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.

In combination with a swimming pool filter system joined in fluid communication with a suction type automatic pool cleaner by a swimming pool cleaner hose, suction regulator valve apparatus including: a first portion of the hose; a second portion of the hose; a body of rigid molded plastic, the body having an exterior and a hollow interior and having a generally conical shape; an open male end on the body, the male end insertable into the first portion of the hose; an open female end on the body which is larger than the male end, the second portion of the hose insertable into the female end; a cup-shaped cap removably attached to the body, which cap is at least partially comprised of material capable of deforming readily under pressure; a deformable planar top of the at least partially deformable cap; an orifice formed of at least one slit in the planar top, the orifice capable of opening and closing as the deformable cap top flexes at least partially out of its plane in response to changes in water pressure differential between the interior and exterior of the body; and an anti-vortex plate of rigid molded plastic on the exterior of the body, the anti-vortex plate having a panel oriented a fixed distance away from the planar cap top and parallel thereto to prevent air vortices from entering through the orifice.
