The invention provides an electromagnetic actuator comprising at least two coils () associated with ferromagnetic cores () and disposed facing each other, and a moving element () extending between the coils () and associated with an actuator rod (), the coils () comprising conductors () with ends () extending transversely to an axis () of the coils () and fixed directly to pins () carried by a connection plate () fixed on one side () of the coils () and including a connection circuit () providing connections with a connector () also carried by the connection plate ().

Electromagnetic actuator

The electromagnetic valve actuator has an armature ( ) of ferromagnetic material fixed to the stem of the valve, springs are provided to hold the valve at rest in a middle position between a fully open position and a closed position, and a single coil ( ) is mounted on a ferromagnetic circuit. In combination with the armature, the magnetic circuit presents two stable magnetic flux paths both of which correspond to an airgap of small size.

Electromagnetic valve actuator

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

Solenoid bleed valve for a device for the disposal of vapours

The invention concerns a valve controlling device with linear displacement along an axis comprising a number of actuators equal to that of the valves. Each actuator has a ferromagnetic blade fixed to a valve push rod and at least a return spring whereof one end is supported against the rod and the other end is supported against fixed anchoring means, adjustable in position relative to a housing of the actuator. A passage is provided between the actuators of the two adjacent valves to allow through an adjusting tool.
