Actuator device for brake system of motor car, has pump prominent boot line comprising flow resistor and liquid capacitor that is arranged between flow resistor and suction side of pump

摘要

The device has a motor pump (70) including a valve (80) between a liquid source and a suction side of the pump. Another valve (90) is arranged between the former valve and a suction side of a pump prominent boot line (54). Another pump prominent boot line (94) extends to the suction side of the former boot line through an output side of the former valve and/or an input side of the latter valve. The latter boot line comprises a flow resistor (100) and a liquid capacitor (106) that is arranged between the flow resistor and the suction side of the pump. The motor pump is a multi-piston pump e.g. six-piston pump and two-piston pump.
