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.
