Vibration damping device with part that partially limits a fluid-filled pressure chamber and oscillates pneumatically

摘要

Fluid-filled vibration damping device (10, 70) wherein two mutually spaced-apart mounting members (12, 14; 72, 74) are connected by an elastic body (16; 76), which cooperates with a movable member (34, 36, 38; 130, 134) to at least partially defines a fluid-filled pressure-receiving chamber (40; 98), and the movable member partially defines a working air chamber (54; 132) on its side remote from the pressure-receiving chamber and is oscillated by a periodic change of an air pressure applied to the working air chamber through a pressure inlet (56, 58; 138), so as to cause a periodic change of the pressure of the fluid in the corresponding pressure-receiving chamber, for thereby controlling a damping characteristic of the damping device.
