Definitions

  • the present invention relates to a heat engine for a motor vehicle equipped with an air conditioning device which comprises a compressor fixed to the block of said engine, said compressor comprising a metal housing enclosing a compression member driven in rotation by the engine to compress a refrigerant.
  • the metal housing of the compressor of the air conditioning device is fixed laterally to the engine block using a support which is screwed to this block, the housing itself being screwed to the above support.
  • the internal compression member of the compressor is driven by a pulley connected by means of a belt to a pulley generally fixed to the end of the engine crankshaft.
  • These pulleys and belts also clutter the space available around the engine. Furthermore, this belt must be tightened and replaced periodically, which is also tedious and expensive.
  • the object of the present invention is to remedy the above drawbacks.
  • the invention thus relates to a heat engine for a motor vehicle, equipped with an air conditioning device which comprises a compressor fixed to the block of said engine, said compressor comprising a metal housing enclosing a compression member driven in rotation by the engine to compress a fluid. refrigerant.
  • this heat engine is characterized in that the metal housing of the compressor is made in one piece with the engine block by molding thereof, so that part of the wall of said housing is common with the wall of the engine block.
  • the integration of the compressor housing in the engine block reduces the size of the compressor inside the engine compartment and therefore facilitates access around the engine.
  • FIG. 1 shows a heat engine comprising an engine block 1, produced by casting in cast iron or aluminum, the upper part of which receives a cylinder head 2 and the lower part, a casing 3.
  • This heat engine is equipped with an air conditioning device which comprises a compressor 4 fixed to block 1 of said engine.
  • This compressor 4 includes a metal housing 5 containing a compression member which is rotated by the motor to compress a refrigerant.
  • the metal housing (the metal housing 5 of the compressor) is made in one piece with the engine block 1 by molding the latter.
  • part of the wall 6 of the housing 5 is common with the wall of the engine block 1.
  • the compression member 7, housed inside the housing 5 is rotated by mechanical members 8, 9, located inside the engine.
  • these mechanical members comprise a toothed wheel 8, which can also be a toothed wheel, integral with one end of the drive shaft 10 of the compression member 7.
  • This wheel toothed 8 is driven by a chain 9 which can also be a toothed belt located inside the engine.
  • This chain 9 or toothed belt can be connected or be part of the engine distribution members.
  • the housing 5 of the compressor integrated into the motor 1 comprises at one of its ends a face 11 from which the shaft 10 of the compression member 7 which projects the toothed wheel 8 or notched protrudes. This face 11 receives a closing cover 12.
  • the face 11 of the housing 5 is located in the assembly plane 13 to the engine block 1 of the cover 12 in which are housed the chain or the toothed timing belt of the engine.
  • the reference 14 designates an electromagnetic clutch making it possible to decouple and couple the pulley 8 relative to the shaft 10.
  • the compression member 7 of the compressor can be lubricated by the engine lubricating oil.
  • the compressor housing can have for this purpose on its wall adjacent to the engine block 1 passages (not shown in the figures) communicating with the engine lubrication circuit.
  • the compressor instead of being arranged in the direction of the length of the engine, could also be arranged in the direction of the height of the engine block, as in the case of igniters of petrol engines.
