摘要： A hydraulic damping device comprising a housing (2) having a cylinder space (3) defined by a cylindrical inner wall (4) of the housing, a piston (7) arranged movably in the cylinder space (3), a piston rod (8) arranged to the piston (7) and extending to the outside of the housing (2), means for moving the piston (7) from a first position, in which the piston rod (8) is in a retracted position, to the second position, in which the piston rod (8) is in an extended position, and a fluid tank (20) operationally connected via fluid channel (19) to the cylinder space (3). The damping device (1) is configured to damp a movement of the piston (7) and the piston rod (8) from the extended position of the piston rod (8) to the retracted position of the piston rod (8) achieved by an external force directed to the piston rod (8), wherein a fluid flow is achieved by pressing the fluid with the piston (7) from the cylinder space (3) to the fluid tank (20) via the fluid channel (19), and the device comprises means for returning the piston (7) to the extended position of the piston rod (8) when the external force is not directed to the piston rod. The invention relates also to a hinge arrangement and a machine.

摘要： A vehicle suspension damper (300; 400; 500) comprising:
a cylinder (302; 402; 510) containing damping fluid and a piston assembly comprising a piston (366; 466; 540), a piston rod (305; 405; 520), a first fluid path (451) and a second fluid path (452) through the piston assembly for permitting damping fluid to pass from a first side to a second side of the piston (366; 466; 540) during a compression stroke of the vehicle suspension damper; and
a valve member (201; 301; 560) for resisting fluid flow through the second fluid path (452);
characterized in that
said valve member (201; 301; 560) provides a restriction to fluid flow through the second fluid path (452), the restriction being independent of the pressure of the damping fluid caused by compression of the vehicle suspension damper (300; 400; 500).

摘要： La présente invention se rapporte à un dispositif de suspension (100, 200) de véhicule formé par un amortisseur (10, 210) et un ressort hélicoïdal (20) montés en parallèle, l'amortisseur et le ressort étant coaxiaux, ledit amortisseur comportant au moins un corps (11a, 11b) délimitant au moins une cavité (12a, 12b) cylindrique dans laquelle coulisse un piston (13) solidaire d'une tige de piston (131), et un dispositif de décharge comprenant un conduit (14) traversant axialement ledit piston, un gicleur (15) à une extrémité dudit conduit et un pointeau (16, 216) pour limiter le débit à la sortie dudit gicleur. Des moyens élastiques agissent sur le pointeau pour maintenir le gicleur fermé en position statique, une force exercée par lesdits moyens élastiques étant déterminée pour que le pointeau s'ouvre quand un fluide traversant le conduit exerce une pression sur ledit pointeau, la course d'ouverture dudit pointeau étant fonction de la pression exercée par le fluide traversant le conduit.

摘要： A damper device includes a cylinder body and a piston body, and at least one of the cylinder body and the piston body is attached to an article subject to damping so that the damping is applied to a movement or a relative movement of the article subject to the damping. The damper device has a run-through hole formed in an inner recess part of the cylinder body facing the piston body, and a stopper-like body having a shaft part, which is inserted into the run-through hole. An entering length of the shaft part of the stopper-like body into the run-through hole changes by a change of pressure caused by a movement of the piston body.

摘要： A shock absorber includes a tube and a piston rod carrying a piston. The piston is configured for reciprocal movement within the tube. A floating piston, or other type of accumulator, is configured to move to accommodate fluid displaced due to successive portions of the piston rod entering the tube during compression of the shock absorber. The shock absorber includes a valve mechanism that utilizes the movement of the floating piston to move the valve between a first and second position, which preferably are open and closed positions.
