Definitions

  • the invention relates to a valve holder for a lift valve of an internal combustion engine according to the mentioned in the preamble of claim 1. Art.
  • the invention is based on German Offenlegungsschrift 20 14 575.
  • a valve control arrangement for internal combustion engines with an overhead Camshaft shown.
  • the cam of a rotating camshaft actuated at this arrangement, a rocker arm, in turn, the cylinder head side in a ball joint is stored.
  • the ball joint side remote from the end of the rocker arm transfers the lifting movement via a pressure plate with side cheeks on Lift valve.
  • the valve stem of the lift valve is controlled by valve cone elements against the Spring force of valve springs, which press against the spring plate, held in this.
  • the spring plate encloses the pressure element between the rocker arm and the valve stem is arranged radially. Part of the cheeks of the printing plate are in Closing direction of the globe valve from the hole in the spring plate, in which they are arranged is out.
  • a disadvantage of this arrangement is the high design of the valve disk and the Pressure plate and thus caused the large moving mass of the valve train.
  • the object of the invention is a flatter design of valve plate and pressure plate to minimize the moving mass of the valve train to realize, with a tilting the pressure plate during assembly of the valve train parts as well as during service work is safely prevented.
  • This object is achieved by the characterizing part of the claim 1 solved.
  • This arrangement shortens the length of the valve disk in the closing direction the lift valve optimal, which space is gained and the moving Masses are reduced in the valve train. Furthermore, falling out of the printing plate prevented by tilting in the hole. Valve train or engine damage due to fallen printing plates are due to the engine compartment reliably prevented.
  • Figure 1 shows a sectional view of a valve holder 1.
  • a pressure plate 6 At the end of the valve stem 2 is a pressure plate 6.
  • she is in a, to the conical bore 8 coaxial cylindrical bore 9, the inner diameter of which is greater than the largest inner diameter of the conical Bore 8 is held radially.
  • On the outer circumference of the valve stem 2 are three Ring grooves 10, 10 'incorporated radially to a Hubventilachse 11.
  • valve stem 2 in the conical bore. 8 from the side facing away from the pressure plate 6 introduced. Subsequently, will the valve plate 4 with a special tool against the spring force of the valve spring. 5 pressed, so that the valve stem 2 at least by its guide length in the spring plate 4 protrudes beyond the edge of the bore 9.
  • the two valve cone elements 3, 3 ' inserted into the annular grooves 10, 10' on the valve stem 2. Then the contact pressure of the special tool is reduced against the spring force, so that the valve stem 2 with the two valve cone elements 3, 3 'with their slide conical outer circumference in the conical bore 8. Due to the Spring force of the valve spring 5 now wedge the valve cone elements 3, 3 'in the conical bore 8.
  • valve cone elements 3, 3 'and the pressure plate 6 reliably prevents them from tilting.
  • the number of annular grooves 10 on the valve stem 2, in which the valve cone elements 3, 3 'engage vary. Likewise more than two valve cone elements 3, 3 'to be installed. For the easier and better Mounting the pressure plate 6 can slip on the cylindrical bore 9 are attached.
