Abstract
In an air or gas spring having a metal cylinder with a rigid gas-tight closure at one end and a flexible convoluted diaphragm seal and piston at the other end, the piston has an inner floating member restrained vertically by hardened roller balls that ride in a hardened ball race and horizontally by elastomer spring material.
Claims4
In a vibration isolation system having means for providing a high degree of vibration isolation along an axial direction greater than along a direction orthogonal to said axial direction the improvement comprising,
- a floating member means for significantly increasing isolation from vibration along said orthogonal direction,
- means for supporting said floating member means with high stiffness along said axial direction many times greater than the stiffness provided by said system along said axial direction,
- and means for restraining movement of said floating member means along said orthogonal direction with very low stiffness of the order of that provided by said system along said axial direction,
- said means for supporting comprising thrust bearings having hardened balls between flat surfaces of hardened races which flat surfaces are in planes orthogonal to said axial direction.
