Definitions

  • the invention relates to a pressure control valve for crankcase ventilation on an internal combustion engine according to the preamble of the main claims, as known from DE-A-27 02 621.
  • Such pressure control valves for crankcase ventilation are arranged, for example, in the ventilation line between the crankcase and intake air filter or engine intake manifold. Because of these pressure control valves, there is a closed connection between the crankcase and the intake side of the engine, through which the blow-by gases are drawn off and fed back into the combustion process.
  • the pressure control valve ensures that a certain pressure in the crankcase is not undercut. A constantly low vacuum in the crankcase prevents blow-by gas from escaping outdoors.
  • the invention is therefore based on the object of avoiding the disadvantages mentioned and of creating a pressure control valve which enables a better overview of at least some of the components arranged on the engine. This object is achieved on the basis of the preamble of the main claims by their characterizing features.
  • This unit namely the pressure control valve, the oil filler neck and the oil dipstick, forms the component necessary for the oil supply and monitoring, which is flange-mounted on the side of the engine, for example, and avoids costly individual parts.
  • This unit can z. B. are made of a temperature-resistant plastic and can be flanged to the engine block where the opening for the oil dipstick is provided. The oil to be filled in at the filler neck passes through this opening into the crankcase, so that an additional filler opening is unnecessary here.
  • the oil entrained by the blow-by gases which is separated from the blow-by gases in the pressure control valve, can also be returned via this opening.
  • Another embodiment of the invention provides claim two.
  • An advantage of this solution can be seen in the fact that the pressure control valve is integrated in the cover of the oil filler neck. An additional branch or an additional oil filler neck is thus unnecessary. Since the cover in this case is connected to the air supply of the engine via a flexible line, there is the further advantage that the cover cannot be removed from the engine compartment and is therefore not lost.
  • the blow-by gas passing through the pressure control valve can be supplied to the clean air side of the filter according to a further development of the invention.
  • a pressure control valve can also be found, for example, in DE utility model 78 22 216. Such a pressure control valve has a very compact design. According to a development of the invention, such a pressure control valve is used to enable this combination of oil filler neck, oil dipstick and blow-by gas discharge line.
  • the valve combination 11 consists of a cylindrical hollow body 18, on which a branch 19 is located.
  • This branch is designed as an oil filler neck and can be closed with a cover 20.
  • the lid is provided, for example, with a known bayonet catch.
  • the cylindrical hollow body 18 has a further branch 21. In this there is an oil dipstick 22.
  • a pressure control valve 23 is arranged on the top of the hollow body 18 and closes off the hollow body at the top.
  • a line 24b via which the blow-by gases of the crankcase of the engine are fed to the valve, opens onto this pressure control valve.
  • An outlet line 24a serves to discharge the blow-by gases and is connected to the clean air side of the air filter.
  • a flame arrester 26 is arranged at the entry of this outlet line 24a into the air filter 14.
  • a drain connection 31 leads to the outlet line 24a shown in FIG.
  • the nozzle end of the drain connector 31, which is arranged centrally within the valve housing 28, is designed as a valve seat 32.
  • a return spring 37 is supported with one end face on the bottom of the lower housing part 29 and rests with the other end face against the diaphragm valve body 33, which it under appropriate pressure conditions, for. B. at standstill of the connected internal combustion engine, in the position shown in Figure 2. From a certain negative pressure in the intake system of the internal combustion engine, the Diaphragm valve body 33 close the valve seat 32 so that this high negative pressure does not continue into the crankcase of the internal combustion engine. The valve closes the crankcase ventilation until a sufficiently high pressure is created by the newly produced blow-by gas, which opens the valve again.
  • the branch 19 was drawn offset in this figure by 90 degrees to better illustrate the pressure control valve.
  • the lid is omitted for the sake of simplicity.
  • the entire hollow body 18 can for example be made of a plastic.
  • the lower housing part 29 of the pressure control valve 23 is integrated at the same time during production, for example in an injection molding process.
  • the blow-by gas escaping from the crankcase is fed to the hollow body 18 via the connection 38.
  • This blow-by gas reaches the valve chamber 34 via an opening 39 in the cover 20.
  • a diaphragm valve body 33 which is held in the position shown by a return spring 37.
  • the return spring 37 encloses the valve seat 32, which is formed by the tubular extension 40.
