Definitions

  • the invention relates to one according to the preamble features of the claim 1 designed method for operating a hydraulically controlled / regulated Camshaft adjusting device for internal combustion engines.
  • EP-B 0 245 791 describes one operated according to the generic method Camshaft adjusting device known in which the mechanical actuating device by appropriate choice of the direction of a helical or helical toothing is designed relative to the direction of rotation of the camshaft so that at Failure of the control / regulating hydraulics in the late position to the stop brought. This is to ensure engine operation when the internal combustion engine is cold started with the generic hydraulic system principally to quickly undo towards early adjustment, however, e.g. Early adjustment to be achieved within one second no longer ensured during longer breaks in operation of the internal combustion engine due to leaks in one of the two valves, the pressure level in the pressure accumulator is reduced.
  • the invention has for its object the generic operating method for a camshaft adjusting device with a simple structure to improve that a rapid early adjustment of the camshaft can be achieved depending on the start is.
  • valve-controlled pressure accumulator connectable to the hydraulic circuit advantageously, with a simple structure, a method for the fastest possible Early adjustment of the camshaft achieved when starting the internal combustion engine.
  • the method according to the invention is schematic with reference to one in the drawing Hydraulic circuit shown for a camshaft adjusting device described.
  • a camshaft adjusting device 1 of a not shown Internal combustion engine comprises a mechanical actuating device 2 and one hydraulic actuating device 3.
  • the mechanical actuating device 2 effects about their teeth 4 and 5 according to the drive direction according to the arrow "A" of the driven wheel 6 when the hydraulic actuating device 3 is ineffective a late position of a camshaft 7, a piston 8 of the Actuator 3 assumes an end position "B".
  • the pump 9, supply line 11, return line 12 and 4/3-way valve 13 in essentially formed hydraulic circuit 16 is upstream of the check valve 10 A pressure accumulator 19 via a line 17 and a 2/2-way valve 18 connected.
  • the one arranged in series with the pressure accumulator 19 Electromagnetically actuated 2/2-way valve 18 has in the with Pump-side hydraulic circuit 16 connected pressure accumulator inlet path 17 'a seat valve 20.
  • the seat valve 20 serves to retain Pressure medium from the hydraulic circuit 16 in the pressure accumulator 19.
  • control unit 21 denotes an electronic control unit, which is connected via signal lines 22 is connected to an ignition system 23.
  • Another control line 24 is connected the electromagnetically actuated 4/3-way valve 13 connected such that the Inlet line 11 with the control chamber 14 in the late position of the camshaft 7 standing piston 8 is connectable.
  • the control unit 21 further signal line 25 to the electromagnetically actuated 2/2-way valve 18, to close the pressure accumulator 19 with the inlet line 11 via its outlet path 17 " connect.
