Vibration damper for damping vibrations in a surface (20) of an object (21). The damper consists of an oscillating body (1) which is movably connected to the surface such that it is brought to oscillate so that the oscillating body transmits forces to the object which are principally oppositely directed to the forces which, through vibration, act on the object. The vibration damper displays a locating part (19) made from a shaped permanent material and intended to be fixedly attached to said surface (20) of the object (21). The locating part displays one or several inwardly-directed vibration-transmitting support walls (26-29). The oscillating body (1) is at least partially enclosed in a damping body (10) made from an elastic material, and the damping body is held in the locating part through cooperation with the inwardly directed walls (26-29).
A vibration damper assembly for attachment to a surface of an object to dampen vibrations in said surface comprising locating means forming a casing with an opening and an internal cavity defined by a plurality of inwardly defacing vibration-transmitting support walls whereby when said locating means is attached to said surface, said cavity is enclosed within said plurality of inwardly facing support walls and said surface, said locating means comprising a rigid material, an oscillating body moveably mounted within said cavity, and a damping element comprising a unitary structure and having an elastic material and at least partially enclosing said oscillating body, said damping element including spacing means projecting from said damping element towards corner regions of said cavity formed by said inwardly facing support walls thereby forming interstices between said damping element and said inwardly facing support walls, said spacing means comprising said elastic material.
A vibration damper assembly for attachment to a surface of an object to dampen vibrations in said surface comprising locating means forming a casing with an opening and an internal cavity defined by a plurality of inwardly facing vibration-transmitting support walls whereby when said locating means is attached to said surface, said cavity is enclosed within said plurality of inwardly facing support walls and said surface, said locating means comprising a rigid material, an oscillating body moveably mounted within said cavity, and a plurality of damping elements comprising an elastic material, said plurality of damping elements at least partially enclosing said oscillating body and not being partially enclosed within said oscillating body, said plurality of damping elements including spacing means projecting from said plurality of at damping elements towards corner regions of said cavity formed by said inwardly facing support walls thereby forming interstices between said damping elements and said inwardly facing support walls, said spacing means comprising said elastic material.
A vibration damper assembly for attachment to a surface of an object to dampen vibrations in said surface comprising locating means forming a casing with an opening and an internal cavity defined by a plurality of inwardly facing vibration-transmitting support walls whereby when said locating means is attached to said surface, said cavity is enclosed within said plurality of inwardly facing support walls and said surface, said locating means comprising a rigid material, an oscillating body movably mounted within said cavity, and at least one damping element comprising an elastic material entirely enclosing said oscillating body, said at least one damping element including spacing means projecting from said at least one damping element towards corner regions of said cavity formed by said inwardly facing support walls thereby forming interstices between said damping element and said inwardly facing support walls, said spacing means comprising said elastic material.
