Function
Oil flows from the oil inlet (012) through the top cylinder half (002) into the two annular spaces
(003). When the crankshaft (004) moves in an axial direction, the pressure of the oil in the
compressed annular space (003) increases. This makes the oil slowly flow through the small holes
in the control plate (001) into the other annular space (003). This slow oil flow decreases the axial
vibrations. When the pressure is equal again in the two annular spaces (003), the oil flow stops.
The constant oil flow through the vent bore in the top cylinder half (002) keeps air away from the
annular spaces (003).
The small oil leakage through the gap of the large sealing rings (005) drains into the crankcase.

Axial vibration damper monitor
The axial vibration damper monitor monitors the oil pressure in the two annular spaces (003,
) of the axial vibration damper. The needle valve (004,
prevent fast movement of the pointer in the pressure gauges (001).
