摘要： A damper assembly comprises a housing disposed on a center axis and defining a fluid chamber for containing a working fluid. A piston is slidably disposed in the fluid chamber dividing the fluid chamber into a compression chamber and a rebound chamber. A piston rod attaches to the piston for moving the piston in the housing. The piston includes a first portion and a second portion defining a first perforation. An outer sleeve has an exterior surface and an interior surface and extends between the first portion and the second portion covering the first perforation. The piston includes a first entry valve and a second entry valve located in the piston and coupled to the piston for limiting the working fluid from flowing into the piston with the first entry valve being disposed adjacent the first portion and the second entry valve being disposed adjacent the second portion.

摘要： A hydraulic damper includes a piston rod attached to a slidable piston assembly having a hollow housing with first and second valve assemblies disposed therein and each including a valve body and rebound and compression discs for regulating flow of a working fluid through the piston assembly. The first valve assembly is disposed about a sleeve with a valve nut securing them within the housing. The second valve assembly is threadedly secured in the housing, with a pin holding it together. The housing including a coil and an armature, axially slidable through a plunger guide with a spring biasing the armature to a first position with fluid allowed to flow through the sleeve to bypass the first valve. The armature slides to a second position with fluid not bypassing the first valve in response to the coil being energized by an electrical cable which extends through the piston rod.

摘要： A piston assembly for a damper includes a main piston disposed on a center axis. A piston rod is attached to the main piston. A regulator extends between the piston rod and the main piston defining a compartment. The regulator has at least one first aperture and at least one second aperture. A restrictor divides the compartment into a first and second portion. An actuator having a core is disposed in the first portion movable between an opened and a closed position. The restrictor includes a sleeve disposed in the compartment and attached to the regulator. The sleeve defines a hole in fluid communication with the first and second portions and flares outwardly in the first portion toward the regulator to define a slanted edge extending at an oblique angle relative to the center axis to allow the working fluid to flow smoothly thereby limiting noises generated.

摘要： A twin tube damper assembly includes a main tube defining a fluid chamber. An external tube extends about the main tube defining a compensation chamber therebetween. A piston, slidably disposed in the fluid chamber, divides the fluid chamber into a compression chamber and a rebound chamber. A rod guide is disposed in the rebound chamber, attached to the main tube and the external tube, defining at least one channel in fluid communication with the rebound and compensation chambers. A piston rod extends through the rod guide and is attached to the piston. A pressure rate sensitive system, disposed in the rebound chamber, is attached to the rod guide in fluid communication with the at least one channel, the rebound chamber, and the compensation chamber for regulating the working fluid flow through the rod guide between the rebound and compensation chambers during compression and rebound strokes.

摘要： A hydraulic damper (3) includes a tube (4), a piston assembly (5) disposed slidably inside the tube (4), and an additional valve assembly (13). A compression chamber (9) is defined between the piston assembly (5) and the additional valve assembly (13). An additional compensation chamber (14) is defined between the additional valve assembly (13) and one side of a slideable partition (10). A gas chamber (11) is defined at the other side of the slidable partition (10). The damper includes an additional chamber assembly (15) to retain all the advantages of a twin-tube damper while providing the single construction offered by a mono-tube damper. One end of the additional chamber assembly (15) is attached to the slidable piston chamber (5) or to said piston rod (6) at the compression side thereof and the other end of said additional chamber assembly (15) is terminated with the additional valve assembly (13).
