Definitions
- the present invention relates to a device for ventilation of an engine compartment of a vehicle, engine of this vehicle being fitted with filtration dynamic intake air and fan dust extraction.
- the engine compartment of a vehicle constitutes a hot source of radiation that can help detect it and characterize.
- the concern for discretion in a situation conflict requires the reduction of such radiation, and we have already proposed to integrate a specific fan in the engine compartment for stir the air.
- This solution generates a certain number disadvantages that cannot be overcome.
- the volume dedicated to this fan additional is done at the expense of other equipment.
- the energy useful for the functioning of this fan will burden the vehicle's electrical balance, and it is essential to provide a diet electrically protected and electronically controlled.
- the cost of a fan compatible with the requirements military is high.
- US-A-3951114 describes a system for cooling of this type.
- the motor is enclosed in a compartment and a fan blows the air drawn in through an inlet duct at the level of the compartment. After stopping the engine, further ventilation while maintaining the functioning of the fan.
- This system therefore operates by vacuum.
- the object of the invention is to alleviate such disadvantages in proposing a ventilation device not using an independent fan.
- the invention provides a device for ventilation of an engine compartment of a vehicle after stopping its engine, equipped with a fan dust extraction system and a cyclonic filter of engine intake air, bypassed with the ventilator, characterized in that it consists of a means of communication interposed between the fan and the engine compartment, the operation of which is controlled by the vacuum prevailing in the circuit engine intake.
- the communication means is connected to the engine manifold through a conduit.
- the actuator is slidably attached to a fan suction nozzle.
- the actuator is in the form of a envelope with bottom, in which is engaged the end of the nozzle.
- the envelope is likely to occupy a first so-called closed position where it covers openings formed in the wall of the nozzle and a so-called position open where it releases these openings.
- the valve is in the form of a bellows elastic connected to the vacuum-controlled duct for ensure its folded position.
- the bellows is integral on either side of the bottom and nozzle.
- the bottom is provided with a vent for the passage of the air.
- the bellows is in the form of a closed flexible envelope surrounding a helical spring.
- the duct is connected to the bellows by through a screw connection at the bottom.
- a fan is simply controlled existing, without the need to intervene to ventilate the engine compartment.
- the passage of the actuator from its closed position to its open position is done automatically without any intervention, from the depression of the duct.
- FIGs 1 and 2 there is shown a compartment 1 in which is housed a suction motor 2 air through a cyclone box 3 according to the arrow F1.
- This box 3 is provided with a filter 4 constituting a fine dust barrier.
- This box 3 is also connected by a duct 5 with a fan 6 preceded by a nozzle 7 to evacuate large dust to outside according to arrow F4.
- Motor 2 is equipped, conventionally, an air intake manifold 8 placed downstream of the filter 4 and in which there is a vacuum depression, and manifold exhaust gas discharge 9 to the outside along arrow F2.
- a means for communication consisting of a conduit 10 and a pneumatic actuator 11.
- This duct is connected on one side to the intake manifold 8 and on the other side to the actuator 11.
- the latter is integral with the nozzle 7 and contains a valve 12.
- the assembly duct 10-actuator 11-valve 12 does not disturb its operation.
- the filtered air arriving at the cyclone 3 is directed for the most part via the nozzle 7 towards the collector 8, while a small part of this filtered air is directed to fan 6.
- the vacuum prevailing in the manifold 8 control the pneumatic actuator 11 via the line 10, and holds the valve 12 in position closed. Simultaneously fan 6 sucks in through duct 5 the air loaded with large dust which is discharged to the outside.
- FIG 3 there is shown in section a embodiment of the actuator 11 integrated into the nozzle 7.
- This nozzle 7 supports on one side the fan 6 and on the other the pneumatic actuator 11. In its part intermediate between the fan 6 and the actuator 11, the nozzle 7 receives the conduit 5 connected to the cyclone 3.
- the actuator 11 consists in this example of realization of a cylindrical envelope 15 in which an equally cylindrical part of the nozzle is engaged 7, and a bottom 16.
- the casing 15 is slidably mounted relative to nozzle 7 to occupy two positions per compared to this: a closed fallback position represented on the half-section from the top of the figure and a deployed open position shown in the half-section from the bottom of the figure.
- the nozzle 7 is provided with openings 13 which are obstructed in the fallback position of the envelope 15 and released in the deployed position. It is the bottom 16 which carries a vent 17 and receives the conduit 10 provided with a nozzle 18 via a fitting 19.
- the valve 12 here consists of a elastic metal bellows 20 constituting a sealed sealed envelope with a spring helical, subjected to depression and it is fixed on either side at the bottom 16 and at the nozzle 7.
- the vent 17 facilitates the passage of the bellows 20 from the folded position to the deployed position and vice versa.
- this is the implementation depression of the conduit 10 which passes the bellows 20 from the deployed position (lower half-cut) to the folded position (upper half-cut), after placing engine running.
- the aspiration by the conduit 10 causes the bellows 20 to fold back and causes the sliding of the casing 15 relative to the nozzle 7 according to arrow R and therefore the closing of the openings 13.
- the absence suction in the conduit 10 causes deployment along the arrow D of the bellows 20 and therefore the clearance openings 13.
- the air in engine compartment 1 is then sucked in by fan 6 through openings 13.
