Definitions

  • the invention relates to a compressor, in particular for a Automotive air spring system, having the features in the preamble of the claim 1.
  • the invention has for its object to provide a compressor, in particular for a motor vehicle air spring system, in particular for a closed air spring system is suitable and existing back pressures always starting from any position can with self-priming in all areas.
  • the drawing shows a schematic Cutting a part of a drive motor, compressor and air dryer existing compressed air unit.
  • the compressed air unit 10 shown in the drawing has a schematic only indicated high-power electric motor 11 and a compressor 12, which are assembled into a unit. Part of this unit is further an only schematically indicated air dryer 13, in another, not also shown embodiment can be omitted.
  • the air dryer 13 extends in a space-saving manner above the motor 11 and extends to this approximately parallel, the transverse distance between the two being small.
  • the air dryer 13 with its housing directly to the Housing 14 of the compressor 12 attached.
  • the compressed air unit 10 is in particular for a motor vehicle air spring system determined, and here preferably for a closed air spring system.
  • a closed air spring system requires that within the system a pressure increase is made possible. This can mean that the pressures in the system of e.g. 2 to 10 bar can be increased must be set to e.g. 8 to 18 bar or even 20 bar or more.
  • the compressor 12 has in the housing 14 a cylinder chamber 15 in which a Piston 16 is tight and reciprocated.
  • a Piston 16 is tight and reciprocated.
  • the piston 16 closes with its upper end side 17 in the drawing together with the local area of the housing 14 a compression space 18, in which compressed air is compressed.
  • the compressed air is in the suction phase of on the outside via a supply line 19 and an opening 20 in the housing 14th sucked.
  • the compression space 18 has at least one outlet opening 21 which is closed by means of an openable outlet member 22, wherein the at least one outlet opening 21 and its outlet member 22 to the air dryer 13 open. Shown is also a further outlet opening 23 with Outlet 24 and connected discharge line 25, a compressed air outlet without air dryer 13 form.
  • the respective outlet member 22 and 24 consists of a pressure relief valve, which controls the pressure in the compression space 18 and is set so that it opens only when a set pressure is reached.
  • the at least one piston 16 is driven by a connecting rod 26, the by means of a bearing 27 on an eccentric portion 28 at the end of the motor shaft 29 of the motor 11 is rotatably mounted.
  • a balancing mass 30 attached to counterbalance.
  • another balancing mass 31st also be appropriate for mass balance.
  • the piston 16 is connected to the Connecting rod 26 movable via a transversely extending piston pin 32nd connected.
  • the compression space 18 has at least one arranged in the piston 16 Inlet opening 33 which closed by an openable inlet member 34 is.
  • the inlet member 34 is indicated only schematically and consists e.g. out a conventional flutter valve with a movable plate as a valve member. It's on Piston 16 is mounted centrally and in the region of the piston end face 17, wherein the Inlet member 34 at a compression in the compression chamber 18 automatically closed while it is in the suction phase under this suction pressure opens automatically.
  • the at least one inlet opening 33 in the piston 16 is over at least one guided by the piston 16 channel 35 with sucked air can be fed.
  • annular space 36 is available the channel 35 in connection.
  • annular space 36 instead in the cylindrical housing 14th educated.
  • the piston 16 peripherally an annular groove 37.
  • the axial dimension of the annular space 36, in particular the annular groove 37, is selected as a function of the lifting height of the piston 16.
  • the radial Depth of the annular space 36, in particular the annular groove 37, is dependent on desired delivery volume selected.
  • the piston 16 has two in the axial direction of this distance mutually arranged, the annular space 36 sealing piston rings 38 and 39, e.g. plastic, on. Further, the piston 16 carries guide rings 40, 41, the preferably also may be made of plastic.
  • the channel 35 has a center in the piston 16 and extending to the inlet opening 33 leading central channel 42 and at least one connecting channel 43, the central channel 42 with the annular space 36, in particular the annular groove 37, connects.
  • the central channel 42 is formed as an axial bore, which is centered by the piston 16 and thereby only over a part of its axial dimension, extends and which is open only to the inlet opening 33, while the other, the Piston pin 32 facing the end of the piston 16 is closed.
  • the at least one connection channel 43 is e.g. as a transverse bore in the piston 16 educated. It is understood that also several radial transverse bores This type can be provided.
