XE ENGINE, ENGINE BRAKE
General
DEB engaged
The solenoid valve (1) is activated. Lubricating oil
can pass to the hydraulic part of the DEB.
The pressure of the lubricating oil, at least 1.5
10
bar, moves the control valve (2) upwards against
the spring pressure and lifts the ball from its seat.
The high-pressure area of the DEB is now filled
with lubricating oil.
The oil causes the main piston (4) to move down,
until it rests on the set screw (9) of the rocker (8).
