The present invention relates to a draining device for discharging the water contained in a fuel filter manifold, including a draining solenoid valve comprising a valve body (1′, 2′) provided with a draining channel (17′), a coil winding (10′), a piston (8′, 12′) arranged such as to be movable between a passive position for closing the draining channel (17′) and an active opening position allowing the water to be drained, the movement of the piston being controlled by the coil, characterized in that the valve body includes a first portion (1′) that is integral with the manifold of said filter, the coil (10′) and the electric circuit (3′) being embedded by molding in said first portion (1′) and a second portion (2′) removably mounted on the lower end of the first portion (1′) and provided with the draining channel (17′).
An emptying device designed to ensure the evacuation of water contained in a fuel filter collector, comprising an emptying solenoid valve including a valve body provided with an emptying channel, a coil winding, a piston arranged to be movable between a passive closed position of the emptying channel and an active open position allowing the emptying of water, the movement of the piston being commanded by the coil, wherein the valve body comprises a first part integral with the collector of said filter, the coil and an electric circuit being embedded by molding in said first part and a second part mounted removably on the lower end of the first part and provided with the emptying channel, wherein inside the coil, fixedly mounted, is a first cylindrical body made from a magnetic material followed by the piston made up of a second cylindrical body made from a magnetic material axially spaced apart from the first cylindrical body by a spring, and wherein said second magnetic body is provided with means making it possible to close the emptying channel in the passive position, wherein the second part of said valve body is provided with at least one air intake orifice, wherein said piston is arranged to close the air intake orifice in the passive position, and to open it in the active position, allowing the emptying of water and the intake of air.
