Title: Vibration damper
Inventor: TASHIRO KATSUMI
IPC: F16F13/26
Filed: 2003-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To introduce negative pressure and atmospheric pressure alternately to a balance chamber with sufficient precision to input vibration to be synchronized with the input vibration when any is inputted at high frequency, and prevent early failure of a change-over valve for alternately introducing negative pressure and atmospheric pressure to the balance chamber.  <P>SOLUTION: In this vibration damper 10, one of N-pieces of the change-over valves 40 connected to the balance chamber 24 of a controller 56 is selectively actuated in order synchronously with input vibration from a vibration generating part. Negative pressure and atmospheric pressure are alternately introduced through the change-over valve 40 into the balance chamber 24. As inner pressure (air pressure) in the balance chamber 24 is changed synchronously with the input vibration, inner volume is changed, and liquid pressure fluctuation (to rise) in a pressure receiving liquid chamber generated at the time of vibration input can be absorbed due to volume change of the balance chamber 24. Since N-pieces of the change-over valves 40 are connected to the balance chamber 24, the actuation cycle of each change-over valve 40 can be delayed to about N-times compared to a case of using a single change-over valve.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
