OIL PUMP
The oil pump is an external gear wheel pump with integrated pressure control valve. The valve opens at approximately 4.5 bar and controls the system pressure.
The pump is driven by the crankshaft and is 1.3 times faster than the crankshaft.
To ensure that the air is released from the oil system, a valve is located in the oil pump on the pressure side. During the build-up of pressure, air is routed out into the crankcase. This continues until the valve closes at approximately 0.2 bar.
