Liquid filter equipped with an anti-leakage valve

Abstract

The invention relates to a liquid filter (6, 12), preferably a fuel filter, for a vehicle, said filter comprising a filter head (36) delimiting an inlet port (19) and an outlet port (21), a filter housing (30) which is to be screwed below the filter head (36) and which contains a filter element (32) centred on a central axis (X38), said filter element including a filter medium (38), a top end plate (42) and a bottom end plate (40). The filter housing (30) delimits a first volume for receiving a flow of liquid to be filtered, said first volume being delimited radially around the filter medium (38) and communicating with the inlet port (19) and a second volume for receiving a flow of filtered liquid, said second volume being delimited radially inside the filter medium (38) and communicating with the outlet port (21). The filter head (36) includes an anti-leakage valve (50) comprising a closing element (52) that is movable between a closed position in which it closes off the inlet port (19) and an open position in which the liquid can flow through the inlet port (19) and the filter (6, 12) further includes a pin (54) that is fitted on the filter element (32) and that is configured to penetrate inside the inlet port (19) so as to move the closing element (52) from the closed position to the open position.
