Abstract:
A system for supplying and withdrawing water comprising:a water passage having a first end adapted for use selectively with an external apparatus separable from the system; means connected with a second end of the water passage for generating a fluid pressure differential in two modes in the water passage between the first and second ends thereof; means for selectively establishing water communication of the water passage with a water source, or with a place of water drainage, the means for establishing water communication being connected with the means for generating a fluid pressure differential, in order to supply water to the apparatus through the water passage, or to withdraw water from the apparatus and deliver the withdrawn water to the place of water drainage through the water passage, during different periods of time; and a main controller associated with the means for generating a fluid pressure differential and with the means for selectively establishing water communications, the main controller controlling the operation of water supply and withdrawal.
