Abstract:
1. A vibration isolating apparatus comprising: a first mounting member connected to one of a vibration generating portion and a vibration receiving portion; a second mounting member connected to the other of the vibration generating portion and the vibration receiving portion; an elastic body that is disposed between the first mounting member and the second mounting member and that is elastically deformable; a main liquid chamber having a partitioning wall, a portion of which is formed by the elastic body, the main liquid chamber being filled with liquid, and the content volume of the main liquid chamber being changed due to deformation of the elastic body; an auxiliary liquid chamber having a partitioning wall at least a portion of which is formed in a deformable manner, the auxiliary liquid chamber being filled with liquid; an orifice that connects the main liquid chamber and the auxiliary liquid chamber; a switching member that is disposed so as to be capable of moving reciprocally within a space including a portion of the orifice and that opens and closes the orifice due to reciprocating movement of the switching member; a non-return valve that is disposed between the main liquid chamber and the switching member and allows flowing of liquid from the main liquid chamber only towards the switching member; and an elastic member that urges the switching member to the side of the non-return valve.
