摘要

Automatic pressurized water feeder, characterized essentially by the fact that it comprises an electric operation pump inserted in a line from the water tank, at whose outlet the pump communicates with a conduit provided with a non-return valve, after which a pump operating pressure switch is arranged as a function of the pressure created in the pipeline, in which a deformable chamber communicating at the same time with the general supply network is connected.
