ABSTRACT:
A regulating control valve used with automatic pool cleaners in swimming pools is disclosed. A cap serves as a closure for the opening in a relief chamber and has a relief port therethrough. On the underside of the cap and surrounding the port there is a hollow boss which serves as a valve seating against which a relief valve within the chamber seals. There is a bleed opening between the cap and the relief valve which is permanently connected to the main water passage. The bleed passage is formed either by an eccentric enlargement to the port or by a cut out in the boss.
