Abstract
An agricultural drip emitter optionally includes an elastomeric having a flow restriction. Flow through the emitter, when deployed inside an irrigation hose, is optionally regulated by pressure-responsive deformation of the elastomer. The flow restriction optionally includes under-tooth bypass spaces located between a base and a sequence of baffles. Some implementations also include a rigid polymer component. Optionally, a thermoset elastomer component is mechanically interlocked with the rigid component. The elastomer component and the rigid component are optionally molded as a unitary part by two component injection molding. Optionally, in the molding process, a divider initially divides the mold into two cavities. After forming the first component, the divider is optionally repositioned for forming the second component with an interface to the first component. The sequence of baffles is optionally formed by elastic stripping from an undercut mold.
