Abstract
An emitter for use in irrigation comprising a housing and a flow restrictor in the housing. The housing has an inlet which can be connected to a source of irrigation liquid and an outlet. The flow restrictor reduces the pressure of the irrigation liquid to provide drip or trickle flow at the outlet. A spike flow inhibitor is provided in the housing for substantially preventing flush flow through the housing upon initiation of the flow of irrigation liquid through the housing. The flow restrictor is responsive to at least a predetermined reduction in pressure of the irrigation liquid at the inlet for causing flush flow through the flow restrictor.
