Pulsation damper for motor vehicle`s hydraulic system, has pipeline for conveying fluid and arranged between inlet and outlet, and set of chambers with openings, where chambers have different absorption characteristics based on frequency

摘要

The pulsation damper (1) has an inlet (5) for input of fluid, and an outlet (7) for outputting the fluid. A pipeline (8) conveying the fluid is arranged between the inlet and the outlet, and a set of chambers (10-13) includes openings (14-17), where the chambers have different absorption characteristics based on frequency. A control piston (9), an actuator and a control device are designed and arranged such that the individual openings are connected with the pipeline by the control piston, the actuator and the control device.
