The Reliable Automatic Sprinkler Co. Inc.

A unibody air maintenance device includes a body that is a single, integral component. The body has an inlet and an outlet. The inlet receives a pressurized gas and the outlet directs the pressurized gas to a dry fire protection system. A regulator is disposed within the body and maintains a pressure of the pressurized gas at a set pressure. A check valve is disposed within the body and opens to allow the pressurized gas to flow from the inlet towards the outlet and closes to prevent the pressurized gas from flowing from the outlet towards the inlet. A three-way valve is disposed within the body downstream of the inlet and upstream of the regulator. The three-way valve allows the pressurized gas to flow towards the regulator in a regulate position and to prevent the pressurized gas from flowing through the unibody air maintenance device in an off position.

A foam-water fire sprinkler includes a nozzle, a shroud body, an agitator, and a deflector. The nozzle defines a nozzle passage that receives a foam-water solution therein. The shroud body defines a shroud passage that receives the foam-water solution from the nozzle passage. The agitator is positioned within the shroud passage, and has a rounded agitator portion and a straight agitator portion that extends from the rounded agitator portion. The foam-water solution impinges on the agitator at the rounded agitator portion to aspirate the foam-water solution with air to generate foam. A portion of the foam-water solution separates from the agitator at the straight agitator portion. The deflector deflects the foam-water solution and the foam to generate a spray pattern of the foam-water solution and the foam at a coverage area.

A fire protection nozzle includes a body having two frame arms having proximal ends connected to an outlet of the body, and distal ends, the two frame arms defining a frame arm plane, and a junction formed by the distal ends of the frame arms, the junction including a central bore and an outer wall. A deflector is mounted to the body, and includes a planar member having a mounting hole in a center of the planar member to receive the outer wall of the junction, and a plurality of slots on a periphery of the planar member. The plurality of slots includes first slots, second slots, third slots, and fourth slots.
