Abstract: When a damping force adjustable shock absorber operates in a soft mode, a piston is performing a compression stroke, and a piston speed falls within an ultra low speed range, communication between an upper cylinder chamber and a reservoir is interrupted by an ultra low speed valve provided in a pilot passage. The interruption of communication enables expansion of an oil liquid in the upper cylinder chamber when the piston is performing the compression stroke and the piston speed falls within the ultra low speed range. A differential pressure is generated between an upper cylinder chamber side and a lower cylinder chamber side of a compression-side ultra low speed valve. As a result, when the piston speed falls within the ultra low speed range, the compression-side ultra low speed valve is opened, and a damping force having a valve characteristic achieved by the ultra low speed valve can be generated.

Abstract: Rotational translation of an inertial mass rotor is used for providing damping of low frequency noise and vibration. An axial component is mounted so as to translate axial movement of an inertial linearly-displaceable member to rotational movement of an inertial mass rotor. The translation to rotational movement of the inertial mass rotor provides inertial amplification in the form of translational-rotational coupling. This enables the construction of a compact assembly, which allows light ultra-low frequency resonances to be concentrated, and which absorbs such low frequency noise energy.

Abstract: A damper for use with an automotive coil over shock absorber. An outer damping sleeve is retained over the exterior surface of an inner body and includes a plurality of bypass ports to alternately align and unalign with bypass ports of the inner body to regulate a bypass flow of damping oil between an interior volume and an outer passage, thereby allowing variable damping control of the damper. The outer damping sleeve is connected to an internal floating piston (IFP) which rides inside the inner body. A control spring is retained for applying a force to the IFP to limit the free movement of the IFP and thereby control a damping force of the damper during the damping event. Increased pressure in the hydraulic damping oil causes the IFP to move, causing the bypass ports to open and close depending on the forces subject to the damper.
