ABSTRACT:
A liquid filled vibration isolating mount has a rigid tubular fitting defining an interior fitting cavity, an upper opening and a lower opening. A vibration isolating base body formed of elastic material is fitted in the upper opening of the rigid tubular fitting. A diaphragm seals the lower opening of the rigid tubular fitting and a partition is disposed in the interior fitting cavity of the rigid tubular fitting between the vibration isolating base body and the diaphragm to divide the interior fitting cavity into a first liquid chamber and a second liquid chamber. The first liquid chamber has a first liquid chamber wall formed at least in part by the vibration isolating base body, the partition and the rigid tubular fitting. The second liquid chamber has a second liquid chamber wall formed at least in part by the diaphragm and the partition. The partition defines an orifice communicating the first and the second liquid chambers with each other. The rigid tubular fitting forms at least a portion of a side wall of the first liquid chamber wall and defines at least one opening in the side wall. An elastic membrane cup covers each of the at least one side wall opening and has a convex surface projecting into the first liquid chamber and a concave surface defining an air chamber separated from the first liquid chamber by the elastic membrane cup and extending into the interior fitting cavity. The air chamber may be sealed or open to the atmosphere.
