Definitions

  • the invention relates to a conditioning unit for lubricating oil, in particular in one Motor vehicle, according to the preamble of the main claim.
  • Conditioning units for lubricating oil in a motor vehicle are known, in which an oil filter assembly with an oil filter bypass valve and an oil cooler separately are housed in the engine compartment of the motor vehicle. This arrangement leads to a large manufacturing effort and does not allow optimal coordination of the individual components each other.
  • a filter device in which an exchangeable Filter element is provided on a carrier.
  • the carrier includes in addition to the corresponding Supply and discharge lines a valve for the filter element and a another valve.
  • a disadvantage of the known device can be seen in that in addition other elements such as radiator, radiator bypass valve and other must be provided, which requires considerable effort on liquid lines mean.
  • the invention has for its object a conditioning unit of the type specified Kind of training so that simple manufacture and compact construction is achievable.
  • the conditioning unit for lubricating oil according to the invention with a filter arrangement for the lubricating oil, with a replaceable, metal-free filter element, a filter bypass valve and an oil cooler in the oil circuit of the Lubricating oil advantageously has a base body on which the filter assembly with the filter bypass valve is attached. With this basic body is a good coordinated system for conditioning, i.e. Filtering and cooling of the lubricating oil possible. To is advantageously also on the base body Oil cooler, an oil-coolant heat exchanger and another Bypass valve for the oil-coolant heat exchanger added.
  • conditioning unit easy to manufacture possible that the main body of the conditioning unit designed as an aluminum or plastic casting is and with connections and internal channels for Guide the lubricating oil and the coolant is provided.
  • the housing is for easy maintenance of the conditioning unit provide the filter assembly with an oil drain plug, taking the oil drain plug with a shoulder support on the thread outlet to protect against overturning is provided. Also a drainage option for that too coolant circulating in the base body is open easily possible if there is a drain element on the base body for the coolant is attached.
  • the conditioning unit according to the invention thus allows with a simple method of manufacture an extremely compact structure, so that in particular the optimal integration a filter arrangement in the units of the internal combustion engine of a motor vehicle in a simple way is possible.
  • FIG. 1 is a base body 1 of a conditioning unit shown for the lubricating oil of a motor vehicle, wherein the oil to be filtered through in the conditioning unit an oil cooler 2 is passed into a filter arrangement 3 (Arrow 4). Located on the base body 1 of the conditioning unit there is still an inlet for a coolant (arrow 5).
  • the coolant usually the cooling water for the Internal combustion engine, is through an oil-coolant heat exchanger 6 directed to an outlet 7.
  • an oil-coolant heat exchanger 6 directed to an outlet 7.
  • an oil-coolant heat exchanger 6 directed to an outlet 7.
  • another bypass valve not visible in FIG. 1 available for the oil-coolant heat exchanger 6.
  • the filter arrangement 3 is a metal-free filter cartridge 8 arranged as a filter element on a central tube 9. Through the filter paper layers of the filter cartridge 8 and through Openings in the center tube 9, the oil in the interior of the Middle tube 9 and then to the exit (arrow 10) of the conditioning unit 1.
  • a bypass valve 11 is arranged in the central tube 9, through which an oil flow through bypass channels (arrows 12) the filter cartridge 8 are passed over to the exit can, for example, if the lubricating oil is under pressure of 2.5 bar.
  • An outlet screw 13 for the lubricating oil is via an Allen key 14 from the housing of the filter arrangement 3 can be unscrewed, which means that in the conditioning unit 1 existing, possibly to be replaced Lubricating oil can be drained (arrow 15).
  • the Imbus 14 is dimensioned so that when screwing in the Outlet screw 13 can be turned and thus a Cracking due to excessive torque in the outlet screw 13 is prevented from plastic.
  • the power which acts on the thread is also a Shoulder support caught in the thread area.
  • the Outlet screw 13 is without the use of metal inserts designed with a plastic saw thread.
  • FIG. 2 From Figure 2 is a plan view of the base body 1 with the filter arrangement 3 and the oil cooler 2 can be seen.
  • the Coolant enters the base body 1 according to arrow 5 and flows through the oil-coolant heat exchanger, which cannot be seen in detail here 6.
  • the lubricating oil flows according to the arrow 4 in the base body 1 and flows through it through channels integrated in the base body 1 and the Oil cooler 2 and the filter arrangement, as shown in the figure 1 described.
  • a bypass valve 16 for bypassing the oil-coolant heat exchanger 6 for certain Operating conditions, for example for opening at an overpressure of 1 bar.
  • FIG 3 is the basic flow of the lubricating oil and of the coolant shown in context.
  • the lubricating oil from an oil pan 18 (arrow 4) and through the base body 1 with the oil-coolant heat exchanger 6 funded.
  • the coolant also through the base body 1 and passed the oil-coolant heat exchanger 6, here there is also a drain element 19 for the coolant is.
  • the bypass valve 16 is switched.
  • the lubricating oil will then through the filter element 8, or via the bypass valve 11 to an internal combustion engine 20 and then promoted again in the oil pan 18.
  • the outlet screw 13 is the outlet screw 13 provided for the Lube oil in the filter assembly 3.
