ABSTRACT:
A suction pressure regulating valve automatically maintains the suction pressure of a swimming pool cleaning system to be consistent with the optimum range of water suction pressure when the valve is used with suction type automatic swimming pool cleaners. The valve is a water immersed device which permits water to bleed through an orifice, which orifice opens in proportion to suction pressure within the valve. The valve has a conical body which readily adapts in line with the flexible hose that connects the swimming pool filter system with the suction type automatic swimming pool cleaner. This type of pool cleaner moves about the sides and the bottom of a swimming pool, continuously cleaning those surfaces. The valve orifice is protected from air incursion by an anti-vortex plate when the valve is near the surface of the pool.
