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 damper assembly includes a housing having a tubular shape defining a main chamber extending along a center axis. A piston is movable along the center axis and divides the main chamber into a compression chamber and a rebound chamber. The piston includes a piston body defining a frequency-adaptive orifice (FAO) passage providing fluid communication between the compression chamber and the rebound chamber. The piston includes an FAO valve assembly having an FAO cover member configured to block fluid flow therethrough in response to application of a low-frequency excitation, and allowing fluid flow through the FAO passage in response to application of a high-frequency excitation. The FAO valve assembly also includes a tappet configured to translate relative to the piston body to bias the FAO cover member to selectively cover the FAO passage in response to the application of the low-frequency excitation.

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.
