  • Patent number: 6533557
    Abstract: This invention relates to a positive displacement pump which allows a liquid additive (such as liquid fertilizer) to be introduced into another liquid stream (such as water) and to be mixed in a constant proportion. One end of the pump can be connected to a faucet and the other end to a typical garden hose or other device. Water enters the pump through a faucet and is redirected (bent) by an upper stator which allows the water to rotate turbine vanes. The turbine is rotatably connected to a cam and the rotation of the cam moves pistons which allows liquid fertilizer to be drawn in from its reservoir. The liquid fertilizer flows through a tube and into one of two pistons. Then, the liquid fertilizer is dispelled through one of the exit tubes through the pumping action of the pistons. The water which was used to turn the turbine then combines with the liquid fertilizer as it comes out of the exit tubes and a water/fertilizer mixture is created.
