Abstract
A flow path is provided for a drip emitter to reduce the supply pressure in a manner reducing the potential for the flow path to become obstructed and clogged. The path employs a central path with a predetermined size and a series of baffles with predetermined spacing. The flow path further includes a metering chamber and a diaphragm to compensate for changes in supply pressure and an outlet that facilitates self-flushing in conjunction with the operation of the diaphragm.
