Abstract:
An anti-skipping sprinkler includes a frame defining a central longitudinal axis, the frame including a base portion defining an orifice, and first and second arms extending away from the base portion and joining at a lower end of the frame; a deflector located at the lower end of the frame; an orifice plug held over the orifice by a trigger element including a heat sensitive element; and an anti-skipping shield extending circumferentially around the heat sensitive element. The anti-skipping shield has an upper end and a lower end. The anti-skipping shield is open at the upper end and at the lower end to permit airflow to the heat sensitive element around the upper end and the lower end of the anti-skipping shield.
