Abstract:
1. An automatic fire protection sprinkler comprising: a sprinkler body having an axially extending passageway with an outlet through which a fire suppressant fluid flows; a deflector carrier axially moveable relative to the body between a first position distal of the outlet and a second position distal of the first position, the deflector carrier having a radially extending leading edge facing the outlet and a pair of mounting locations distal of the leading edge; a pair of guide pins reciprocally coupled to the sprinkler body on opposite sides of the outlet for movement between a first retracted position and a second extended position and having axially opposite first and second ends, the pair of guide pins coupled to the deflector carrier at the pair of mounting locations, the pair of guide pins moveably coupling the deflector carrier to the sprinkler body between the first retracted position and the second extended position; and a deflector attached to the deflector carrier and moving with the deflector carrier between the first and second positions, the deflector distributing fire suppressant fluid thereon into a flow distribution pattern, wherein the deflector carrier maintains the deflector distally spaced away from and downstream of the pair of guide pins and the leading edge is closer to the outlet than the mounting location in both of the first and second positions.
