Abstract
A solenoid purge valve for a device for removing vapor, the valve having: a case (1, 2) with vapor inlet and outlet orifices (3, 4); an electromagnet coil (6) mounted in the case; a magnetic armature (21) situated facing one end of the magnetic core (11) of the coil (6) and movable axially between two positions; a valve seat (20) mounted in leaktight relationship with the outlet orifice (4) of the case; and a closing valve member (25) secured to the moving armature (21), the valve member (25) being pressed against its seat (20) and spaced apart therefrom respectively when the moving metal armature (21) is in each of its two positions; the seat (20) is supported by the coil (6) and has a tubular extension (17) secured thereto and engaged coaxially in the outlet orifice (4), possessing a smaller diameter, an O-ring (19) being interposed radially between the tubular extension (17) and the outlet orifice (4), whereby the valve member and its seat are highly decoupled from the case from the point of view of vibration.
