Definitions

  • the cooling circuit of an internal combustion engine must necessarily include a degassing device because one cannot ensure an absolute seal between the interior of the cylinders and the water chambers. You can degas the engine itself.
  • the volume of liquid to be heated is then significantly increased as soon as the engine is started, as this involves heating the liquid contained in the expansion tank as soon as it is started; the temperature rise of this engine and of its cooling circuit is therefore delayed, which increases external pollution due to the prolonged use of cold enrichment systems and, consequently, also increases fuel consumption and, in the case of a vehicle engine, interferes with heating of the vehicle interior.
  • French Patent 2,317,489 describes a liquid cooling device for an internal combustion engine which provides degassing of the cooling circuit as soon as the engine is started while minimizing the volume of the coolant to be heated after this start-up. market.
  • This cooling device comprises a main cooling circuit comprising a radiator connected to the engine by a liquid inlet pipe and a return pipe, means for circulating the liquid between the engine and the radiator, and a thermostatic valve suitable for interrupt the circulation of the liquid when the temperature thereof is below a given value, a secondary cooling circuit mounted in parallel with the main circuit and comprising a low-volume degassing chamber connected to the engine by a liquid inlet pipe and a flow, and means for circulating the liquid between the engine and the degassing chamber, and an expansion tank connected to one of the cooling circuits.
  • the cooling device is characterized in that the expansion tank is connected to the main cooling circuit and in that one of the walls of the degassing chamber has an orifice connected to the expansion tank by through a valve arranged to open when gas is present in the chamber; when the valve opens, the gas from the degassing chamber thus escapes to the expansion tank.
  • the degassing chamber is arranged under the expansion vessel and the orifice allows direct communication between the upper part of the degassing chamber and the lower part of the expansion vessel.
  • an internal combustion engine 1 which comprises a main cooling circuit comprising a pump 2.
  • the degassing chamber 14 has a circular section and the conduits 17 and 18 are of small section, less than that of the conduits 3 and 5, and open tangentially.
  • the degassing chamber 14 is disposed under the expansion vessel 8 and adjoined to it by its upper part, the upper wall of the chamber constituting a part of the lower wall 19 of the vessel; it has a small section orifice 20 through which it can communicate directly with the expansion tank and which can be closed by a valve 21.
  • the apparent density of this valve is slightly less than or equal to the density of the coolant. It is connected at its upper part by an arm 22 to retaining arms 23 which limit its downward stroke by abutting against the partition 19.
  • the valve 6 When the cold engine starts, the valve 6 is closed, so that there is no circulation in the radiator 4.
  • the only liquid which passes through the expansion tank 8 is that which reaches it through the orifice 20
  • the pressure P in the expansion tank 8 is practically identical to the suction pressure.
  • the pressure P ′ in the chamber 14 is intermediate between the pressure in the engine before the valve 6, itself close to the discharge pressure of the pump 2, and the suction pressure of this pump.
  • the pressure P ′ in the chamber 14 is therefore greater than the pressure P in the expansion tank.
  • valve 21 is constituted by a spherical body, which can be retained by the arms 23 of which it is integral and the orifice 20 is formed in a flat part of the partition 19. But in the embodiment of Figure 3, the orifice 20 is formed in a spherical portion 19 a of the partition 19 and the seal 21 is retained by arms 24 integral with the partition.
  • a tranquilization grid 25 can optionally be provided under the valve.
  • the valve is constituted by a cylindrical mass 26 which carries at its upper part a finger 27 adapted to close the orifice 20 which is formed in a truncated part that or spherical 19 b of the partition 19.
  • the mass 26 is guided and retained by the arms 24 secured to the partition 19.
  • the tranquilization grid 25 attached to the arms 24 is also provided in this embodiment.
  • Figure 5 illustrates an embodiment similar to that of Figure 4.
  • the valve 30 is movable in a space limited by a frustoconical or spherical part 19 c of the wall 19, the arms 24 and the tranquilization grid 25 It consists of a body 31 extended by an upper part 32 and a lower part 33 of smaller dimensions.
  • the part 32 carries the finger 27 and it is guided by centering arms 34.
  • the lower part 33 is in the shape of a cross and it passes through an orifice 35 of the grid 25.
  • the lower face of the body 31 has a part 36 in the shape of a truncated cone to avoid accidental sticking to the grid 25.
