摘要： A suspension damper includes a housing bounding a main chamber. A piston rod is slideably disposed within the main chamber of the housing. A main piston is mounted on the first end of the piston rod within the main chamber of the housing so as to slideably engage against the housing in sealed engagement, the main piston having a first side and an opposing second side with a compression port extending therebetween. A secondary piston is also disposed within the main chamber and has a compression port extending therethrough. A control valve assembly is disposed within the main chamber and bounds a sealed valve compartment. The control valve assembly is movable between a first position wherein the valve compartment is compressed to a first volume and a second position wherein the valve compartment is expanded to an enlarged second volume, the control valve assembly being movable under pressure so as to provide variable compression damping properties.

摘要： A suspension damper (10) includes a housing bounding a main chamber. A piston rod (34) is slideably disposed within the main chamber of the housing. A main piston (38) is mounted on the first end of the piston rod within the main chamber of the housing so as to slideably engage against the housing in sealed engagement, the main piston having a first side and an opposing second side with a compression port extending therebetween. A control valve assembly is disposed within the main chamber and bounds a sealed valve compartment. The control valve assembly (100) is movable between a first position wherein the valve compartment is compressed to a first volume and a second position wherein the valve compartment is expanded to an enlarged second volume, the control valve assembly being movable under pressure so as to provide variable compression damping properties.

摘要： A shock absorber is disclosed herein with a frequency sensitive damping force that includes a cylinder containing a damping medium, a piston rod which is axially movable in the cylinder, and a piston assembly arranged for axial movement in the damping medium. The piston assembly is connected to the piston rod and divides the cylinder in a working space on each side of the piston. The piston assembly includes a flow path fluidly coupled to a frequency sensitive element movable relative to the piston assembly.

摘要： A damper includes a housing bounding a chamber. A barrier is movably disposed within the chamber so as to divide at least a portion of the chamber into a pressure compartment and a control compartment each having a volume, the volume of the pressure compartment and the control compartment each being adjustable based on movement of the barrier. A first compressible gas is disposed within the pressure compartment while a first hydraulic fluid is disposed within the control compartment A piston shaft has a first end slidably disposed within the control compartment. A temperature compensator disposed within the chamber automatically adjusts the combined volume of the pressure compartment and the control compartment based on the temperature of the first hydraulic fluid within the control compartment so as to regulate the pressure within the control compartment.
