摘要:
A damper assembly includes a piston and cylinder type damper with a piston (14) mounted for reciprocal movement in a cylinder (10) containing damping fluid. The piston (14) is acted on by a piston rod (11) which includes a reaction surface for engaging the piston. The cross-sectional area of the reaction surface is designed to be significantly greater than the cross-sectional area of the piston rod (11) in order to spread the load exerted on the piston (14). Also, the piston (14) is designed to engage the piston rod (11) at its inner end in a manner that provides lateral guidance for the inner end of the piston rod in its movement in the cylinder (10).

L'Invention est relative à un amortisseur de vibrations caractérisé en ce qu'il comporte : - un boîtier (10) délimitant une chambre annulaire (11) - un piston (1) présentant une couronne centrale (2) coulissant dans la chambre annulaire (11), laquelle a un contour externe de diamètre supérieur ou sensiblement égal au diamètre extérieur de la couronne centrale (2) de sorte que la chambre annulaire est séparée en un premier (11 1 ) et un deuxième (11 2 ) compartiments, - deux éléments d'assemblage disposés aux extrémités opposées du piston, un premier élément d'assemblage (6) étant solidaire du boîtier (10) et un deuxième élément d'assemblage (7) étant solidaire du piston (1). - au moins un dit compartiment (11 1 , 11 2 ) présentant au moins un coussin métallique en fil tricoté - un fluide d'amortissement remplissant la chambre annulaire (11), y compris les interstices antres les mailles du ou des coussins métalliques (21, 22).
摘要:
A fluid spring assembly (50). The spring assembly preferably includes a body (52) that slidably supports a piston (58) that is attached to a piston rod (64). The piston serves to define a fluid chamber within the body that is charged with a pressurized fluid medium. The piston is retained within the body by a rigid retainer member (90). A biasing member (84) is provided between the retaining member and the piston for resisting the force generated by the fluid medium within the fluid chamber.
摘要:
The invention concerns a damper with high dissipating power comprising a piston-rod assembly (12) sliding in a cylinder (1) defining on either side of the piston (13) a working chamber (18, 19) containing hydraulic fluid. The invention is characterised in that each working chamber (18, 19) communicates permanently with an associated chamber (20, 21) containing a heterogeneous energy absorbing-dissipating structure consisting of a porous capillary matrix (51, 61) and an associated liquid (52, 62) towards which the matrix is lyophobic. Further, each working chamber (18, 19) communicates with a common equalizing chamber (30) via an associated valve system (32, 33) including non-return means (40, 41) which automatically closes the chamber concerned during compression, and opens said chamber during expansion.

摘要:
A dashpot damper for acting between two objects subject to move toward and away from one another includes a housing (12) including an elongated cavity (66), a piston mounted within the housing cavity for reciprocating movement therealong and dividing the cavity into two variable-volume, hydraulic fluid chambers (67, 69), and a network of passages permitting hydraulic fluid to flow between the two variable-volume chambers as the housing and piston move relative to one another in response to relative movements between the two objects. The damper utilizes unitary flow control cartridge (16, 17) mounted within the housing and defining a passageway (186) through which hydraulic fluid is forced to flow when passing between the two variable-volume chambers (67, 69). The flow control cartridge (172) also restricting the flow of hydraulic fluid in one direction through the passageway (186) and for permitting substantially unrestricted flow of hydraulic fluid in the other direction through the passage. By controlling the flow of hydraulic fluid through the passageway (186) in said one direction, the damping effect of the damper is controlled. The flow control cartridge (16, 17) can be constructed so as to provide either an adjustable or fixed restriction to the hydraulic fluid flow in said one direction.
