MEANS FOR DEFINING A FLOW PASSAGE IN A DRIPPER AND METHOD AND APPARATUS FOR ITS IMPLEMENTATION

摘要

A dripper unit adapted to be integrally bonded to an internal surface of a conduit. The unit being of the flat "boat-like" type and is made of solely two parts - an elongated body member formed on its one side that is intended to be affixed unto an inner wall of the conduit with an elongated water exit "pool"; and on its opposite side constructed with a throttle means and with a flow passage formed between them; and the second part is means for defining a flow passage between said means and said body. The dripper unit characterized in that the means for defining a flow passage is formed as an elongated flat thin sheet which is adapted to be bonded to the elongated body member while covering and therefore defining underneath, at least a flow-restricting flow path.
