Abstract
A water powered sump pump has a flow control apparatus connected to a source of water under pressure and to a suction generator. Water from the flow control apparatus flows through a nozzle in the suction generator, creates a pressure drop, suck water in from a sump, and discharge water through a discharge line. The control apparatus has a variable pressure chamber and a constant pressure chamber. The constant pressure chamber is connected to a source of water under pressure and to the suction generator. A diaphragm separates the two chambers and opens and closes a passage between the water source and the suction generator. An orifice connects the two chambers. A bleed valve opens and closes the variable pressure chamber. A spring biased arm of an actuator assembly is biased in one direction to open the bleed valve, drop pressure in the variable pressure chamber, move the diaphragm and open the passage which permits flow to the suction generator. Spring biased arm is biased in another direction to close the bleed valve and move the diaphragm to stop flow to the suction generator. A control arm controls the direction the spring biased arm is biased. An adjustable float moves the control arm in response to changes in sump water level.
