Definitions

  • the invention relates to a container for the coolant of an internal combustion engine according to the features of the preamble of independent claim 1.
  • Such a container is known for example from WO-A-99 106 36.
  • the invention has for its object to provide a container for the coolant of an internal combustion engine, which is economical to produce and operates reliably under different operating conditions. This object is achieved on the basis of the preamble of independent claim 1 by its characterizing features.
  • the main advantage of the invention is the fact that in the container, a third chamber is arranged without much effort, which replaces the hose connection and works reliably.
  • the container for the coolant has a pressure relief valve.
  • the third chamber communicates with the first chamber by means of the pressure relief valve.
  • the pressure relief valve limits the outflow of liquid from the first chamber below a certain set pressure value.
  • This pressure relief valve is arranged according to an embodiment of the invention in the closure cap of the coolant reservoir or of the container.
  • the third chamber is provided with a tubular cross-section and is located on the wall between the first and the second chamber.
  • the structure and the manufacturing method for this third chamber is simple and economical, it is sufficient to provide the partition between the first and second chamber with an additional tube profile.
  • the container is made of thermoplastic material and will be made of two parts, namely a lower and an upper half of the container. Both container halves are welded or glued together. Since the second chamber has an outlet for the outflow of excess coolant, this chamber is designed pressure-free. Likewise the third chamber.
  • the container 10 consists essentially of a lower container half 12 and an upper container half 13. Both container halves are in the central region with flange connections 14 provided by ultrasonic welding, these two container halves are liquid-tightly connected to each other in the flange connection.
  • the container 10 thus forms a first chamber 11, a second chamber 15 and a third chamber 16.
  • a screw 17 is provided with an opening 18 in the upper area.
  • a closure cap 19th On this opening 18 is a closure cap 19th
  • the cap is equipped with a pressure relief valve 20.
  • This pressure relief valve 20 consists of a valve plate 21 which is mounted longitudinally movable in the cap 19. It is further provided a compression spring 22 which exerts a force on the valve disk in the axial direction.
  • the valve disc closes a valve opening 23 in the cap 19.
  • a prevailing in the chamber 11 pressure above a certain predetermined value addition opens the pressure relief valve 20 and releases a connecting channel 24 between the first chamber 11 and the third chamber 16.
  • the third chamber 16 is connected at the lower area with the second chamber 15 via an opening 25.
  • the second chamber 15 is equipped at its geodesic upper end with an outlet 26.
  • FIG. 2 shows the arrangement of the third chamber 16 within the second chamber 15.
  • the third chamber is arranged only in the form of a tubular profile on the partition wall 27. It will be understood from the illustration that this third chamber serves to provide communication between the first and second chambers suitable for transporting liquid from the second chamber back into the first chamber as the pressure in the first chamber falls.
  • the pressure relief valve 20 is provided with a return flap, which makes it possible that the liquid can flow back into the first chamber via the connecting channel.
  • the container is preferably made of transparent plastic, so that the liquid level can be controlled without the cap must be removed.
  • the first chamber is connected via an opening, not shown here, with the radiator of the internal combustion engine and ensures that sufficient cooling fluid is present in the radiator.
