摘要： The invention relates to a shock absorber (1) comprising a damping cylinder (2) filled with a damping medium and divided into a first and a second damping chamber (C1, C2) by a main piston assembly made up of a first (4) and a second main piston (5). The main pistons, having continuous ducts (9, 10; 13, 14) which are delimited in a direction of flow by first and second flow limiters (11, 12; 15, 16), are mounted on a piston rod (3). The piston rod (3) has an axially extending and continuous cavity (7), through which damping medium is able to flow between a pressurized chamber (6a) of a pressurization reservoir (6) and the respective damping chamber (C1/C2). The damping medium flows via an interspace (8), delimited by the first and the second main piston (4, 5), in the main piston assembly, out into the respective damping chamber (C1/C2) via pressurization ducts (9, 10) delimited by return and compression flow limiters (11, 12). The invention is characterised in that the first and/or the second check valve (11, 12) is open in the initial part of the return or compression stroke (R2, R1), to enable a flow between the respective damping chamber (C1, C2) and the interspace (8) during the first part of the stroke (R2, R1). By enabling an initial flow between the damping chambers, desirable damping properties which, for example, result in a rapid rebound or spring back of the wheel are obtained.

摘要： A shock absorber has a main piston and a compression piston, connected by a compression piston housing. In stage 1, the shock absorber operates as a conventional monotube, with the damping force being generated only by the main piston. In stage 2, the compression piston travels into the compression housing, as the shock absorber still operates as a monotube damper. In stage 3, the compression piston is now significantly increasing its compression damping force by supplementing the main piston. The oil volume in the compression piston housing passes through the compression piston, causing an increase in compression damping force.

摘要： A hydraulic damper assembly comprises a housing extending between a first end and a second end. A main piston is slidably disposed in the fluid chamber dividing the fluid chamber into a first chamber and a second chamber. A piston rod extends along a center axis and attaches to the main piston. An additional piston is coupled to the piston rod and axially spaced from the main piston. The additional piston includes a main body defining a compression channel and a rebound channel that allow fluid to flow through the additional piston. A securing member secures the additional piston to the piston rod and defines an outer groove. A piston ring is located in the outer groove between the additional piston and the securing member. The piston ring is radially spaced from the securing member to allow the piston ring to be in engagement with the housing.

摘要： The hydraulic stop member comprises: a cup-shaped body mounted in a compression chamber of the shock-absorber. A piston is mounted at an end of a rod of the shock-absorber so as to slide in the cup-shaped body when the shock-absorber is close to an end-of-travel position of the compression stroke. The cup-shaped body includes a side wall and a bottom wall which define, along with the piston, a working chamber where a damping fluid of the shock-absorber is compressed by the piston. A bypass conduit connects a working chamber with the portion of the compression chamber placed above a seal ring. A pressure relief valve keeps the bypass conduit closed as long as the pressure in the working chamber remains below a given threshold value and to open the bypass conduit, thereby allowing the discharge of the damping fluid from the working chamber to the compression chamber through the bypass conduit, when the pressure in the working chamber exceeds the threshold value.

摘要： In a shock absorber of a vehicle, when a moving speed of a piston rod in relation to a cylinder tube is slow and first and second input forces are externally applied to the shock absorber, damping forces of pressure side and extension side first damping force generating devices are larger than that of pressure side and extension side second damping force generating devices. On the other hand, when the moving speed is fast, the damping forces of the pressure side and the extension side second damping force generating devices are larger than that of the pressure side and the extension side first damping force generating devices. A gas enclosure chamber filled with gas is connected to a first chamber through a free piston.
