Patent abstract
A dry sprinkler assembly includes a housing, a sprinkler head assembly with a sprinkler head and a trigger assembly, and an actuator assembly. The actuator assembly has a sealing subassembly for sealing the inlet port of the housing and 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 its closure at the outlet opening. The sealing subassembly moves in a linear path substantially parallel with the central longitudinal axis of the housing when releasing the sealing of the inlet port wherein the flow of fire suppressant through the inlet port and into the fluid flow passage is substantially unimpeded.
