  • the securing element can be formed in a simple and cost-effective manner by a conventional locking ring but also by lock washers or snap rings or corresponding components, which can preferably cooperate with a circumferential groove in the valve stem. But also the use of clamping cones or split clamping cones is possible.
  • valve spring assembly may comprise a valve stem seal, which may preferably cooperate with the valve spring plate such that it is detachably fixable to this.
  • valve stem seal can be mounted together with the valve spring assembly. Thereafter, it can be separated from this or the valve spring plate to be set at its operating position.
  • a recess or a projection may be provided on the valve spring plate, with which the valve stem seal can enter a clamp connection. This is designed so that it can be solved after the valve stem seal has assumed its operating position on the cylinder head and is secured thereto, for example, by a clamp or otherwise frictionally engaged or otherwise.
  • a valve spring retainer for use in a described valve spring assembly may be purchased as a single part and assembled in a pre-assembly station with the remaining components to the valve spring assembly and then assembled together with it as a mounting unit on a valve stem of an internal combustion engine.
  • a method of assembling a valve spring assembly is suitable for both manual and automated assembly. Due to the combination of several components to a valve spring assembly, which can be brought as a preassembled unit to the assembly site, the assembly process can be accelerated or carried out an assembly by means of a machine, for example with a magazine or an automated feed.
  • FIG. 1 shows a valve stem 10 of an intake or exhaust valve (not shown in more detail) which extends through a cylinder head 12 of an internal combustion engine, which is shown only schematically.
  • a valve spring assembly 14 in disassembled from the valve stem 10 and not attached to the valve stem 10 shown state.
