XE ENGINE, ENGINE BRAKE
General
If the main piston (4) continues to move up, this
movement is transferred hydraulically to the
10
operating piston (3).
The operating piston (3) moves downwards
against the spring pressure, opening one exhaust
valve.
In the case of loss of oil during operation, this will
automatically be compensated for by the control
valve (2).
