An apparatus for preventing the transmission of vibrations from one object to another including a first and second frame having a rod attached to one of the frames and the other being slideably mounted to the rod. An air bag or other force transmitting mechanism is attached to one end thereof to one of the frames and abuts the other of the frames. A source of fluid is provided for pushing the first and second frames apart when such fluid is allowed to flow into the force transmitting apparatus. A biasing structure is provided for causing the frames to move closer together when fluid is allowed to escape from the force transmitting apparatus and a valve structure is connected between the fluid supply and force transmitting apparatus for selectively controlling the flow of the fluid between the air bag, a source of pressurized fluid and atmosphere. A third frame, a second rod, a second force transmitting apparatus, biasing apparatus and valve and valve actuating mechanism are also provided for isolating transmissions of force in a similar fashion, but in a direction transverse to the direction of movement of the first and second frame referred to immediately above.
