Definitions

  • the technical sector of the present invention is that of devices for adjusting and controlling a pressure prevailing in a capacity and it relates more particularly to the inflation and deflation of a tire of a wheel of a vehicle.
  • patent FR-A-1563179 describes a kind of valve suitable for inflating and deflating with the disadvantage that it is impossible to be simply regulated, a great complexity in its driving circuit and an irremovable assembly.
  • the patent FR-A-2598771 describes a pneumatic valve controlled remotely which is constituted by two inflation and deflation bodies delimiting two cavities, said respectively of intake and exhaust. These two cavities communicate with each other by an intercommunication which forms in the chambers two seats for two slave valves and which is in relation, between the seats, with a connecting channel leading to a connection well to a piloting installation.
  • the exhaust chamber is connected to the ambient environment by holes in the open air.
  • the inflation and deflation valve according to the invention has the undeniable advantages of being implemented very easily and of having the possibility of being installed permanently or in a removable manner.
  • the subject of the invention is therefore an inflation or deflation valve at at least a predefined pressure intended to regulate and / or control the pressure of a fluid within a capacity, comprising a membrane interposed between a first body and a second body connected together by a connecting means, said membrane delimiting a first chamber with the first body and a second chamber with the second body being supported by the action of a spring on a seat delimited by the lower body, characterized in that the lower body comprises a supply pipe connecting the second chamber to the capacity by means of a valve, said pipe emerging from the side of the second chamber through the seat, at least one calibrated exhaust pipe being formed in the lower body to make the second chamber communicate with the external environment for constitute a pneumatic means for adjusting said predefined pressure.
  • the spring is calibrated to exert a determined force on the membrane as a function of the predefined pressure.
  • the pneumatic adjustment means is constituted by the pressure prevailing in the second chamber.
  • the second body comprises at least two calibrated exhaust pipes and a selection means for putting one of said pipes in communication with the outside environment.
  • each of the preset pressures is conditioned by a particular restriction.
  • the preselected pressure selection means comprises a rotary shutter provided with a first lumen for communicating an exhaust pipe with the external medium, the other exhaust pipes closed by the shutter.
  • the selection means is provided with a second light to make an indication appear on the value of the preset pressure.
  • the rotary shutter has a lever for ensuring its rotation manually.
  • the deflation is caused by the distance of the membrane from the seat.
  • the separation of the membrane is ensured by pressurizing the second chamber using an external pneumatic source.
  • the separation of the membrane is ensured by compression of the spring produced using a slide, one end of which is accessible.
  • the pipe is linked to the capacity valve in a removable manner.
  • a very first advantage of the inflation and deflation valve according to the invention lies in its ease of implementation.
  • Another advantage of the invention lies in its ability to be removable, thus constituting an accessory of the vehicle.
  • valve is adjustable according to the pressure necessary for the course envisaged.
  • valve according to the invention lies in the fact that all of the pneumatic sources can be used and thus overcome the conventional inflation devices.
  • FIG. 1 is a sectional view of the valve according to the invention according to a first embodiment
  • FIG. 2 is a sectional view of the valve according to the invention according to a second embodiment
  • FIG. 3 is a bottom view of the valve according to the invention shown in Figure 1.
  • the inflation and deflation valve 1, illustrated in FIG. 1, is constituted by a first body 2 and a second body 3 between which a membrane 4 is interposed.
  • the two bodies 2 and 3 are machined to delimit with the membrane 4 respectively a first chamber 5 and a second chamber 6.
  • These two bodies 2 and 3, made of any material appropriate, are connected together face to face on their peripheries thus sealingly sandwiching the periphery of the membrane 4.
  • This assembly is provided by a connecting means according to two discontinuous vertical lines A and B which may be for example screws, rivets or any interlocking.
  • the second body 3 has, inside the second chamber, a seat 7 on which the membrane 4 rests.
  • a pipe 8 is produced in the body 3, one of these ends opening into the second chamber 6 in passing through the seat 7 and the other end is connected to a valve 9 of known type generally mounted on the rims of the wheels of a vehicle
  • valve 1 (not shown).
  • the connection between the valve 1 and the valve 9 can be done by a threaded, clipped system or any other sealed connection system. Obviously this connection can be of the fixed type for permanent mounting of the valve 1 or of the removable type for episodic adjustments and / or controls. In the latter case, the valve 1 constitutes an accessory of the vehicle and can be stored in the glove box for example.
  • the valve 9 is connected to a capacity 10 which is in the example described for example a tire.
  • the body 3 has at least one calibrated pipe 11 which can advantageously be dimensioned by its diameter or its length or both to ensure pressurization of the chamber 6 as will be explained below.
  • This pipe 11 puts the interior of the second chamber 6 into communication with the external environment.
  • a spring 12 is disposed in the first chamber 5, one of its ends being in contact with the bottom of the body 3 while the other is in abutment on the membrane 4 by means of a washer 13.
  • the invention is limit to this embodiment if the valve is intended to offer a single preset pressure.
  • the second body 2 has as many restrictions as presetting pressures imposed by the vehicle manufacturer for proper use of the tire.
