ABSTRACT:
A fluid flow regulator useful with swimming pool suction cleaners includes a flow passage conduit for connection between a suction pump and the pool cleaner. A flow bypass conduit is connected to the flow passage conduit for injecting an ambient fluid into a bypass flow passage. A valve operates within the bypass flow passage with a spring carried entirely within the bypass passage for urging the valve toward a seated position. An adjustment knob acts on the spring for modifying a biasing force on the valve urging the valve toward the seated position in opposition to a pressure from a fluid flow within the flow passage urging the valve to the open position.
