ABSTRACT:
Automatic swimming pool cleaning systems are disclosed. The systems include an automatic swimming pool cleaner incorporating one or more curved wipers protruding from its lower surface. The wipers and flat bottom of the cleaner induce a vortex as fluid flows to its central inlet, entraining debris in the flow. A fluted throat surrounding the inlet additionally assists the interior of the base of the cleaner in retaining debris when opened for cleaning, additionally providing an improved flow path for enhanced debris pick-up. Alternate embodiments incorporate a rudder and resistance plate for enhancing movement of the cleaners in the presence of obstacles. Also disclosed is a valve useful for controlling and indicating the rate of fluid flow to a cleaner. Included within the valve is a plunger attached to a spring, with the spring force opposing fluid flow through the valve. Flow sufficient to overcome the spring force compresses the spring, however, thereby moving the plunger within the tube and providing a dynamic indication of the rate of fluid flow. A diffuser and fluid release ports permit the valve to be adjusted to achieve a desired flow rate.
