drop a drop irrigation transmitter with an increase in the compensation of the pressure

摘要

an outer wall member, such as a wall or a tube connected with the pipe, an opening in communication with the outside of the pipe.an internal member is placed at the inside of the external member to separate the opening of the path of the fluid through the pipe.the internal member having an inner surface of at least a portion of an end in communication with the chamber, a fluid path in the pipe.the internal and external members define a labyrinth having an effective area sectionale crosses a creek at the end for receiving the fluid from the pressurizing pipe.and at the end of a flow path in communication with the opening of the pipe to the fluid.a plurality of channels coupling the intermediate portions of the labyrinth with the opening, and thus avoid the respective parts of the labyrinth.an elastic wall functioning as a valve.a barrier between the channel and the inner chamber and reacts against the pressure in the inner chamber to restrict the channel when the pressure exceeds a first set pressure of.nce. this prevents the fluid to a portion of the maze, raising the effective length of the labyrinte and reduce the pressure which takes place in the higher
