Definitions

  • the invention relates to an oil intake system for an internal combustion engine according to the preamble of claim 1.
  • the present invention is therefore based on the object to provide an oil intake system which the Avoids the disadvantages mentioned above and which in particular sensitive enough to also suck in air To be avoided reliably in the case of strong inclinations.
  • the oil intake system has at least three Oil intake pipes with at least four intake heads are connected to the oil pump via a suction pipe and the in the oil pan are arranged in such a way that the Internal combustion engine sucking air through in the oil intake pipes arranged control valves is prevented.
  • the control valves are advantageous than known per se Plate valves (DE-C-711575 or DE-B-1054292) are formed and arranged so that when "normal" horizontal Position of the oil pan are open. With extreme inclination the oil pan, however, are only those control valves opened, which are wetted with oil. All other control valves remain closed.
  • the oil intake system according to The present invention is in existing internal combustion engines easy to retrofit by simply using the oil pan and the normal suction basket are to be dismantled and the latter through the oil intake system according to the present invention is replace.
  • the regulation of the control valves can be mechanical or in another suitable manner.
  • An advantageous embodiment of the invention provides that three oil intake pipes are arranged in an H-shape and the have two suction heads on each side tube. By this arrangement ensures that in any tilt position There is enough oil at least at one corner of the oil pan is to ensure a suction of oil without air.
  • the intake manifold can be centered over a Flange with the connecting pipe between the two Side tubes can be arranged.
  • Oil intake system can by the X, Z or square arrangement of the oil intake pipes are formed. It is important that at all corners of the oil pan, in which the oil level can collect at inclined positions, there is at least one suction head. Depending on the shape the oil pan can do this, for example, by a triangular, polygonal or star - shaped arrangement of the Oil intake pipes may be possible.
  • Another advantageous embodiment of the present Invention provides that the suction heads against one Have the floor facing the suction opening. Without one such a design would have to have no air to suck, a minimum oil level the size of the Pipe diameter are available. An even lower oil level is only in accordance with the oil intake openings below the advantageous embodiment possible.
  • an advantageous embodiment provides that a check valve at the transition between the intake manifold and Oil pump seat is arranged to idle the Intake manifold and pump room closed when the engine is stopped prevent.
  • Fig. 1 is an embodiment of an inventive Oil intake system shown, which in an oil pan 24th is installed.
  • the oil pan 24 is located in one Oblique position, so that the oil level S1 only the Suction head 19 of the tube 28 is washed around.
  • the H-shaped trained oil intake system consists of three Oil intake pipes 26, 27, 28, each one axially displaceable sliding rod 1, 2, 3 have valve plates 4 at each of their two ends, 5, 6, 7, 8, 9 are arranged.
  • the valves of the oil intake pipe 27 are open, although they are not wet with oil. To suck in air This is prevented by valve plate 4 and valve seat 30 formed valve of the tube 26 closed and that on arranged at the other end of the push rod Valve plate 5 and valve seat 31 formed valve opened.
  • the valve rod 1 is via the axial bearings 10, 11 axially displaceable.
  • the oil intake pipe 28 has how already mentioned, the opened by valve plate 8 and Valve seat 34 formed control valve and by Valve plate 9 and valve seat 35 formed closed Control valve on. Both valve plates 8, 9 are on the axially displaceable sliding rod 3 connected in the bearings 14, 15 is movably mounted.
  • the two Side tubes 27, 28 also have filter screens 20, 21, 22, 23 on.
  • the bearings 12, 13 of the slide rod 2 in Tube 27 shown.
  • At the ends of the slide bar 2 are valve plates 6, 7 with the valve seats 32, 33 arranged.
  • the oil flow is shown in Fig. 1 by the arrows 36.
  • the outlet opening 29 is also shown in FIG. 1, which are arranged centrally on the top of the suction pipe 26 is and with the suction pipe 43, not shown, also Oil pump 45, not shown, is connected.
  • the inclined position shown moves the valve plates 5 and 8 due to gravity in their open position, the valve plates 4 and 9 via the slide rods 1 and 3 are moved to their closed position. This ensures that in the now only on Intake head 19 open intake system no air is sucked in becomes.
  • the position of the valves in the oil intake pipe 27 is in the oblique position shown in Fig. 1 irrelevant, since the Tube 27 completely through the closed valve plate 4 from remaining oil intake system and thus in particular from the Exit opening 29 is uncoupled.
  • FIG. 2 schematically shows the oil intake system from FIG. 1 in a side cut, which is on the crankcase 52 attached oil pan 24 is in the horizontal position, i.e. the oil level S2 is parallel to the tub floor 40.
  • the valve plates 4, 5 of the tube 26 both open, i.e. lifted off the valve seats 30, 31.
  • the pipes 27 and 27 connected to pipe 26 via flanges 25 28 and the slide rods 2, 3 are in section shown.
  • Between the Crankcase 52 and the oil pan 24 is also one Fixed support plate 41, which has a plurality of openings 42, that allow unhindered oil flow.
  • the plate 41 has a suction pipe 43 for an oil pump 45, as shown, a gear pump, the Housing is attached to the plate 41. That from the pump 45 oil pumped to the point of use of the machine into a pressure pipe 46.
  • the suction pipe 43 is at the lower end formed as a flange 44 which for attaching a elongated, parallel to the bottom 40 of the tub 24 arranged, hollow and cylindrical tube 26 is used.
  • the Tube 26 has a mounting flange for this purpose 49. Inside the flange 44 is on a pin 50 tiltable plate valve 51 is provided, which in the rest position the machine rests on the flange 49 and the Reflux of the oil from the suction pipe 43 and the pump 45 prevented.
  • a slide rod 1 Slidably mounted axially parallel.
  • two bearings 10, 11, e.g. Ball bearing, in two perforated cross flanges 47, 48 of the Tube 26 provided.
  • the rod 1 carries one at each end flat valve plate 4, 5, each with a Valve seat 30, 31 formed annular surface at each end of the tube 26 cooperates.
  • Fig. 3 shows the oil intake system according to FIG. 2, but in tilted position so that the oil level S3 in the right lower corner.
  • This is the case, for example, when a vehicle drives up a steep slope and the Oil pan 24 an approximately at an angle of 45 ° to the horizontal assumes an inclined position.
  • the oil collects in the lower right corner of the oil pan 24, the oil level S3 again lies horizontally.
  • the rod 1 takes Effect of gravity the position shown in Fig. 2 in which the valve plate 5 from the valve seat 31 is moved away and the oil supply to the pump 45 via that in oil fully immersed tube 28 and the arranged thereon Suction heads 18, 19 takes place.
  • the oil pump 45 can also in this extreme inclination of a vehicle and thus also the oil pan 24 of the internal combustion engine no air, but just suck in oil.
