Pressure medium transitions are only in the area of the openings 27, 34, 36, 38 and 40 possible.
  • the depressions 33 and 37 on the one hand and 35, 39 and 41 on the other hand thus form together with the seal 20 and the openings 27, 34, 36, 38 and 40 a channel 42, which is connected to the control connection of the control valve 30.
  • This channel 42 is in the area of the tappet guides 22b of a respective cylinder via a channel 43b in the central web 21 and an outgoing oblique bore 44b with the respective tappet guide 22b and is used for pressure medium and Lubricant supply to the cup tappets 45b shown schematically in FIG. 6.
  • These tappets can be used as conventional tappets known per se or as also known switchable or switchable tappets can be formed.
  • Switchable bucket tappet is to be understood as one with which Valve stroke of the associated gas exchange valve switched on or off completely can be.
  • Switchable bucket tappets mean one with which the valve lift of the associated gas exchange valve varies in at least two stages can be.
  • each of the three cylinder bores 5 or bores 23 Three channels 43a, 43c and 43d each open into this recess 53. Of these Channels in the central web 21 each have an oblique bore 44a, 44c and 44d to supply the associated ram guide 22a, 22c, 22d or the Cup tappet 45a, 45c and 45d is used.
  • These ram guides can also be used known plunger elements in switchable, switchable or non-switchable Execution can be used. It can make sense if, for example, that each assigned inlet valve with a switchable or switchable Tappet element is provided while the associated exhaust valves are not switchable plunger elements are operated.
  • the depression 53 thus forms, together with the seal 20, a channel 54 which is connected to the control port of the second control valve 50 is connected.
  • This channel 54 serves together with the channels 43a, 43c and 43d and the oblique bores 44a, 44c and 44d the pressure and lubricant supply to the tappet guides 22a, 22c and 22d or the tappet 45a, 45c and 45d.
  • the ring channel 29 on the first control valve 30 is through a bore 55 with a short Recess 56 connected in the flange surface 19.

  • the tappets 45 a and 45 b are each switchable elements trained (stroke switchover or lift cutoff).
  • the exhaust valves associated tappets 45c and 45d are not in this embodiment switchable.
  • the oil pump 60 of the internal combustion engine delivers oil from the oil pan 61der Internal combustion engine via a riser 62 in the cylinder block 1 in the Cylinder head arrangement.
  • the two switching valves 30 and 50 are on previously pressure described on the input side. In the unswitched The condition of both switching valves is the input side with the check valve 31 or 51 connected.
  • the check valves are designed so that they are only at Open when a specified pressure is exceeded. This opening pressure is lower than the switching pressure of the bucket tappet or the one integrated in the circuit Switching elements. Together with a throttle line 63 or 64 between the Riser 62 and the channel 42 and 54 is thus ensured that one for the Lubrication does not require pressure within the cylinder head assembly is undercut.

It is easily possible for other consumers within the To supply cylinder head assembly with pressure medium or lubricant. You can for example, all lubrication points in the area of the valve train. It is still possible by separating the individual channels or channel sections to supply different consumers with pressure medium or lubricant. This can in particular switchable valve lift transmission elements, such as Rocker arm, rocker arm or the like. It is still possible, alternatively or in addition, the pressure supply of valve phase control elements via one of these Channels or channel sections.
  • the arrangement offers different channels and channel sections within the flange level or within the flange surfaces separated by the seal Possibility to lubricate different consumers independently or to supply pressure medium. It is in contrast to what is shown here Embodiment also possible, the lubricating oil supply and pressure control switchable consumers (e.g. switchable valve lift transmission elements) independently from each other by separate exposure via separate channels or lines to make. This consumer is supplied with lubricating oil via the first lines provided. Hydraulic can then also be used via these first lines Valve clearance compensation elements are applied. Via a second line then the pressure control of switching elements take place. These lines are then for example, each connected to one of the channels, so that pressure and Volume flow independently of each other to the different requirements can be adjusted.
