摘要： A water sensor apparatus used in connection with a watering system. The water sensor apparatus includes a main housing comprising an inlet and an outlet. A valve mechanism is provided inside the main housing. The valve mechanism opens and closes the outlet of the main housing in response to a water level collected in the main housing and a water pressure entering the inlet of the main housing.

摘要： An enhanced pump assembly includes an impeller and volute casing designed to provide high operating pressures (“P”) and flow rates (“Q”) with low energy usage. The impeller has a central shaft carrying radially projecting curved primary vanes, and each primary vane also has a twist in the radial direction. Secondary impeller vanes define triangular connecting fillet-like wall segments connecting each primary vane to the impeller shaft. The casing of the pump has a slight spiral deviation so that the pump chamber's radial sidewall flares away from the swept area of the impeller's vanes to define a fluid outlet that contributes to higher P-Q performance, especially when pumping colder fluids.

摘要： An inexpensive, durable and efficient irrigation nozzle assembly is adapted to generate a specialized rectangular spray in a 3-jet fluidic circuit which generates a substantially planar rectangular spray from a confluence of three jets. The 3-jet geometry circuit has selected floor & taper features configured to create a customizable rectangular or triangular spray pattern. Depending on the throw desired, the nozzle assembly of the present invention can be configured with a second fluidic circuit to generate a flat fan to obtain various aspect ratios in a rectangular spray.
