The high pressure pump consists of the fixed
stator about which the rotor rotates. Five
moving plungers are mounted in the rotor. The
stator and rotor are installed off-centre in the
pump housing. The plungers are guided
radially as the rotor rotates thus producing the
pump stroke motion.
The pressure relief valve integrated in the high
pressure pump opens in response to pressure
peaks in the high pressure system and opens
up a bypass to the oil pan.
The oil pressurized at 115 bar is routed via
three delivery lines to the two VANOS control
units and to the pressure accumulator.
