ABSTRACT:
The invention concerns a filtration apparatus comprising a vessel divided into two chambers by a filter. An inlet orifice is provided in the vessel for liquid to be filtered, as well as an outlet orifice for the filtered liquid. A distributor device movable from the exterior of the vessel between a filtration position and a rinsing position is arranged in the vessel. In the filtration position of the distributor liquid is filtered into the first chamber, which the liquid leaves by passing through the filter, to penetrate into the second chamber, which it leaves, in the filtered condition, through the outlet orifice. In the rinsing position the liquid flows directly into the second chamber and passes through the filter in the reverse direction to penetrate into the first chamber which it leaves charged with impurities to be eliminated by an escape orifice arranged in the vessel.
