Definitions

  • the invention relates to a device for assembling valve stem seals, which have a sealing part resting on the valve stem, an adhesive part that can be plugged onto the valve guide and a vulcanized, preferably metallic stiffening ring, and at least one spring concentrically surrounding the valve stem and one that can be connected to the valve stem Valve spring retainer.
  • DE-PS 32 22 356 discloses a device for mounting valve stem seals of the type mentioned. With the help of an assembly stamp, the valve stem seal with its adhesive part is pressed onto the tubular valve stem guide. The valve guide must be precisely machined to maintain a secure fit and function properly. In addition, the valve stem seal requires an axial stop for a clean seat on the valve guide or on the cylinder head. Only after the valve stem seal has been properly installed can the other parts, such as valve spring retainer, valve spring and valve cone pieces, be installed.
  • the object of the invention is to facilitate the assembly of valve stem seals, while at the same time reducing the assembly costs for the valve actuation parts, including valve stem seals.
  • valve stem seal is detachably connected directly or indirectly to the valve spring plate before assembly.
  • valve spring plate can take over the function as an assembly tool for the valve stem seal, so that a special assembly stamp is unnecessary.
  • valve spring plate usefully has an axial, cylindrical extension pointing in the direction of the valve stem seal.
  • This extension preferably has two cylindrical sections of different diameters which merge into one another, the cylindrical section having the smaller diameter facing the adhesive part of the valve stem seal.
  • the valve stem seal can be plugged into the axial extension of the valve spring retainer and is non-positively and releasably connected to it. It is therefore possible to simultaneously press the valve stem seal onto the valve guide while installing the valve spring retainer.
  • a disk is provided according to the prior art between the valve spring and the light metal support surface in order to bury the valve spring into the corresponding one Avoid light metal support surface.
  • the disc may or may not be connected to the valve stem seal via an axial extension.
  • the axial extension of the disk accommodates the valve stem seal and is releasably connected to the axial extension of the valve disk in the area of its axial extension.
  • the axial extension of the slide is bent radially at its end area facing the valve spring plate in the direction of the axial extension of the valve spring plate.
  • the axial extension of the disc has an axial stop.
  • the axial extensions are additionally drilled.
  • valve stem seal is no longer fixed by the valve guide, but by the valve spring, namely via the axial extension.
  • the connection of the disc and valve spring retainer also enables all individual parts, such as the disc, valve spring retainer, valve spring and valve stem seal, to be plugged onto the valve guide as an installation unit, regardless of whether the valve is already installed or not.
  • valve stem seals with washer is shown in the installed state.
  • the device is composed of the individual parts necessary for the valve train, such as valve cone piece 1, valve spring plate 2, valve spring 3, washer 4 and valve stem seal 5, to form an installation unit.
  • FIG. 2 shows an installation unit which can be mounted in the cylinder head without a washer 4.
  • the valve spring plate 2 has an axial extension 8 ⁇ which has two cylindrical sections of different diameters merging into one another, the cylindrical section having the smaller diameter facing the adhesive part of the valve stem seal 5.
  • the valve stem seal 5 can be inserted into the axial extension 8 ⁇ and releasably connected to it.
  • valve stem seal 5 is pressed into the axial extension 6 of the disk 4 and is limited in the insertion depth by an axial stop 7.
  • the axial stop 7 can be formed, for example, by radial bending or by punctually cutting in the extension 6.
  • the extension 6 is non-positively and releasably connected to the axial extension 8 of the valve spring plate 2 before installation in the cylinder head. In this state, the valve spring 3 is clamped between the disc 4 and the valve spring plate 2.
  • valve stem seal 5 and valve actuation parts prior to installation in the cylinder head now makes it possible to mount the installation unit in the cylinder head with only one handling machine.
  • valve spring plate 2 In order to make the installation unit functional, it is only necessary to axially load the valve spring plate 2 (FIG. 4). As a result, the press fit 9 is released and the previously inserted valve cone pieces 1 fall into the valve head groove 10.
  • the axial extensions 6, 8, 8 ⁇ are axially displaced so far against one another that their respective widening or tapering cross sections 11, 12 no longer touch (FIG 1). This ensures that the individual parts can move freely when assembled.
  • the axial extensions 6, 8 are additionally provided with bores 13, 13 ⁇ .
