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.

Apparatus for preventing the transmission of vibrations from one object to another comprising: a first frame; a second frame; a rod attached to one of said first frame and said second frame; bushing means for slideably receiving said rod, said bushing means being adapted to be attached to the other of said frames; fluid supply means for supplying a compressible, nonhydraulic fluid under pressure; force transmitting means attached at one end thereof to one of said frames for sealingly receiving said fluid under pressure; abutment means associated with said other frame for contacting the other end of said force transmitting means for causing said frames to be pushed apart when fluid under pressure is allowed to enter said force transmitting means; means for causing said frames to move closer together when fluid pressure is relieved in said transmitting means; valve means connected between said fluid supply means and said force transmitting means for selectively allowing the fluid to flow selectively from said fluid supply means to said force transmitting means in one position thereof, from said force transmitting means to atmosphere in a second position thereof or to allow no flow at all to or from said force transmitting means in a third position of said valve means; means operatively connected to said valve means for causing said valve means to be at said third position thereof when said frames are a predetermined distance apart, at said first position thereof when said frames are closer together than said predetermined distance and at said second position when said frames are farther apart than said predetermined distance; a third frame; a second rod operatively attached to one of said first and third frames, said second rod being disposed transversely with respect to the first said rod; second force transmitting means operatively attached at one end thereof to said frame at one end thereof and to said third frame at the other end thereof; second bushing means operatively attached to the one of said first and third frames which does not have a second rod attached thereto for slideably receiving said second rod; means for causing said first and third frames to move closer together when fluid pressure is relieved in said second force transmitting means; second valve means for selectively connecting said second force transmitting means to said fluid supply means in a first position thereof, from said second force transmitting means to atmosphere in a second position thereof or to allow no flow at all to or from said second force transmitting means in a third position thereof; and means connected to said second valve means for causing said second valve means to be at said third position thereof when said first and third frames are a predetermined distance apart, at said first position thereof when said first and third frames are closer together than said predetermined distance thereof and at said second position thereof when said first and third frames are farther apart than said predetermined distance thereof.
