ABSTRACT:
The present invention related to a filter consisting of a stack 4 of elements 5 comprising one cylindrical side and each element consisting of several isolated sections 23-24 and provided with orifices 35 for communication of its sections with the circumferences of the element and with a rotary distribution valve 37 mounted to rotate coaxially with the cylindrical side and comprising a chamber 22a for the isolation of a first section 23 from any element of the other sections, communicating with this first section through a port of the distribution valve.
The form of the port 22a and the layout of the orifices 35 are such that the first sections 23 of only one part of the elements are in communication with the chamber 22a.
One application is the manufacture of a filter of small size and high efficiency.
