Definitions

  • the invention relates to a reciprocating compressor with a crankcase, which is provided with a venting device, wherein the venting device comprises an oil filter, which is connected on the inlet side with the crankcase and the outlet side with the atmosphere.
  • a secondary compressor is used to increase the pressure of air or other environmentally friendly gases.
  • the document DE-A-195 25 461 describes a conventional, from the atmosphere sucking compressor with an oil filter which is arranged in a separate, connected via lines to the crankcase housing, the input side to the crankcase and the output side connected to the suction line of the compressor and On the input side forms an oil collection chamber whose oil outlet is in communication with the crankcase.
  • Document DE-A-197 29 439 describes an engine with an oil filter which is connected on the input side to the crankcase and on the output side to the intake passage of a turbocharger and has an oil collecting space whose oil outlet communicates with the crankcase via a non-return valve arranged in a horizontal return line stands.
  • the invention is therefore based on the object to avoid the unwanted oil leakage in the venting of the crankcase, but at least to reduce drastically.
  • the invention is based on the finding that only very little space is available to the wire mesh filter in the low-turbulence, that is to say the upper region of the crankcase.
  • the consequent small passage area leaves only one low pressure loss, if the vent should work effectively and reliably.
  • the low permissible pressure loss in turn leads to a correspondingly large-meshed wire mesh filter. This explains the high permeability for smaller and even larger oil droplets.
  • the very fine filter used according to the invention which as a rule consists of a microfiber web, can reliably retain the oil components of the mist.
  • the residual oil content can be reduced to less than 0.01 mg / m 3 .
  • the micro-filter needs a correspondingly larger area, which is provided by the oil collection room.
  • the wall of the oil collecting chamber forms an effective shield against direct oil application of the ultrafine filter.
  • the surface of the ultrafine filter can thus also extend into areas of the crankcase, which can not be described as turbulence poor.
  • the dripping oil from the ultrafine filter can be discharged continuously or intermittently from the oil collection chamber via the oil outlet in the crankcase. If a permanently open passage is provided, this is kept so small that a direct application of oil to the ultrafine filter is omitted.
  • the superfine filter in a separate, connected via lines to the crankcase housing, wherein the oil collecting space connecting to the crankcase conduit includes a valve which assumes its closed position with the booster and its closed position when the booster is stationary.
  • the micro-filter is so separated in this construction of the crankcase and is not subject to any restrictions, as regards its fine poredness and the size of the filter surface. These parameters can be adjusted for optimum separation of oil droplets and vapors, taking into account the allowable pressure drop.
  • the oil outlet of the oil collection chamber is closed, so that the oil collection chamber is only on its inlet-side line, so the actual vent line, communicating with the crankcase and also baufzzit only on this line with pressure.
  • the emptying of the oil collection chamber is done with stationary booster.
  • the valve is arranged in a gradient section of the associated line and designed as a check valve, wherein it is held by the pressure in the crankcase in its closed position.
  • the micro filter thus works automatically.
  • the check valve is a very smooth valve whose valve body is lifted by the low flow at the start of the post-compressor and brought into the closed position. The opening is carried out under the dead weight of the valve body and the weight of the oil column from above.
  • a safety valve which is connected to the line connecting the housing of the ultrafine filter on the inlet side with the crankcase, reliably prevents the build-up of an overpressure in the crankcase, if a fault should occur in the area of the ultrafine filter.
  • the fine filter on the outlet side at least one further filter, preferably an activated carbon filter downstream.
  • the residual oil content can thus be reduced to less than 0.005 mg / m 3 .
  • the booster on a crankcase 1 which forms an oil sump 2. Due to leakage of the booster builds up in the crankcase 1, a pressure that requires the vent.
  • a line 3 is connected to an oil filler neck 4 of the crankcase 1.
  • the oil filler neck 4 represents an extremely low-turbulence area of the crankcase. Accordingly, the mist discharged into the conduit 3 will not be excessively loaded with oil and oil vapors.
  • the line 3 leads to a micro-filter 5, which forms an oil collection chamber 6 on the input side.
  • the oil collection chamber 6 is connected via a line 7 to the crankcase 1, with the interposition of a check valve 8, which is arranged in a vertical section of the line 7.
  • the ultrafine filter 5 has a filter element which consists of a microfiber web.
  • the fine poredness of the ultrafine filter makes it possible to virtually completely free the oil supplied via the line 3 from the oil.
  • the surface of the ultrafine filter can be chosen so that the pressure loss is reduced to a level which ensures adequate and reliable ventilation of the crankcase 1.
  • the oil dripping from the fine filter 5 collects in the oil collecting space 6.
  • the pressure in the crankcase 1 keeps the check valve 8 closed, with the aid of a light spring. Will the re-compressor turned off, the pressure in the crankcase 1 is reduced via the line 3.
  • the check valve 8 opens, under the weight of its valve member and under the weight of the pending in the line 7 and the oil collection chamber 6 oil column. The oil collection chamber 6 thus empties into the crankcase. 1
  • the ultrafine filter 5 is followed by an activated carbon filter 9, which opens into the atmosphere.
  • the residual oil content can be reduced in this way to less than 0.005 mg / m 3 .
  • vent line does not necessarily have to be connected to the oil filler neck. However, it should depart from an area where there is little turbulence so that the vented mist contains as little oil as possible.
