Crankcase bleeding (Racor)
Fumes are produced in the crankcase during engine operation. To protect the environment these fumes are
not allowed to escape into the atmosphere but are fed into a closed crankcase bleeding system. In this
crankcase bleeding system the filter performs important functions.
The fumes flowing into the filter first pass the pressure control valve which is mounted centrally in the top
part of the filter system. After passing the filter element the purified residual gases are fed to the suction line
between the suction air intake filter and the turbocharger.
The pressure regulator consists of a diaphragm valve loaded both sides. It controls the crankcase pressure
while at the same time vacuum pressures from the suction intake system settle at an upper limit. Pulsating
pressure peaks are limited as a result.
An optical indicator signals it is time to change the filter element.
The exchangeable and recyclable filter element consists of a micro glass fibre structure with a filter effect up
to 0.3 µm. This can be changed without tools due to quick-change catches. The filtered oil particles collect in
the sump of the filter casing and are fed back into the oil circuit by a return line.
A floor valve prevents gas getting in through the return line. The oil returns on exceeding the pressure differ-
ence between the filter and crankcase or at engine standstill.
