The present disclosure relates to a shock absorber, in more detail, a damping force controlling shock absorber of which a damping force characteristic can be appropriately adjusted. A damping force controlling shock absorber according to the present disclosure includes: a cylinder formed in a double structure of an inside and an outside, having an internal space divided into a compression chamber and a rebound chamber by a piston valve, and having a reservoir chamber in an external space; a compression solenoid valve mounted on the cylinder; a rebound solenoid valve mounted on the cylinder; and a check valve disposed in the rebound solenoid valve, and opening and closing a channel connecting the reservoir chamber and the rebound chamber.

Disclosed is a continuous damping control shock absorber, which has a dual solenoid valve structure in which a rebound solenoid valve and a compression solenoid valve are provided, including a post port mounted on an outer side of a base shell and in which the rebound solenoid valve and the compression solenoid valve are installed to be spaced apart from each other by a predetermined distance, wherein the post port is provided with at least one communication hole to directly communicate the rebound solenoid valve and the compression solenoid valve.

A shock absorber having a shock absorber tube (10) is disclosed and has an external module tube (11) which is connected to the shock absorber tube (10) via a flange (12), wherein the flange (12) has one or more fluid ducts (13, 14) which fluidically couple the module tube (11) to the shock absorber tube (10). The flange (12) has at least one metallic support cage (15) which forms a retentive connection between the shock absorber tube (10) and the module tube (11), and the flange (12) has a plastics body (16) in which the fluid duct (13, 14) for the fluidic coupling of the module tube (11) to the shock absorber tube (10) is formed.

A shock absorber having a shock absorber tube (10) is disclosed and has an external module tube (11) which is arranged retentively on the outside of the shock absorber tube (10) by a flange (12), wherein the flange (12) has one or more fluid ducts (13, 14) which fluidically couple the module tube (11) to the shock absorber tube (10). The flange (12) has a plastics body (15) in which the fluid ducts (13, 14) are formed, and the flange (12) furthermore has metallic connecting elements (16, 17) which extend between the shock absorber tube (10) and the module tube (11) and by which the mechanically retentive connection between the shock absorber tube (10) and the module tube (11) is formed.

A baffle plate (41, partition member) is manufactured by being integrally formed of a single material including flexible or pliable NBR (nitrile rubber), and a projection (51) formed on an abutment surface (42B) of the baffle plate (41) is fitted into a recess (52) in a reduced-diameter portion (36) of an intermediate tube (20). Thus, when the intermediate tube (20) fitted with the baffle plate (41) is assembled into an outer tube, the sheet-shaped baffle plate (41) can be prevented from rotating about a connecting pipe (23), and it is possible to improve the productivity and assembleability of the shock absorber.

An electronic valve assembly for a vehicle suspension damper is described in which a first electronic valve is disposed along a fluid flow path extending between a compression region of a damping cylinder and a fluid reservoir chamber. The first electronic valve controls flow of fluid from the compression region into the fluid reservoir chamber. A second electronic valve is disposed along a fluid flow path extending between a rebound region of the damping cylinder and the compression region. The second electronic valve controls flow of fluid from the rebound region into the compression. The first electronic valve does not reside in the fluid flow path extending from the rebound region into the compression region, and the second electronic valve does not reside in the fluid flow path extending from the compression region into the fluid reservoir chamber.

A suspension controller includes a target current setting unit configured to set a target current value, a current limitation setting unit configured to set a current limitation value, a current detector configured to detect a current value of a first current supplied to a solenoid that is configured to control a damping force of a suspension, a duty ratio setting unit configured to set a duty ratio based on the target current value, based on the current limitation value, and based on the current value detected by the current detector; and a current outputting unit configured to supply the solenoid with a second current that corresponds to the duty ratio set by the duty ratio setting unit and to a power supply voltage. The current limitation setting unit is configured to change the current limitation value based on the duty ratio set by the duty ratio setting unit.

A damper includes a pressure tube extending about a longitudinal axis and defining an inner volume. The damper includes a piston attached to a piston rod and slidably disposed within the pressure tube. The piston divides the inner volume of the pressure tube into a first working chamber and a second working chamber. The damper includes a fluid connector having a first wall and a second wall, each elongated along the longitudinal axis and sealed to the pressure tube. The fluid connector has a third wall elongated along the longitudinal axis and extending from the first wall to the second wall. The pressure tube defines an opening at the first working chamber, and the third wall of the fluid connector defines an opening spaced from the opening of the pressure tube. The first wall, the second wall, and the third wall define a passage extending from the opening of the pressure tube to the opening of the third wall.

An adjustable vibration damper includes at least one adjustable damping valve, with a piston at a piston rod that divides a cylinder into a work chamber on the piston rod side and a work chamber on the side remote of the piston rod. The cylinder is at least partially enclosed by an intermediate tube that forms a fluid connection between one of the work chambers and the adjustable damping valve. A hydraulic apparatus is connected to the fluid connection of the one work chamber via a first line and to the other work chamber via a second line.
