A damping force variable shock absorber of the present disclosure is disclosed. The damping force variable shock absorber includes a cylinder having an inner tube and an outer tube filled with a fluid, a housing coupled to a lower end of a piston rod located inside of the inner tube and forming a connection passage therein, a magnet member provided inside the housing, a plunger moving by magnetic force of the magnet member, a first piston valve coupled to the outside of the housing to divide a compression chamber from a rebound chamber, and a second piston valve provided in the housing, wherein the connection passage is provided such that at least a part of the fluid flowing toward the first piston valve is bypassed to the second piston valve side by the opening and closing of the plunger.

The present disclosure relates to an adjustable bleed valve assembly for a shock absorber. The bleed valve assembly includes: a first adjustable bleed valve, and a second adjustable bleed valve arranged in series with the first adjustable bleed valve, wherein the first adjustable bleed valve and the second adjustable bleed valve are each pressure independently adjustable between a first open state and a second open state, wherein each adjustable bleed valve is adapted to throttle a damping fluid in the piston rod more in the second open state than in the first open state, wherein the first adjustable bleed valve and the second adjustable bleed valve are each adjustable between the first open state and the second open state independently from one another. An adjustment device and a method for adjusting the bleed valve assembly is also provided.

A shock absorber assembly including a first sheath slidingly housing inside it a first piston which is filled with hydraulic fluid, the first piston having a first stem extending from the first sheath and a first head contained inside the first sheath, a second sheath slidingly housing inside it a second piston which is filled with hydraulic fluid, the second piston having a second stem extending from the second sheath and a second head contained inside the second sheath. The first and second sheaths are fluidly connected to each other by means of at least one upper duct and a first interconnection duct passing through a control body. The control body houses at least one damping valve including a damping plate having holes suitable to allow a calibrated passage of the hydraulic fluid channelled by the first and second sheaths towards the control body; the control body houses a control valve connected to actuator means to be movable, in a regulation stroke, from an unlocked position, in which it does not interfere with the upper duct to a locked position, wherein the upper duct is occluded.

A method and apparatus for a damper. The damper comprises a fluid chamber having a piston dividing the chamber into a compression and rebound sides, a reservoir in fluid communication with the compression side of the chamber, and an isolator disposed between the compression side and the reservoir, whereby the isolator obstructs fluid flow between the compression side and the reservoir. In one embodiment, a bypass provides a fluid path between the compression side and the isolator.
