摘要： A twin-tube shock damper has a hollow piston rod (5) which extends towards the top of the working cylinder (1), a baseplate (8) which closes off the working cylinder and a disc (7) which is arranged inside the working cylinder between the piston (4) and the baseplate and has one or more passages (16) and a non-return valve (17) which allows upward flow through the passages, a central tube (10), a connection (11) between the hollow piston rod and the space above the piston, a damping valve (21) which operates in one direction of flow and servo-control means having an excitation chamber (18) and an excitable coil (30). A control valve in the form of a hollow piston (25) movable in a control valve cylinder (22) provided with orifices (24) and a hollow shaft (27) guided in a valve shaft guide (26) provided with orifices (28) are located in the excitation chamber. Both the control valve cylinder and the control valve are pushed by spring means (23, 29) in the direction of the damping valve body (17).

摘要： A twin-pipe shock absorber comprises a working cylinder (1), a piston (4) which is movable in the cylinder and has a passage and upstream valve (13, 14, 15). Round the working cylinder an external pipe (2) is fitted and an oil tank (3) is present between the working cylinder and the external pipe. The working cylinder is shut off by a disc (7) having a passage (16) and an upstream valve (17) positioned near said passage. Further the absorber is provided with a damper valve. To produce a shock absorber in which the shock absorption can be adapted very rapidly to the frequency of movement of the unsprung wheel guide part a central pipe (10) extends through the piston (4) and with its bottom end projects through said disc (7). The damper valve is disposed at the bottom end of said central pipe (10), and regulation means are present to regulate the damping exerted by the damper valve depending at least on the frequency at which the working cylinder vibrates.

摘要： A one-pipe shock absorber which is adjustable both in the pull and in the push direction comprises a first damping disc (21), provided with passages (22) for damping the outwards piston movement, a second damping disc (20), provided with passages (22), for damping the inwards piston movement, and a seating ring (36), which extends between the two damping discs (20, 21), the damping discs (21, 20) being movably fitted in the piston with a fixed axial spacing relative to one another and the spacing between the damping discs being greater than the height of the seating ring (26), so that when the one damping disc engages on the seating ring the other damping disc is clear of the seating ring. Adjustment means for damping comprise a slide (23a, 23b) which is associated with each disc, which can be operated remotely and which can close, respectively, a larger or smaller number of passages (22) in the discs (20, 21).

摘要： A twin-pipe shock absorber comprises a disc (7) which is fitted between the piston (4) and the bottom plate (6) inside the working cylinder and which is provided with one or more bores (17), a non-return upflow valve (19) for regulation of the upgoing flow through the bores (17) in the disc (7), a central pipe (8) extending through the piston (4) in the hollow piston rod (5) and through the disc (7), a regulated first damper valve (34) fitted at the bottom end of the working cylinder, and a regulating mechanism fitted below the first damper valve (34) in order to regulate the flow resistance caused by the above-mentioned first damper valve. In order to let the shock absorber function well at very high piston speeds without limitations regarding the dimension of piston and piston rod, the first damper valve (34) is intended purely for damping of the inward stroke of the piston rod (5), whereas a regulated second damper valve (12, 12a) is fitted in the piston (4) for the purpose of damping the outward stroke of the piston rod (5), and the regulating pressure for the second damper valve (12, 12a) is governed by means of the central pipe (8) of low cross-sectional area by the regulating mechanism.

摘要： A continuously variable single-tube shock absorber operating according to the skyhook principle and having bidirectional control valves comprises a working cylinder (1), a piston (3) with piston rod (2) which is movable therein, openings (6, 7) cut out in the piston, spring-loaded shock absorber valves (8, 9), fitted on either side of the piston, in order to shut off the openings until a certain fluid pressure has been reached, exciting chambers (12, 13) fitted on either side of the piston and each bounded by a stationary disc (10, 11), a piston skirt (14, 15) which can be slid around such a disc, and a spring-loaded shock absorber valve. The exciting chambers are in communication with a bore (23) in which the pressure is controlled by a control mechanism. Bores (20, 21) through which fluid can flow into the exciting chambers are provided in the stationary discs. The control mechanism can consist of a movable mass which is fitted in a spring-loaded manner and controls the passage of fluid to a bore which is in communication with the exciting chambers, or it can consist of valves to be adjusted by a coil (37).

摘要： Amortisseur à deux tubes comportant un disque (7) monté entre le piston (4) et la plaque de fond (6) à l'intérieur du cylindre de travail, et doté d'un ou plusieurs perçages (17), un clapet antiretour (19) régulant l'écoulement ascendant à travers les perçages (17) ménagés dans le disque (7), un tube central (8) traversant le piston (4) dans la tige creuse (5) et traversant également ledit disque (7), une première soupape d'amortissement régulée (34) montée au fond du cylindre de travail, ainsi qu'un mécanisme régulateur monté sous ladite première soupape (34) pour réguler la résistance hydraulique engendrée par cette dernière. Afin de permettre à l'amortisseur de bien fonctionner à des vitesses de piston élevées et sans imposer de limites aux dimensions du piston et de la tige de piston, la première soupape (34) sert uniquement à amortir la course de rentrée de la tige de piston (5), tandis qu'une seconde soupape d'amortissement régulée (12, 12a) est montée dans le piston (4) pour amortir la course de sortie de la tige de piston (5), et la pression de régulation de ladite seconde soupape (12, 12a) est commandée par le mécanisme régulateur au moyen du tube central (8) présentant en section une superficie réduite.

摘要： L'amortissuer à tubes jumelés décrit comprend un cylindre de travail (1) et un piston (4) qui est mobile dans le cylindre et qui comporte un passage et une soupape amont (13, 14, 15). Un tube extérieur (2) est monté autour du cylindre de travail et un réservoir d'huile (3) se trouve entre le cylindre de travail et le tube extérieur. Le cylindre de travail est obturé au moyen d'un disque (7) comportant un passage (16) et une soupape amont (17) disposée à proximité dudit passage. Ledit amortisseur est en outre pourvu d'une soupape amortisseuse. Pour obtenir un amortisseur de chocs dans lequel l'amortissement peut être adapté très rapidement en fonction de la fréquence des mouvement de l'élément de guidage des roues non suspendues, on fait en sorte qu'un tube central (10) s'étende à travers le piston (4) et que l'extrémité inférieure de ce tube forme saillie à travers le disque (7). La soupape amortisseuse est disposée au niveau de l'extrémité inférieure du tube central (10) et des organes de régulation sont prévus pour réguler l'amortissement exercé par la soupape amortisseuse en fonction au moins de la fréquence à laquelle se produisent les vibrations du cylindre de travail.
