Definitions

  • the invention relates to a spray nozzle for cooling a piston of an internal combustion engine according to the features of the preamble of patent claim 1.
  • So-called piston spray nozzles for cooling the high-temperature-loaded pistons are in particular used in high-performance engines.
  • the inclusion or attachment of these spray nozzles in the engine or crankcase of the engine takes place in various ways.
  • the spray nozzle is screwed into the crankcase;
  • the spray nozzle on a fastening tab which is fixed with a screw on the crankcase. Since the spray nozzle are mounted in the region of the bearing blocks of the crankcase, such attachment leads to an unwanted weakening of the bearing block.
  • the object of the invention is to attach the spray nozzle to the crankcase so that a simple installation and tension-free recording of the spray nozzle in the bore is possible, and a weakening of the crankcase in the bearing block area is prevented.
  • the fuse element provided on the spray nozzle which engages with a section in a bore provided in the crankcase, ensures in a simple manner that the spray nozzle can no longer rotate after being received in the bore provided in the crankcase.
  • An interference fit between the sleeve of the spray nozzle and the bore is thus no longer necessary; a transition fit is sufficient to seal the sleeve of the spray nozzle relative to the bore wall.
  • a disk or oval sheet formed securing element is disposed between the sleeve body and the actual nozzle and thus serves at the same time as an axial stop surface for the inserted into the bore sleeve body of the spray nozzle.
  • annular groove is provided at the end of the sleeve body received in the bore, in which a spring ring is received for locking the sleeve body in the bore;
  • the bore In the area of the spring ring, the bore has a step, so that the shoulder that forms thereby acts as a stop for the spring ring.
  • the supply of spray oil takes place in an advantageous manner via the oil supply groove provided for the main bearings of the crankshaft.
  • the sleeve body receiving bore communicates with the main bearing ⁇ lumpssnut.
  • the single FIGURE shows a nozzle attached to the crankcase of an internal combustion engine for cooling a piston.
  • crankcase 2 of an internal combustion engine is partially shown in the bearing block area of the crankshaft.
  • a sleeve body 6 of a spray nozzle 8 is received for cooling a piston of an internal combustion engine.
  • the spray nozzle 8 has a hook-shaped nozzle line 10, via the free end of which the piston head is acted upon by spray oil for cooling.
  • a securing element 12 is provided, whose base body 12a is disc-shaped or oval-shaped and has an extension 12b, which engages in a provided in the crankcase 2 blind hole 14.
  • the extension 12b is, for example, as angled locking nose, locking pin, security pin o.ä. educated.
  • a design is also conceivable in which the securing part engaging in the bore 14 is punched out of the locking plate itself as a securing section. This ensures that the spray nozzle can no longer rotate after its installation.
  • the recorded in the bore 4 end of the sleeve body 6 has an annular groove 16 in which a spring ring 18 is receiving.
  • the spring ring 18 is used for axial securing of the spray nozzle 8 in the crankcase 2.
  • the step 20 serves as a stop surface for the spring ring 18 and thus ensures that the spray nozzle 8 is locked captive in the bore 4.
  • the outer diameter of the sleeve body 6 and the diameter of the bore 4 are formed, for example, as a transition fit, so that a sufficient seal is ensured. Additionally or alternatively to the transition fit, it is also conceivable that a sealing of the sleeve body 6 in the bore 4 by a 0-ring, which is selectively inserted either in the bore 4 or in an annular groove in the sleeve body 6. The position of this 0-ring would be at the beginning of the bore 4, directly in the area under the fuse element 12, provide.
