<p>A sealed liquid vibration damping apparatus comprising first and second connecting members (1,2) for connection respectively to two parts between which vibration is to be damped, an elastic body (3) between said first and second connecting members, a space (7,8) adapted to be filled with liquid between said elastic body and one of said connecting members, a partition wall (6) dividing the said liquid space into two liquid chambers (7,8), and an orifice (9) providing communication between said liquid chambers by way of the said partition wall, the said partition wall having a membrane portion (11) which can deform elastically in response to an input vibration and an abutment portion (12) formed integrally with said membrane portion and arranged to abut against a fixed part (14) when the membrane portion is elastically deformed. The reaction of the said abutment portion to the deformation of the said membrane portion varies non-linearly, and as a result the spring characteristic of the membrane portion is also non-linear. <IMAGE></p> |
