Definitions

  • the invention relates to a cylinder head for a compressor, in particular a reciprocating compressor for use in motor vehicles, which is suitable for compressing a compressible working medium, in particular air, for use in a compressed air supply device of a motor vehicle.
  • the reciprocating compressor substantially consists of a main body and/or crankshaft housing or cylinder housing, in which at least one reciprocating piston is arranged, and a cylinder head.
  • ambient air is suctioned into the reciprocating piston chamber via an inlet channel, the ambient air is compressed and subsequently passed on via a channel.
  • the compressed air is passed on into a further and/or downstream compressor stage and is compressed further therein. The compressed air is subsequently conducted into the compressed air tank via an air treatment unit.
  • the object of the invention is to improve the cylinder head construction such that the efficiency of the reciprocating compressor is increased.
  • a cylinder head embodiment which is constructed such that an undesired heat transfer between two fluid flows is minimized. Further advantageous features of the embodiment according to the invention are disclosed in the subclaims.
  • a cylinder head for a reciprocating compressor for compressing a compressible working medium comprising a cylinder cover and a valve carrier plate, is proposed, said cylinder head being constructed as follows and having the following features.
  • An intermediate element is arranged between the cylinder cover and the valve carrier plate, and a plurality a channel sections and/or chambers are arranged between the valve carrier plate and the intermediate element and between the cylinder cover and the intermediate element and/or are formed thereby, through which various media flows can be conducted.
  • one or more insulation chambers are provided in the cylinder head, which at least in regions thermally insulate the channel sections and/or chambers from one another.
  • an inlet chamber and an outlet chamber are provided, the insulation chamber being arranged therebetween.
  • further insulation chambers may also be arranged between the different temperature ranges.
  • the insulation chambers contain enclosed ambient air. During assembly, therefore, no additional working step needs to be factored in.
  • the insulation chambers may also be filled with an insulating material or contain a vacuum.
  • the intermediate element has connection openings which connect together the channel sections and/or chambers in the valve carrier plate and in the cylinder cover. Thus the airflow and/or the cooling medium flow may pass from one plane to another.
  • the intermediate element may also be a sealing element.
  • FIG. 1 shows the reciprocating compressor with the cylinder head (section B-B)
  • FIG. 2 shows a plan view of the cylinder head (section A-A)
  • FIG. 1 shows a two-stage reciprocating compressor 1 and/or compressor with a cylinder head 2 in section.
  • the section line may be seen in FIG. 2 .
  • the cylinder head 2 is composed of the valve carrier plate 5 , the cylinder head cover 7 and an intermediate element 6 arranged therebetween.
  • the insulation chambers 9 . 1 and 9 . 2 are arranged such that, in particular, the channel section 10 , through which the hot compressed air of the second compressor stage 18 is conducted to the outlet opening 20 , is insulated from the chambers 14 . 1 , 14 . 2 , 15 . 1 and 15 . 2 . This prevents undesired heating of the intake air, in particular the cool ambient air, and the precompressed air which is conducted from the first compressor stage 17 to the second compressor stage 18 .
  • the path of the insulation chambers may be seen in FIG. 2 , wherein it may be identified that a complete separation is not necessarily achieved between the hot and cold airflows by means of the insulation chambers. However, the direct heat transfer through the metal partition walls is at least significantly reduced by the partial insulation.
  • the insulation chambers 9 . 1 and 9 . 2 are sealed cavities which are formed substantially by recesses in the valve carrier plate 5 and in the cylinder cover 7 and are closed by the intermediate element 6 .
  • the insulation chambers 9 . 1 and 9 . 2 are filled with ambient air which has been enclosed during assembly.
  • the precompressed air from the first compressor stage 17 is cooled as far as possible before it is suctioned into the second compressor stage 18 via the inlet chamber 14 . 2 .
  • the airflow is conducted from the outlet chamber 15 . 1 of the first compressor stage 17 through a connecting channel 19 in the cylinder housing 3 .
  • the walls of the connecting channel 19 are in contact at one point with the cooling channel 8 . 2 and additionally have a large cooling surface relative to the ambient air.
  • FIG. 3 shows an alternative construction for a cylinder head 1 .
  • This cylinder head differs substantially by the arrangement of the channels and chambers.
  • the insulation chambers 9 . 3 are arranged between the connecting channel 19 and the compressed air channel 10 .
  • the insulation chamber 9 . 3 is incorporated in the valve carrier plate 5 and is closed by the sealing element 4 .
