<p>A device for disabling flow shut-off selector members (11) for percolating filter systems (1), wherein the filter system includes a seat (4) for housing a replaceable filter cartridge (2) and a flow shut-off selector member designed to shut off the flow filtered by the cartridge during a required passage (10) of the flow through the seat, the selector member includes a valve for shutting off the required passage with a plug (13) and a projection (14) for actuating the plug for the purpose of opening the valve when the actuating projection interferes with a counter-projection (30, 40, 50, 60), and the device comprises the counter-projection in a form structurally independent of the cartrige and is shaped in such a way that the counter-projection can be inserted into the required passage and retained therein in a condition of interference with the projection of the plug in order to keep the latter in the open position regardless of the presence or absence of the catridge in the seat.</p> |
