摘要： There is provided a switchable liquid-filled vibration isolating mount that damps each of shaking vibration and idling vibration by opening and closing an orifice, and that maintain a stable and reliable operation for a long period. First and second fixtures are joined together by a vibration isolating base body to form an inner space defined thereby. This inner space is partitioned by a partitioner and first and second diaphragms to form main and sub-liquid chambers that are communicating with each other via inner and outer orifices. A space between the first and second diaphragms is an equilibrium chamber. A space between the second diaphragm and second fixture is a switching chamber into which either of an atmospheric pressure and a reduced pressure is selectively introduced. The inner orifice is an opening of the partitioner. The first diaphragm has in its central portion a valve body that has a projection always inserted in the inner orifice all the time the orifice is opened or occluded.

摘要： The present invention aims at providing a liquid sealed type vibration isolator capable of positioning a partition excellently with the construction of the partition simplified, and maintaining stable damping characteristics of an orifice. To meet the requirements, an outer circumferential portion of the partition forming the orifice is made so that the outer circumferential portion defines at least a part of one or two sides of a cross section of the orifice, and a positioning device formed of a partition press fitting or inserting structure with respect to a groove, or a partition engaging structure is provided in a joint portion between the partition and the other orifice forming member with the construction of the partition simplified, whereby it is rendered possible to improve the accuracy of the partition and obtain a desired cross section of the orifice. When an elastic film is provided on the partition so as to reduce a dynamic spring constant in a high-frequency region, the steps of forming one cylindrical partition and a disc type elastic film separately, forming a positioning bore in a lower surface of a circumferential portion of the elastic film, and positioning the partition radially by press fitting or inserting an upper cylindrical portion thereof into the bore are employed, whereby the manufacturing cost is reduced.
