Abstract

This invention includes modifications to the Patent No 1000121. The first modification involves the addition of a membrane and a chamber into the continuous, pressure-reducing conduit of the drip irrigation hose described in the patent No 1000121. With this addition the water amount is self-adjusted so as it is the same through all the outflow holes across the hose. The second amendment involves an alternative production method and additional, preferred structures of the drip irrigation hose. Firstly, the main hose is produced by using a special corrugator and its entire outside surface or part of it is appropriately formed so that one or more conduits are uncovered. Then, either one or more conduits are covered with a strip or the entire hose is covered with a mantle for its final configuration.
