression pin is inserted into the compression pin aperture.

Abstract: A sprinkler assembly includes a body defining an inlet, an outlet, and a fluid passage extending along a longitudinal axis between the inlet and the outlet. A guide pin aperture is defined by at least one of the body or a bushing coupled to the body. The sprinkler assembly further includes a deflector slidably coupled to the body. The deflector includes a deflector body coupled to a guide pin. The guide pin includes a shaft portion extending through the guide pin aperture and a shoulder that is wider than the shaft portion and configured to engage at least one of the body or the bushing to limit movement of the deflector body away from the body.
