A dry sprinkler assembly comprises a housing having an inlet end, an outlet end, a fluid flow passage extending from the inlet end to the outlet end, and a central longitudinal axis along the fluid flow passage. The inlet end is adapted for mounting to a fluid supply pipe and has an inlet port axially aligned with the central longitudinal axis of the housing for fluid communication with the fluid supply pipe. A sprinkler head assembly has a sprinkler head and a trigger assembly, the sprinkler head being in fluid communication with the fluid flow passage and having an outlet opening. The trigger assembly substantially closes the outlet opening and releases the closure during a fire condition. An actuator assembly has a sealing subassembly sealing the inlet port. The actuator assembly is operatively coupled to the trigger assembly such that the sealing subassembly releases the sealing of the inlet port in response to the trigger assembly releasing the closure at the outlet opening. The sealing subassembly moves in a linear path substantially parallel with the central longitudinal axis when releasing the sealing of the inlet port, and wherein the actuator assembly comprises a plurality of collinear tubular members, each of the tubular members having a passage, the passages forming the fluid flow passage. A first of the tubular members comprises a first outwardly flared conical section extending radially outward from a cylindrical body section of the first of the tubular members, a second of the tubular members being adjacent to and aligned with the first of the tubular members and including a diameter reducing conical section disposed adjacent to and aligned with the cylindrical body section of the first of the tubular members.
