Abstract (en)

[origin: EP1063391A2] The valve is retained in position by a valve spring held between spring plate and spring bearing. The adjustable valve spring bearing consists of meshing adjusting rings (102,103), which are turned in opposite directions. The inner ring (102) has a surface (104) to support the valve spring, and during turning against the outer ring is moved in direction of the valve axis. Both rings have elements esp. profiling, to prevent turning in the opposite direction.
