ABSTRACT:
A vibration isolator for mounting a vibrating body on a structural body includes a first attachment member adapted to be connected to the vibrating body, a second attachment member adapted to be connected to the structural body, and an elastically deformable resilient member fixed to and interconnecting the first and second attachment members, the resilient member being elastically deformable in response to relative movement of the first attachment member with respect to the second attachment member. The vibration isolator has a first chamber defined at least partly by the resilient member and having a volume variable dependent on elastic deformation of the resilient member, and a second chamber operatively communicating with the first chamber through an operative communication structure and having a volume variable dependent on variation of the volume of the first chamber, the first and second chambers being filled with a liquid. The operative communication structure includes a flexible film dividing the first and second chambers from each other and an arrangement for limiting movement of the flexible film.
