Definitions
- the present invention relates to electromagnetic devices comprising a coil and a movable element under the effect of the magnetic field of the coil, and more particularly an electromagnetic device incorporating connection means.
- Vehicles with internal combustion engines are conventionally fitted with an activated carbon filter called a canister which absorbs and retains fuel vapors from the tank.
- the canister is connected to the engine intake via a purge solenoid valve which is closed when the engine is stopped and which opens so as to allow the canister to be purged when the engine is running. The excess vapors in the tank are thus evacuated towards the engine or they are burned.
- the activation of the canister purge valve depends on the manufacturer's purge cycles.
- an electromagnetic device comprising:
- the fuel vapor outlet pipe being disposed in an intermediate box.
- the intermediate box is arranged in the extension of the first box.
- the fuel vapor outlet pipe extends inside the intermediate box and opens out on the outside of the pipe by a face different from that where it enters the intermediate box.
- the fuel vapor outlet pipe is divided into two pipes.
- the device comprises at least one additional element connected to one end of the conduit.
- the device comprises two safety valves.
- the device comprises a filter arranged on the path of the fuel vapors upstream of the electromagnetic system.
- the two conduits form an angle of 90 ° C with each other or an angle of less than 90 ° C.
- the invention also relates to the use of the device according to the invention in a motor vehicle.
- FIG. 1 is a schematic representation of a longitudinal section of a device according to the invention, 2a) open solenoid valve, 2b) closed solenoid valve,
- FIG. 2 is a schematic representation of a longitudinal section of two embodiments of a device according to the invention 2a) diaphragm cooperating with lug, 2b) diaphragm with enlarged head,
- FIG. 3 is a schematic representation of a longitudinal section of two embodiments of a device according to the invention 3a) conduits at an angle of 90 ° C, 3b) conduits with an angel ⁇ 90 ° C,
- FIG. 4 is a view of the filter of the device according to the invention.
- the present invention relates to an electromechanical device 10, and more particularly to a canister purge solenoid valve 10 comprising at least one fuel vapor outlet pipe, with a connector, integrated in a solenoid valve housing.
- the objective of this integration is to allow connection with at least one other element such as a valve, or a sensor, or another element, without additional connection, and thus without additional emission.
- the device 10 includes a fuel vapor inlet conduit 20 connected to a fuel vapor circulation conduit arriving from a fuel tank, and a vapor vapor outlet conduit 30 fuel.
- the device 10 comprises at least one connector 50 for its electrical connection.
- the materials of the device 10 are chosen to resist hydrocarbon vapors, in particular petrol.
- a first housing 61 of the device 10 internally houses an electromagnetic system 60.
- the latter comprises a fixed core 62, tubular of axis X, made of a soft ferromagnetic material such as for example iron or ferromagnetic steel.
- the electromagnetic system 60 comprises a coil 63 which extends around the fixed core 10 to generate within it a magnetic field when it is electrically powered.
- the coil 63 is for example made of insulated copper wire, in particular enameled.
- the system also includes an element movable along the X axis under the effect of the magnetic field generated by the coil 63, this movable element being in the form of a plunger core 70, made of a ferromagnetic material, axially movable along the X axis inside the fixed core 62.
- the plunger core 70 is inside the fixed core, in the example considered, and the flow, which is preferably gaseous (fuel vapors in this case), takes place in contact with it when it is open.
- the plunger core 70 is made of a soft magnetic material, which loses its magnetization when the magnetic field of the coil ceases, as does the fixed core 62.
- the plunger core 70 comes to bear against a valve seat provided with an orifice 23 through which the fuel vapors circulate when the device is open.
- a return spring 80 ensures the return of the plunger core 70 to its rest position, closing the outlet conduit, in the absence of electrical supply to the solenoid valve.
- the inlet duct 20 has an inlet opening 21 through which the fuel vapors arrive and an outlet opening 21 through which the fuel vapors are discharged, upstream from the orifice 23 of the valve seat.
- the electromagnetic system 60 is extended by the conduit 30 for the outlet of the fuel vapors.
- This conduit has at its base a nozzle.
- This nozzle is used to optimize the flow and flow of the evacuated fuel vapors. It is therefore the nozzle which extends in the form of the conduit 30 for the outlet of the fuel vapors.
- the fuel vapor outlet conduit 30 is disposed in an intermediate housing 71.
- This intermediate housing 71 is arranged in the extension of the first housing
- the intermediate housing 71 is fixed to the first housing 61.
- the fixing is carried out by bonding welding or any means compatible with the use of the device.
- the conduit 30 for the outlet of the fuel vapors extends inside the intermediate housing 71 and opens out on the outside of the conduit by a face 710 different from that 711 where it enters the case 71 intermediate.
- the conduit 30 opens to the outside of the conduit by a face 710 opposite that 711 where it enters the intermediate housing 71.
- the conduit 30 opens to the outside of the conduit by a face adjacent to that 711 where it enters the intermediate housing 71.
- the term penetrate described here the end of the conduit 30 which is in contact with the electromagnetic system 60 of the conduit 30, and which is therefore located in the intermediate housing 71.
- the conduit 30 for the outlet of the fuel vapors has a branch 40. More specifically, the conduit 30 for the outlet of the fuel vapors is divided into two conduits 40, 300. The second conduit 40 opens onto a faces adjacent to one of the two inlet faces 711 and outlet 710 for the outlet of the fuel vapors.
- the intermediate housing 71 has a single opening.
- the intermediate box 71 thus allows the support of the conduits 30, 40 and the associated connections 90.
- this additional element 90 is a safety valve illustrated in FIGS. 1 to 3.
- the device 10 comprises two safety valves illustrated in FIGS. 1 and 2a, 2b.
- this additional element 90 is a visible connector, FIGS. 2a and 2b, for any other element compatible with the device.
- the two conduits 40 and 300 are arranged perpendicular to one another. More precisely, they form an angle a of 90 ° C or different from 90 ° C with each other.
- the two conduits are arranged so as to form an angle a 'less than 90 ° C. Such a configuration allows better throughput.
- the angle a, a ′ being the angle formed by the two conduits 300, 40 coming from the conduit 30 for the outlet of the fuel vapors.
- an additional element 90 when an additional element 90 is a safety valve, the latter comprises a diaphragm 91 visible in FIGS. 2 a and 2b.
- the diaphragm is configured so as to be held in place in the body 94 of the valve during the assembly of the safety valve 90.
- the diaphragm 91 includes a recess 92 cooperating with a lug 95 formed in the valve body. The diaphragm is thus blocked during assembly.
- the end 93 of the diaphragm has a diameter greater than the diameter of the piston 91. The diaphragm can therefore no longer move, except for the displacement necessary for its operation, when it is housed in the body 94 of the safety valve 90.
- the fuel vapors circulating in the device 10 are charged with particles.
- the device 10 comprises a circular filter 100.
- the filter 100 is disposed on the path of the fuel vapors upstream of the plunger core 70. More specifically, the filter 100 is disposed at the opening 21 of the inlet duct 20 and before the plunger core and the orifice 23 of the valve seat.
- Such a circular filter makes it possible to block the particles directly at the outlet of the fuel vapor inlet conduit 20 and allows circulation of the fuel vapors without particles all around the electromagnetic system 60.
- the filter is an anti-particle filter making it possible to filter particles whose size is greater than or equal to 50 ⁇ m.
