Title: Axial vibration damper for floating bearings

Abstract: A floating bearing having a stationary member and an axially translating member including a pair of O-rings which in combination with surfaces of the movable member and the stationary member define a contained space which is further subdivided by an extension of a surface of either the translating member or the stationary member to form two chambers substantially enclosed but connected through a restricted space formed by the extremity of the extension and a proximate opposing surface of the other member. The chambers are substantially filled with a viscous fluid which provides damping of axial displacements of said movable member relative to said stationary member produced in vibratory environments.
