Definitions

  • the present invention relates to a device and a degassing process for motor vehicles. It applies in particular, but not exclusively, to a degassing device for the coolant of a heat engine, particularly for motor vehicle engines.
  • the degassing box is an essential element of the engine block first of all concerning the management of the gases circulating in the liquid but also at the level of the aforementioned technical functions that it must provide first.
  • French Patent No. FR 2579668 relating to a degassing box composed of two communicating compartments, an upper part and a lower part.
  • the upper part allows the degassing of the liquid by phase shift of the upper jet by breaking it on a partition, called due tranquilization. This process is not effective because it generates turbulence.
  • the lower part allows centrifugal degassing of the lower jet by creating a vortex, however this vortex is directly connected with the liquid outlet, so degassing can not be done properly.
  • the patent N ° FR 2730272 also describes a degassing box composed of two communicating compartments.
  • the first compartment allows centrifugal degassing of the upper jet in a cylinder.
  • the openings in the lower part of the cylinder do not contain all the turbulence thus disrupting the effectiveness of degassing.
  • the second compartment allows to create a calm zone to complete the degassing of the liquid. This design does not provide for inferior arrival.
  • a degassing device for the coolant of a heat engine especially for motor vehicle engines, comprising at least one lower compartment in which is fed via a supply conduit , a part of the coolant, and at least one upper compartment into which is fed, via another feed conduit, another portion of said liquid, the compartments each having a different diameter, characterized in that the two compartments are in cylindrical form and in that the compartment with the smallest diameter, called inner diameter, is protruding inside the larger diameter compartment, called outer diameter.
  • the aforesaid inner diameter will be chosen as a function of the flow rate of the liquid to be degassed.
  • the supply ducts of the two aforesaid compartments will be respectively oriented perpendicularly to the two compartments, lower and upper.
  • the lower compartment is supported on the outer casing via a base, constituted for example by a plurality of feet.
  • the degassing device will comprise an outer casing in which the two aforesaid compartments are housed.
  • the casing of the degassing device will be in spherical form; this envelope may be composed of at least two parts, for example identical.
  • the two parts forming the outer envelope may be heat sealed, for example at the sidewalk or part of their edges.
  • the casing will have a diameter corresponding to a desired volume, for example at least equal to the total volume of liquid to be degassed.
  • the outer casing as well as the two aforesaid compartments are molded thermoplastics, obtained for example by injection.
  • the envelope and the two compartments may be made of propylene.
  • the degassing device will include an outlet duct for the coolant so that the latter, once degassed, can be evacuated by the effect of its own weight, that is to say by gravitation.
  • the two compartments will extend vertically, substantially along a central axis of the outer casing.
  • the two compartments will extend vertically, substantially close to one of the edges of the outer casing.
  • the tangential displacement of the cooling liquid in each of the compartments takes place in the opposite direction.
  • the invention thus makes it possible to improve the degassing in the liquid, or the fluid, of cooling in all the operating phases of a motor vehicle engine.
  • the device according to the invention by its compactness, easily integrates into the constraints of size of the motor behavior and achieves, by its particularly simple design, very competitive manufacturing costs.
  • the device of the invention makes it possible to integrate several liquid inlets "in air” and / or "underwater”.
  • the figure 1 describes a conventional cooling circuit.
  • the cooling circuit in motor vehicles is composed mainly of a heat engine 1 to be cooled, a pump 2 for the circulation of the liquid, radiators 3, 3 'ensuring the heat exchange and a box, or device, degassing device 4.
  • the liquid to be degassed coming from the radiator 3 ', enters the degassing device 4 via a supply duct 5.
  • This supply duct 5 of the coolant is oriented tangentially to a first upper cylindrical compartment 6, thus allowing the liquid to flow along the wall of the compartment 6.
  • This cylindrical compartment 6 is protruding in a second compartment lower 7, also cylindrical but of greater diameter than that of the first compartment 6.
  • the first compartment 6 opens at the bottom in a second compartment 7 so that, thanks to the nesting of the two compartments 6 and 7 one in the other, the turbulence of the coolant remain trapped.
  • the respective diameters of the two cylindrical compartments 6 and 7 depend on the flow rate of the liquid to be degassed.
  • the liquid to be degassed coming from the cylinder head, enters the degassing device via another supply duct 8 which is also oriented tangentially or perpendicularly to the wall of the second cylindrical compartment 7.
  • the second compartment 7 is equipped in the lower part of a base 9, ideally constituted by a plurality of feet positioning in height so that it is always immersed with respect to the level of the liquid.
  • the lower compartment 7, having a diameter greater than the upper compartment 6, allows the liquid to flow into an outer casing 10 housing the two said lower compartments 7 and upper 6.
  • the liquid being tranquilized, degassing can operate by gravity and leave the degassing device through an outlet orifice 11 located at the bottom of the degassing device.
  • the degassing device is composed of an upper half-shell 12, a lower cylindrical compartment 13 and a lower half-casing 14.
