Definitions

  • a transparent window is arranged in the wall of the chamber integral with the water box or is cast in during manufacture. Since the main part of the chamber is largely opaque, the coolant level hardly rises against the dark interior of the chamber and can therefore not be reliably determined from a normal viewing distance.
  • the object of the invention is to design the partially transparent chamber so that the coolant level is always clearly visible from the usual observation distance.
  • the invention provides the characterizing features of claim 1.
  • the control of the coolant level corresponds to that in the case of a fully transparent chamber arranged separately from the water tank, without having the additional space requirement and construction expense for its multi-part design, connecting lines and fastening elements.
  • the invention makes it possible, on the one hand, to form the water tank with the lower part of the chamber from high-strength, fiber-reinforced and therefore opaque plastic and, on the other hand, to design the transparent upper part with a pressure-resistant, approximately circular cross section.
  • a cross-flow cooler 1 for an internal combustion engine (not shown) has a water tank 2, into which a flow line 3 of the cooling circuit of the internal combustion engine opens.
  • a storage, ventilation and compensation chamber 4 is attached to the water tank 2.
  • the lower part is molded in one piece with the water box 2 from unbreakable fiber-reinforced plastic.
  • the lower part 5 of the chamber 4 which is in one piece with the water tank 2, is also a hose connector 11 for a filling and secondary flow return line 12, the mouth 6 ', a branch 13 from the ventilation line 6 to a control line 13', one in a horizontal dividing plane 14 lying surface for an upper part 15 of the chamber 4 formed.
  • the upper part 15 of the chamber 4 consists of a transparent plastic of lower strength. The lower strength is compensated for by an approximately circular cross-sectional shape of the upper part 15, so that the overpressure values that occur during operation of the internal combustion engine can be safely accommodated in the chamber 4.
  • the parting plane 14 between the lower part 5 and the upper part 15 lies below the normal range of the coolant level 16, so that the coolant level 16 can be determined in the transparent upper part 15 in a clearly visible manner even with a larger observation distance.
  • a filler neck 17 is integrally formed on the upper part 15, to which the parts of the control line 13 ′ and an overflow line 18, which are also integral with the upper part 15, are connected.
  • the filler neck 17 is closed with a filler cap 19, which contains valves for the pressure control of the cooling circuit in a known manner.
  • the sections of the vent line 6 and the control line 13 ' are molded onto the outside of the two plastic molded parts with the interposition of ribs 20.
  • the control line 13 ' connects in the parting line 14 to the branch 13 from the vent line 6, so that separate connecting elements are unnecessary.
  • the vent line 6 and the control line 13 ' can be arranged one behind the other in the practical training in the viewing direction of the drawing, whereby a space-saving, closely fitting arrangement of the water tank 2 and the chamber 4 can be achieved.
