  • Skimmer with flow enhancer
    Patent number: 4818389
    Abstract: A skimmer for skimming water from a swimming pool or spa is provided with entraining means for entraining additional water from the pool or spa to thereby increase the flow of water into and out of the skimmer. The entraining means includes two nozzle members which cooperate with each other to jet an entraining stream of water through the skimmer. The skimmer is also provided with isolating means for isolating the entraining stream of water from the rest of the water flowing through the skimmer. The isolating means includes actuating means for selectively actuating and deactuating the isolating means such that the skimmer can be operated at a normal flow rate when the isolating means is actuated and at an increased flow rate when the isolating means is deactuated.
