Abstract: A sprinkler assembly including a pressure regulator and a flow stop element combined in a single assembly. In one embodiment, the sprinkler includes a sprinkler body in fluid communication with a water supply to provide water to the sprinkler, a riser movably mounted in the sprinkler body and in fluid communication with the sprinkler body such that the riser rises up and out of the sprinkler body when water is provided to the sprinkler, a nozzle assembly mounted on a top end of the riser and in fluid communication with the riser; and a regulation element mounted in the riser and in contact with a portion of the nozzle assembly. The nozzle assembly holds the regulation member in an open position to allow flow of water to the nozzle assembly and to maintain a substantially constant water pressure in the nozzle assembly.

Abstract: A pressure regulator for use in a sprinkler assembly including a riser and a sprinkler basket includes an outer sleeve mounted in the riser at an inlet thereof and a pressure responsive member, movably mounted in the outer sleeve and movable from an open position allowing flow of water between the top surface of the filter basket and the bottom edge of the pressure responsive member and up the riser and a closed position where the bottom edge of the pressure responsive member contacts the top surface of the filter basket to prevent water from flowing. The pressure responsive member is biased in the open position and moves into the closed position when downstream water pressure exceeds a predetermined value.
