Abstract: A subsurface irrigation system includes one or more water distributing branches comprising a water emitting conduit and a water deflector member. The water emitting conduit extends through the area to be watered buried at an emitting depth below the surface of the area and is capable of receiving water at one end and emitting the water at a low overall flow rate along its length. The deflector member extends the entire length of the water emitting conduit generally below the level of the conduit and defines a deflecting area. The water deflector member comprises a layer of substantially water impermeable material and its position generally below the water emitting conduit allows it to block the downward flow of water in the water deflecting area. Deflecting the water below the water emitting conduit forces the emitted water laterally with respect to the conduit and capillary action in the soil draws the deflected water further laterally to saturate a significant area only to the depth of the root zone.

The whirlpool flushes debris from the chamber and pushes the ball around the chamber for a predetermined period of time. The ball then rests against the outlet to substantially obstruct the passageway out in a pressure-compensated manner.

Abstract: This invention relates to a device and method for converting low continuous liquid flow to a high intermittent and pulsating flow. They are especially adapted for operating sprinklers, shower heads and venturi pumps at low flow. Applicant has accomplished these objectives by introducing liquid at a controlled low rate of flow such as by the use of pressure compensating drippers in a liquid supply line, thence into a chamber which is somewhat expansible in volume and increasing pressure therein while restricting the outflow of the liquid until pressure created by introduction of such liquid is sufficient to eject the liquid intermittently at a higher flow and over a greater area. This is achieved by utilizing a pressure responsive check valve in the liquid exit and more particularly by utilizing a check valve designed for quick response to create a water hammer effect.
