High Pressure Pump/Return Pump

High pressure pumps/return pumps, combined into the hydraulic unit, are used for ASR V or ESP pressure supply and for recirculation of brake fluid during ABS, ASR V or ESP control. Silencers are built into each brake circuit to dampen delivery noise. Low pressure accumulator accommodates brake fluid returning during ABS/ASR/ESP/ETS pressure reduction phase and delivers it to high pressure pumps/return pumps.
