Liquid damping type vibro-isolating mount

Abstract

Abstract PURPOSE:To avoid rapid rise of liquid pressure so as to attempt easement of impact by providing a switching passage at a partitioning member by means of a fixed side supporting member and a mobile side partitioning plate, in a chamber filled with liquid. CONSTITUTION:A chamber of a closed structure is formed in a body 1 and partitioned into two chambers 8 and 9 by a partitioning member 7. The partitioning member 7 is constituted by a partitioning plate 10 having a mobile plate 19 and a ring-shaped supporting member 11, and the mobile plate 19 is engagingly locked on the partitioning plate 10. Moreover, the partitioning plate 10 and the supporting member 11 have a switching passage 16 and, an orifice 15 is provided at the ring part of the supporting member 11. When this vibro- isolating mount receives an input accompanied by its rapid change, the partitioning plate 10 moves against a spring 14 toward the chamber 9 opposite to the chamber 8 in which pressure has rapidly become positive, and the switching passage 16 is opened, so that transfer of liquid between the both chambers 8 and 9 is executed rapidly and any increase in a dynamic spring constant is prevented in advance.
