Exhaust Valve Air Spring Pipes

The exhaust valve is opened hydraulically and the
closing force is provided by an ‘air spring’ which
leaves the valve spindle free to rotate, see Fig.
13.03.02.

The item Nos. refer to ‘Guidance values automation’
The piping is delivered with and fitted onto the engine
