Abstract: A pump assembly is provided that includes a gerotor pump and a manifold. An aspirating member is positioned between a pump inlet cavity in the manifold and a fluid reservoir. Fluid flow generated by operation of the pump is diverted by a flow control valve and accelerates as it passes between the aspirating member and the manifold. The resulting decrease in static pressure draws the fluid out of the reservoir where it mixes with the higher velocity fluid. As the combined fluid is slowed, the static pressure increases to “supercharge” the inlet cavity to improve the inlet fill and reduce cavitation. An inlet port in the gerotor pump corresponds to the inlet cavity in the manifold. The timing and geometry of an input port is optimized to prevent noise inducing pressure spikes while maintaining sufficient back pressure in the pump chambers to collapse entrapped vapor bubbles in the fluid.

Abstract: One non-propelled fluid resident in a reservoir is sucked into the flow path of a further fluid in transit propelled by fluid pressure. This is achieved by means of inducing a spiral cyclone path flow pattern in the propelled fluid to create a converging vortex with a turbulent mixing zone into a linear output transit line. The pressure at the vortex zone is reduced significantly from atmospheric to thereby produce a strong suction propellant force bringing the stored fluid into the turbulence mixing zone. The stored fluid is introduced axially in line with the cyclone axis and linear output transit line which receives thoroughly mixed fluids in substantially constant proportions over significant changes in pressure of the propelled fluid. Thus, the mixer device is ideal for dispensing insectides with a garden hose, detergents into a dishwasher, chlorine into a swimming pool, etc.
