A damper assembly comprises a monotube damper and a twintube damper in a telescopic configuration. A first piston is connected to a rod and is slidably disposed within a first tube. A second tube and a third tube are each disposed coaxially around the monotube damper, with the third tube disposed within the second tube and defining an annular chamber therebetween. A second piston is connected to an axial end of the first tube dividing an interior of the third tube into an upper chamber and a lower chamber. The second piston defines a twintube passage providing fluid communication therethrough. A base member defines a base passage providing fluid communication between the lower chamber and the annular chamber. A seal selectively blocks fluid flow through the twintube passage or the base passage and based on an axial position of the first tube relative to the second tube.

A shock absorber assembly includes a pressure tube having an upper end and a lower end and defining an interior, a rod guide disposed adjacent the upper end, a first compression valve assembly adjacent the lower end, a rod operatively coupled to the pressure tube having a first end and a second end, an extender coupled to the second end of the rod, a piston assembly coupled to the extender between the rod guide and the first compression valve assembly with the piston assembly disposed within the interior and slideably coupled to the pressure tube, with the piston assembly dividing the interior into an upper and a lower working chamber, a second compression valve assembly coupled to the extender between the piston assembly and the first compression valve assembly, and a cup disposed within the lower working chamber and defining a bore shaped to receive the second compression valve assembly.

A device for the height adjustment of a road vehicle interposed between a frame and a suspension of the road vehicle so as to allow the vehicle to shift from a road configuration to a race configuration and vice versa. The device comprises a base body provided with a first end, which can mechanically be connected to the frame of the road vehicle; a first mass, which can be connected to the base body so as to be movable along a sliding axis; a second mass, which is connected to the first mass so as to be movable along the sliding axis as well and is configured to be able to be connected to a suspension of the road vehicle and to change the stroke of the suspension depending on the position of the second movable mass.

A suspension device includes a pair of suspensions each containing at least one of a damping mechanism and a suspension spring. A tubular body-side member is on a vehicle body side. A tubular wheel-side member is on a vehicle wheel side and coupled to the body-side member, and moves relative to the body-side member in an axial direction. A hollow cylindrical cylinder is inside of the body-side member and the wheel-side member and includes a weak portion in the axial direction on an outer side. A rod member is inside of the body-side member and the wheel-side member and moves relatively in the axial direction in accordance with movement of the body-side member and the wheel-side member. A first defining member secured to an end portion of the rod member and in contact with the cylinder movably in the axial direction of the cylinder defines space in the cylinder.

A shock absorber includes a hollow cylinder body extending in an up-down direction, a rod pipe located on an axis of the cylinder body, provided to be relatively movable in an axial direction of the cylinder body with respect to the cylinder body, and provided in a form of receiving a force in the axial direction, a rod-shaped support body extending inside the rod pipe with an upper end fixed, a stroke sensor including a coil and a conductor provided to be able to detect relative displacement of the rod pipe with respect to the support body, and a hollow intermediate member provided between the inner peripheral surface of the rod pipe and the support body to allow movement in the axial direction.

A shock absorber includes a first end configured to be mechanically fastened to a first component, a second end configured to be mechanically fastened to a second component, a main body, a main shaft, and a primary piston. The primary piston configured to move within the main body and further configured to provide a first damping force by movement of a fluid through the primary piston while the main shaft moves a first distance. The shock absorber also includes a deformable solid material arranged in the main body. The primary piston configured to further move within the main body and further configured to provide a second damping force by deforming the deformable solid material after the main shaft moves the first distance.

A hydraulic damper for a vehicle including a main tube. A first piston assembly is slideably disposed in the main tube and axially divides the main tube into a rebound chamber and a primary compression chamber. A hydraulic compression stop assembly is disposed in the primary compression chamber and includes a narrowed section extending between an open end and a closed end. A second piston assembly is slideably disposed in the narrowed section and is coupled with the first piston assembly. The second piston assembly has a piston tube that extends between an opened end and a shut end. A displaceable partition is slideably disposed in the piston tube. A first auxiliary compression chamber is defined between the partition and the closed end of the narrowed section. A second auxiliary compression chamber is defined between the partition and the shut end of the piston tube.

A shock absorbing and height adjusting structure includes an inner tube, a lower piston assembly and an upper piston assembly. The inner tube includes an upper end, a lower end opposite to the upper end, and an inner space for accommodating a gas. The lower piston assembly includes a lower piston movably inserted into the inner tube, and a lower passage disposed at the lower piston. The upper piston assembly includes an upper piston movably inserted into the inner tube. When the lower passage is opened, the lower piston is moved relative to the lower end, and when the upper piston is forced, the upper piston has movement relative to the upper end toward the lower end to compress the gas.
