Abstract

This invention refers to the construction of a filter for fluids, which opens for cleaning and closes to restore hydraulic pressure flow. These pressures are applied on a valve-piston configuration working together either axially, or by linkage system. The hydraulic pressures are adjusted manually, or by an automatic system, independent of input pressure and reverse pressure, or by an adjustable spring system in accordance with the waterworks pressure. Cleaning of the mesh is done by circular jets, generated by partial or complete flow divergence, moving axially. The filter opening time for cleaning is adjusted by regulating the flow rate of the fluid supplied at the top of the piston.
