Abstract: The disclosure relates to a valve comprising a body defining at least an admission duct and an outlet duct for a fluid and receiving a valve member that is movable by means of an actuator member fastened to the body to move between a closed position closing the outlet duct and an open position leaving it open, the valve member having a central portion secured to a central portion of a substantially plane diaphragm that has a peripheral portion associated in leaktight manner with a support element secured to the body in such a manner as to co-operate with the support element to define a chamber, the valve member and the diaphragm being pierced by an opening providing permanent communication between the chamber and the outlet duct, the diaphragm being elastically deformable and being dimensioned to urge the valve member into its closed position.

Abstract: A valve having a body incorporating a filter The disclosure relates to a valve comprising a body defining a duct, a filter member defining filter passages and extending inside the duct, and a valve member mounted to move in the body between a closed position in which it closes the duct, and an open position in which it leaves the duct disengaged, the filter member comprising two filter portions having complementary profiles and secured respectively to the body and to a support element fastened inside the body in such a manner that the filter passages are defined between the facing portions of the complementary profiles.

Abstract: The present invention relates to a valve comprising a body (1) defining a duct (2), a filter member (16) defining filter passages and extending inside the duct, and a valve member (6) mounted to move in the body between a closed position in which it closes the duct, and an open position in which it leaves the duct disengaged, the filter member comprising two filter portions (17, 18) having complementary profiles and secured respectively to the body and to a support element (7) fastened inside the body in such a manner that the filter passages are defined between the facing portions of the complementary profiles.

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 vibrat

Abstract: A solenoid valve closure part comprising a seat and a solenoid coil, the valve closure part including the free end of a movable core within the hub of the coil, and further including an intermediate component capable of bearing against the seat and itself comprising a second seat, facing the first seat and of a lesser cross section than that of the first seat, the free end of the movable core being capable of bearing against the second seat and an elastic element being provided to press the intermediate component away from the first seat.