  • the second body 3 comprises two pipes 14 and 15, one of which is invisible by the section of the valve 1 shown.
  • a coisseau 16 which is threaded in the twisted spring 12.
  • This coisseau 16 is integral at one of its ends with the washer 13 while at the other end which protrudes from the body 2, it is shaped to facilitate its manipulation by a user, for example thanks to a knurled end.
  • This cwellisseau 16 can, depending on the case, be installed on the side of the body 3 by crossing the pipe 8 to come to bear on the membrane 4.
  • a selection means 17 comprises a rotary shutter 18 connected to the lower body 2 by an axis of rotation 19 in a substantially sealed manner.
  • This rotary shutter 18 has two openings 20 and 21, the production of which will be more detailed in the description according to FIG. 3.
  • the shutter 18 is made to rotate thanks to a lever 22 actuated manually by the user and visible in FIG. 3.
  • FIG. 3 shows, in a view from below, the general shape of the valve 1.
  • a selection means 23 made up of the rotary shutter 18 and the lever 22.
  • the role of the rotary shutter 18. As described above, it has two lights 20 and 21. One of them reveals a mention relating to the terrain that the user is traversing or planning to traverse. The other light releases a channel, 14 for example, in connection with the mention revealed by the first light.
  • the mentions are written by any means on the face of the body 3. It is noted in the example illustrated in this figure that only the mention "route” appears while the other mentions "Highway” and “sand” are hidden, the pipes 24 and 25 corresponding to these invisible indications being hidden by the rotary shutter 18. Of course, these indications are given by way of illustration and may vary depending on the vehicle concerned. We also note the difference in diameter of the pipes. More this pipe is small, the pressure in 'the membrane and the greater the time of deflation will be long.
  • the valve 1 comprises, in an inventive manner, a pneumatic adjustment means in order 'to reach a preset pressure.
  • This adjustment means is mainly constituted by a means for fixing the preset pressure, the means 17 for selecting this pressure and a means for signaling the pressure reached, the latter being constituted by the flow of pressurized air according to the arrow.
  • the production of the means for fixing the preset pressure is based on a pneumatic principle.
  • the pressure of the fluid contained in the chamber 6 (coming from the tire 10) exerts a so-called adjusting force on the membrane 4. This adjusting force is counteracted by the force exerted by the spring 12 on the membrane 4.
  • the adjusting force is conditioned by the characteristics of the exhaust pipe 14, 24 or 25 updated by the rotary shutter 18.
  • valve 1 The operation and use of the valve 1 according to the invention is as follows. At rest when it is fixed to the valve 9, the valve 1 prohibits any outflow of fluid from the tank 10 because the spring 12 exerts a force on the membrane 4 thus preventing the circulation of fluid between the pipe 8 and the chamber 6.
  • the valve 1 lets the fluid pass to the capacity 10.
  • a pneumatic source for example a portable blow gun
  • the connection of a pneumatic source takes off the membrane 4 from the seat 7 and allows entry of the fluid in the capacity 10 via the line 8 and the valve 9. This operation is carried out for any time.
  • the application of the pneumatic source is not necessarily waterproof.
  • the preset pressure is certainly reached and, by this process, the user is informed. Valve 1 then automatically adjusted the pressure. - If the pressure injected into the capacity 10 is not sufficient, the value of the pressure corresponding to that preset by the selection means 17 has not been reached. The membrane 4 will immediately close off the seat 7. In this case, the user has not detected the signaling means by the evacuation of fluid and understands that the inflation as many times as necessary to detect the ejection of fluid under pressure according to arrow F.
  • the preset pressure can be reached in two different ways.
  • the first way does not require a rod 16. It consists in applying the rudimentary pneumatic source to the pipeline for a very short time. The membrane 4 will then be raised and, as described above, it will not close the seat 7 until the capacity 10 has reached the preset pressure.
  • the second way of ensuring deflation consists in releasing the membrane 4 from the force exerted by the spring 18 for a very short time. This can be done by compressing the spring 12 by pulling the coil 16 connected to the washer 13. The pressure prevailing in the capacity 10 then lifts the diaphragm 4 from the seat 7 and, as described above, this will only close the seat when the preset pressure is reached.
  • This coisseau can also be installed opposite (not shown) the membrane 4 which it will push then thus allowing the fluid to circulate from the capacity 10 towards the chamber 6. Different possibilities can allow the arrival of the fluid in the chamber 6 without, however, changing the spirit of the invention.
  • a user of an all-terrain vehicle equipped with a valve according to the invention with four preset pressures mounted integral with each wheel, travels from road terrain to sandy terrain. He ignores the pressure prescribed for this type of terrain.
  • the valves 1 are not equipped with a valve 16 for deflation. However, it does have a small supply of cheap pressurized gas such as a manual bomb.
  • the user positions the selection means 17 on “sand” and applies the reserve of gas under pressure at the only accessible pipe, for about one second.
  • the signaling means according to arrow F the user can move to the following wheels. For a six-wheeled vehicle, for example, the user will only get out of the vehicle for around thirty seconds. The deflation times are considerably reduced and the required pressures are adjusted automatically.
