WIPO Patent Application WO/2002/016798

Kind Code:

A1

Abstract:

A double orifice type liquid sealed vibration control device, comprising a partition part (10) fitted between a vibration control base body (2) and a first diaphragm (4) connected to each other through a main body metal plate (1) and having a partition main member (15) forming a first orifice (13), a partition plate member (16) forming a second auxiliary liquid chamber (9) and a second orifice (14), and a receiving plate for partition (17) forming the first orifice (13), wherein an access port (26) on a main liquid chamber side is used commonly for both orifices (13) and (14), and the first orifice (13) is branched from a part of the passage of the second orifice (14) with less liquid passing resistance than the first orifice to set two compact orifices, whereby a variation and a change in characteristics can be compensated for easily by the adjustment of the circumferential positions of partition part component members (15), (16), and (17).
