Title:
MAGNETICALLY DYNAMIC DAMPING ASSEMBLY
Document Type and Number:
Japanese Patent JP2019049355
Kind Code:
A
Abstract:
To provide an assembly for magnetically dynamic damping which is useful for isolating vibrational forces.SOLUTION: An assembly includes a housing wall 22 bounding a main chamber 28 therein. The assembly further includes a fixed magnetic source 70 disposed in the main chamber 28. A diaphragm 62 made of elastic material is disposed in the assembly and impermeably divides the main chamber 28 into sub-chambers 32. The diaphragm 62 includes a magnetically actuated element 72 located adjacent to the fixed magnetic source 70. A source of electrical current energizes the magnetically actuated element 72, the fixed magnetic source 70, or both and either repels or pulls the magnetically actuated element 72 with respect to the fixed magnetic source 70. A magnetic guide 76 surrounds the fixed magnetic source 70 and defines a gap exposing the fixed magnetic source 70 to the magnetically actuated element 72. The magnetic guide 76 routes the magnetic field towards the gap and prevents outward magnetic interference to the rest of the assembly.SELECTED DRAWING: Figure 1
