Abstract: A low volume spray device for an irrigation system comprises upper and lower separately molded plastic members that are assembled before being installed on a fluid conduit. The two piece construction allows the upper or head member to be molded with a deflector portion having an exterior shape capable of forming a uniform spray pattern. The upper head member also has a lower tubular portion adapted to extend into the fluid conduit as well as around the lower member so that fluid pressure cannot act to separate the two members when in use.

Abstract: An improved apparatus and method are provided for irrigation systems such as automated sprinkler systems. A pre-assembled housing or valve box includes an inlet for receiving water and one or more outlets for distribution of water to other components in the irrigation system, and also includes manifolding and power and valve means for selectively controlling the flow of water from the outlets. Many of the manifold components are integrally molded with each other and provided in modular form so that the system can be relatively compact and can be customized into a variety of configurations. The manifold can consist of or include integrally formed or interconnected valve bases. The electrical power system includes a main terminal box with power lines leading to connectors adjacent each outlet, so that solenoid valves may be readily connected thereto and replaced as necessary. O-rings, non-conducting gel, and similar mechanisms are provided to ensure the water-tightness of the electrical connections. The box and its components may be manufactured, assembled, and installed more reliably, conveniently and economically than conventional irrigation systems, and may also be tested before installation.

Abstract: A drip irrigation emitter head assembly is described which comprises a body member having a tubular inlet portion adapted to connect with a water supply conduit. The body member includes a circular wall surrounding the tubular inlet portion forming a plurality of passages having open upper and lower ends. A flow control device in each passage forms a constricted emitter orifice. A cap connected to the body member covers both the tubular inlet portion and the surrounding upper ends of the passages. A removable filter retained between the cap and the body member filters water before it enters the passages at their upper ends. Flexible distribution tubes are connected to the lower ends of at least some of the passages in the body member for carrying fluid to preselected locations at their outer ends.

Abstract: Apparatus and methods include an improved filter and cleaning processes for same. A rotating cleaning element is actuated by vacuum pressure, and relatively precise controls ensure that all portions of the filter's surface are vacuumed cleaned during cleaning cycles. Longitudinal pressure on the rotating cleaning element is balanced to reduce wear and improve performance.

Abstract: The present invention is directed to a sprinkler apparatus and related methods for the distribution of fluid. The invention preferably includes a nozzle rotatably driven by a pressurized flow of fluid along a fluid path. The invention preferably includes a housing separating a magnetic drag coupling assembly from the fluid path. The coupling assembly preferably includes spaced apart magnets configured to exert an attractive force on each other to rotate one magnet in response to the rotation of the other magnet, and a resistive/drag force to oppose the continuous rotation of the nozzle. Pressure offsetting structures minimize or even neutralize the upward/downward forces that the flowing fluid otherwise would exert on the rotating shaft assembly.

Abstract: Apparatus and methods include an adaptor to establish a flow path through the side of a first piece of tubing (rather than the end of the tubing) into a second piece of tubing or other device. The adaptor includes a threaded head slightly larger than the hole in the side of the tubing into which it is to be inserted, and gripping portions to assist in forcing the threaded head through the opening. After the head has been inserted, a sealing element is tightened to prevent leakage. To join lay-flat tubing to drip tubing, the other end of the adaptor includes an annular barbed end; a sleeve member around the barbed end; and cooperating structures acting between the barbed end and the sleeve to move those relative to each other. Barb structures on the sleeve member cooperate with the barbed end to sealingly engage the drip-tubing end.

Abstract: A one-piece stabilizing stake adapted to be placed in a preselected ground area for retaining a flexible irrigation conduit. The stake has an elongated body with an upper portion for holding the conduit and an integral lower portion adapted to be driven into the ground. The upper stake portion has first conduit gripping members for holding the conduit end portion in a generally upright, vertical position and a second conduit gripping member on said body extending generally transverse on the body for holding the conduit substantially parallel to the ground area.
