Definitions

  • the air intake passage, the intake valve, the compressed air outlet passage, the exhaust valve and / or the additional valve are arranged in a cylinder head of the apparatus.
  • shut-off valve located upstream of the air dryer located downstream of the connection line, in particular directly connected to the connection line, a conventional air dryer may be used, for example.
  • the compressed air conveying system 10 has a compressor 12.
  • the compressor (also called air compressor) 12 is used to compress hot air to compressed air.
  • the compressor 12 may be configured, for example, as a reciprocating compressor with a reciprocable piston 14.
  • the piston 14 can be driven, for example via a drive connection (not shown), for example comprising a crankshaft and / or a gearwheel drive, by an internal combustion engine of the motor vehicle, in particular coupled to its rotational speed.
  • the compressor 12 has a cylinder head 16 and a cylinder 18.
  • the cylinder head 16 covers the cylinder 18.
  • the piston 14 is guided.
  • an air inlet passage 20 and a compressed air outlet passage 22 are provided in the cylinder head 16.
  • the cylinder head 16, the cylinder 18 and the piston 14 define a compression space 24.
  • air is compressed to compressed air when the driven piston 14 is moved from a bottom dead center to a top dead center of a piston movement of the piston 14.
  • a cooling device and / or a cooling channel may be provided for cooling the compressor 12.
  • a volume of the switchable dead space 42 is limited on the one hand by the additional valve 38 and on the other hand by the shut-off valve 36.
  • the volume of the switchable dead space 42 can be set as desired.
  • the invention is not limited to the preferred embodiments described above. Rather, a variety of variants and modifications is possible, which also make use of the inventive idea and therefore fall within the scope.
  • the invention also claims protection of the subject matter and the features of the subclaims independently of the claims referred to.
  • the features of independent claim 1 are independently disclosed.
  • the features of the dependent claims are also disclosed independently of all the features of independent claim 1 and, for example, independently of the features relating to a presence and / or a configuration of the compression chamber, the compressed air outlet channel, the outlet valve and / or the auxiliary valve of independent claim 1.
