Pressure control valve position

The pressure control valve (3) is installed at the oil filter housing.

Pressure control valve task

If an excessive vacuum exists between charge air line and crankcase, the pressure control valve restricts the flow of the gas mixture.

Pressure control valve function

If a vacuum of more than 50 mbar exists in the charge air line, the connection to the crankcase is sealed off by a diaphragm. If the pressure in the crankcase rises, the diaphragm is opened by means of a spring.
