摘要： The telescoping pop-up sprinkler includes a telescoping piston assembly that allows the piston assembly of the pop-up to extend upwards at a greater height than the length of the pop-up sprinkler body. The telescoping pop-up sprinkler has a main body with a piston assembly that includes two or more pistons that engage internally with one another, with stops provided at one end of each piston to limit the stroke of each piston. Multiple internal seals are provided to prevent the bypassing of water around the outer diameter of each piston.

摘要： A pressure activated seal includes a main wall, side walls connected to the ends of the main wall, and flexible flaps connected to the side walls. The main wall, side walls, and flexible flaps define a main chamber adapted to receive fluid pressure for activating the pressure activated seal to form a seal between opposing adjacent surfaces. The pressure activated seal can be placed between concentric tubes or between adjacent plates, with one of the tubes or plates including one or more orifices leading to the main chamber to allow fluid pressure to activate the pressure activated seal to form a seal between the opposing adjacent surfaces of the tubes or plates.
