Pressure pulsation damper for power-assisted steering system of motor vehicle, has oscillation body with pistons and chamber, which is filled with hydraulic fluid as spring element, where body is axially adjustably supported in housing

摘要

The damper (10) has a housing (12), which are in fluid communication with a power-assisted steering system. An oscillation body (14) has pistons (16, 18) and a chamber (20), which is filled with hydraulic fluid as spring element. The oscillation body is axially adjustably supported in the housing and is in effective connection with the power-assisted steering system. The oscillation body is axially movably supported in the housing, and the chamber is formed from a volume-variable material.
