Controllable emitter
First Claim
1. A controllable emitter of an irrigation apparatus including a drip line having pressurized fluid therein, the controllable emitter comprising:
- a container coupled to the drip line, the container being formed to define an interior and including an inlet through which the pressurized fluid is receivable in the interior from the drip line and an outlet through which the pressurized fluid is exhaustible from the interior;
a single magnetic stopper, which is normally disposable in a first position such that the single magnetic stopper prevents a flow of the pressurized fluid through the outlet and which is actively disposable in a second position such that the single magnetic stopper permits the flow;
a controllable actuator configured to generate a magnetic field operable to urge the magnetic stopper to move from the first position to the second position; and
a frusto-conical support element having a longitudinal length that exceeds a corresponding length of the single magnetic stopper and a narrow end and a body tapered toward the narrow end, the narrow end being coupled to the inlet such that a portion of the magnetic stopper is partially disposed in the interior of the container when the single magnetic stopper is in the first position, and in the second position at least a portion of the single magnetic stopper is partially disposed in the interior of the frusto-conical support element such that the body is disposed to maintain a lateral position of the magnetic stopper.
