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.
  • 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, via 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.
  • Such a pressure control valve is usually flanged to the side of the engine and with appropriate Connection lines connected to the crankcase or fresh air inlet.
  • Such valves are known for example from the publication of the company FILTERWERK MANN + HUMMEL GMBH No. VKD 7032.
  • the invention is therefore based on the object of avoiding the disadvantages mentioned and of creating a pressure regulating 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 required 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.
  • the blow-by gas passing through the pressure control valve can be fed 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.
  • FIG. 1 shows schematically an engine block 10 on which a valve combination 11 is arranged as a unit.
  • An air filter 14 is arranged on the engine block 10 via an intake manifold 12 and a throttle valve 13, the raw air entering the air filter housing via the damper tube 15 and reaching the clean air space 17 through the air filter insert 16.
  • 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, for example, provided 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 engine crankcase 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.
  • the hollow body 18 is tapered downwards and is designed as a tube 27 which receives the oil dipstick 22 and also serves as a flow tube for the oil to be filled or returned.
  • This tube 27 is flanged directly to the engine block 10.
  • FIG. 2 shows the pressure control valve in a sectional illustration.
  • This consists of a housing 28 which is integrated directly into the hollow body 18.
  • the housing 28 is composed of a pot-shaped housing lower part 29 and a housing cover 30 fastened to it.
  • the inlet connection of the line 24b opens into the housing lower part 29, through which the blow-by gases from the crankcase are introduced into the valve.
  • 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 membrane valve body 33 is located within the valve 23. The outer edge of the diaphragm valve body is clamped between the lower housing part 29 and the housing cover 30. This diaphragm valve body 33 divides the valve housing into a valve chamber 34 and a ventilation chamber 35. The ventilation chamber 35 communicates with the atmosphere via a ventilation channel 36.
  • 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 a 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 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 in this figure offset 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.
  • FIG. 3 shows a valve body with a double valve for connection to the intake manifold, in which significantly higher negative pressures occur than in the filter (approx. 800 mbar).
  • a similar double valve is known from DE patent 30 32 243.
  • the double valve sits on a cylindrical hollow body 18 which is flanged to the tube 27.
  • This tube also serves as a drain connector 31.
  • a branch 21 is provided for an oil dipstick, not shown here.
  • the double valve consists of two housing covers 30, under which there are ventilation chambers 35. These ventilation chambers are closed by two diaphragm valve bodies 33. These valve bodies 33 are held in the position shown by means of two return springs 37 in the absence of or a slight negative pressure in the intake manifold. The return springs are in turn supported on a central valve part which has two valve seats 46, 47.
  • the valve part 45 is provided with an outlet 24c, which forms the line to the intake manifold.
  • the connecting piece for the line 24b to the crankcase is located below the pressure control valve.
  • the oil-loaded crankcase gases are introduced into the hollow body 18 through this line.
  • a large part of the entrained oil is deposited on the inner wall of the hollow body 18, so that the blow-by gases flowing into the pressure control valve through the pipe extension 43 are substantially freed from the oil.
  • An oil filler neck 44 is located above the pressure control valve 23. This can be closed with a cover, not shown here.
  • FIG. 4 shows an alternative to the valve combination shown in FIG. 2.
  • the pressure control valve 23 in the lid 20 which closes the opening for filling the oil.
  • no further branch is required for a fill opening.
  • the valve combination 11, as shown here, is characterized by a particularly small space requirement.
  • 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.
  • a ventilation chamber 35 is supplied with the atmospheric pressure of the surroundings via a ventilation channel 36.
  • the outlet line 24a which is attached to the pressure regulating valve 23, is designed to be flexible, so that problem-free removal of the cover 20 is ensured when filling with oil.
