ABSTRACT:
A liquid filled vibration isolating mount has upper and lower metal fittings for fixing the vibration isolating mount to a supporting body and a supported body. A rubber vibration isolating body has a tubular shape defining a central cavity and has upper and lower ends defining an upper face and a bottom face which are respectively fixed to the upper and lower metal fittings. The upper metal fitting defines an aperture communicating with the central cavity and a partition member is connected to the upper metal fitting occluding the aperture. A diaphragm is attached to the upper metal fitting covering at least a portion of the partition member. The central cavity of the vibration isolating base body and the partition member define a first liquid chamber wherein the vibration isolating base body constitutes a portion of a chamber wall. The diaphragm and the partition member define a second liquid chamber. The second liquid chamber is partitioned from the first liquid chamber by the partition member and the partition member defines an orifice communicating the first liquid chamber with the second liquid chamber. A rubber elastic membrane is connected to the lower metal fitting and forms a portion of the chamber wall of the first liquid chamber. The rubber elastic membrane has an inversed cup shape projected from the bottom face of the vibration isolating base body into the first liquid chamber and the inversed cup shape forms an air chamber within itself.
