Abstract: An irrigation apparatus comprises an in-line dripper insert having a support for attaching a micro tube to the dripper outlet. A fluid conduit in which the insert is placed has an aperture in line with the support. The support preferably comprises a projection for securing a micro tube thereto, a sleeve for securing a micro tube or a connector thereto, or a shoulder for supporting the attachment of a connector to the fluid conduit at the aperture. The dripper insert is secured to the inner surface of the fluid conduit and is contained entirely therein. After detachment of the micro tubes, the main fluid line may be easily reeled or otherwise handled. The internal dripper provides structural internal support to the main fluid conduit when external pressure is applied to the line, such as when a micro tube or a connector is forced against the fluid line to be connected thereto.

Abstract: A generally cylindrical or partially cylindrical body is intimately received in an irrigation pipe and has an outer surface in physical contact with an inner surface of the pipe. A flow-limiting labyrinth is formed by the outer surface of the body in combination with the pipe inner surface. A valve chamber is formed in the body and has four pairs of inlets and outlets forming an inlet retention valve and three labyrinth bypass valves. The first inlet is in fluid communication with the pipe interior and the first outlet is in fluid communication with the labyrinth inlet end. The inlet retention valve includes a first valve seat that surrounds the first inlet. Each bypass valve is connected between a respective section of the labyrinth and an external pipe outlet.
