A variable shock absorbing compressional mounting apparatus. The apparatus includes a housing assembly having first and second housing portions, with the second housing portion being operable to move slidably partially inwardly and outwardly relative to the first housing portion, and a cylindrical, elongated elastomer member having a cylindrical, serpentine-shaped spring therein disposed coaxially within said housing assembly. The elongated elastomer member and elongated serpentine-shaped spring operate cooperatively to provide damping characteristics which vary with the compressional and tensional forces exerted on the elastomer member. When the apparatus is secured to two structures moving towards and away from each other in an oscillatory fashion with varying force, the apparatus operates to dampen the oscillatory motions of the structures in accordance with a first damping characteristic until a predetermined force is reached. At this point the elastomer member/serpentine spring combination provides a second damping characteristic which allows for less damping of the oscillating movements of the structures to which the apparatus is secured. The apparatus is particularly well-suited for such applications as mounting motors, engines and other like-vibration inducing structures to frame-like structures. The apparatus provides the further advantage of significantly attenuating vibrational noise normally otherwise transmitted to the frame-like member to which it is attached.
