Definitions

  • the invention relates to a cooling device for a flame ring or for the head of a liner of a reciprocating diesel internal combustion engine, the cooling water ring surrounding the flame ring or the head of the liner and arranged directly in the flame ring or in the head of the liner and separated from one another Has channels with water outlet and water inlet openings.
  • the object of the invention is to provide a cooling device which is simple in the head of the liner or can be produced in the flame ring and ensures a continuous flow or exchange of cooling water from one annular chamber to the other annular chamber in order to achieve optimal cooling of the liner and / or the flame ring.
  • the channels each have a tangential course to the inner bore of the flame ring or the head of the liner, and that between the cooling water ring and the flame ring or the head of the liner a narrow, superimposed cooling water ring channels interconnecting annular gap is provided and that the channels are each arranged in different inclined planes, the water inlet openings in the lower cooling water ring channel and the water outlet openings in the upper cooling water -Ring channel open.
  • the main advantages achieved by the invention are that with an arrangement of the cooling device, which consists of several water-carrying through channels, which are arranged tangent to the inner bore of the liner or the flame ring, a continuous flow of cooling water is ensured.
  • the arrangement of the channels is selected so that the entire ring area is penetrated by channels and thus the hottest areas of the liner or the flame ring or the inner bore can be cooled uniformly.
  • the channels are preferably placed in inclined planes in such a way that a cooling water connection from a lower cooling water annulus to a further cooling water annulus arranged above them can take place through straight-line channels produced as bores.
  • a narrow gap connecting the two superimposed cooling water annular spaces is provided between the flame ring or the bushing and a surrounding cooling water bushing.
  • the sloping channels in the liner or in the flame ring are arranged separately from each other, so that separate cooling water flows can be transported from one annulus to the other annulus and thus optimal cooling is achieved.
  • a flame ring 3 is arranged in a diesel engine between the cylinder head 1 and a liner 2, which is enclosed by a cooling water ring 4.
  • This surrounds a cooling water space, consisting of a lower cooling water ring space 5 and a further cooling water ring space 6 arranged above it.
  • These two spaces 5 and 6 are interconnected via an annular gap 7, which is either between the flame ring 3 and the cooling water ring 4 or at a version without flame ring 3 between the head 2a of the liner 2 and the ring 4.
  • the cooling device can be provided in the head 2a of the liner 2 or when arranged with a flame ring 3 therein.
  • Connection channel 8 may be provided. This has a lower inlet opening 9 and an upper outlet opening 10. As a result, cooling water from the lower annular space 5 to the upper annular space 6 flows optimally through the edge zone of the flame ring 2 or the head 2a of the liner 2a.
  • a plurality of channels 11 to 18 are arranged in the flame ring 3 or in the head 2a of the liner 2. These channels are each tangential and close to the inner bore. They surround the inner bore 20 or 21 in such a way that - viewed in plan view - four channels 11 to 14 each form a square formation and a further four channels 11 to 14 are arranged offset, an optimal arrangement of the offset at an angle of approximately 45 °. However, an offset at a different angle is also conceivable.
  • the channels 11 to 18 are all set apart and obliquely and each have an inlet opening 9 to the annular space 5 and an outlet opening 10 in the upper annular space 6.
