Abstract

Amortisseur pour véhicule. L'amortisseur selon la présente invention comporte un tube 12 rempli d'un fluide hydraulique et un piston 16 divisant le tube 12, en une chambre supérieure et une chambre inférieure, le piston étant fixé à l'une des extrémités d'une tige 26 de piston de manière à être déplacé jusqu'à une position basse, quand l'amortisseur subit une compression, et jusqu'à une position haute quand il subit une extension. Un compartiment 56 est formé à l'intérieur dudit piston et une multiplicité de premiers passages 64 est formée pour faire communiquer la chambre supérieure avec le compartiment 56, lesdits premiers passages s'etendant en hélice pour que le fluide se trouvant dans ladite chambre puisse se décharger dans le compartiment à travers ce dernier sous la forme d'un vortex de telle sorte que la pression du fluide diminue et que le choc ayant engendré le déplacement du piston est absorbé. Des seconds passages 70 sont en outre formés dans le piston pour faire communiquer le compartiment 56 avec la chambre inférieure.Shock absorber for vehicle. The shock absorber according to the present invention comprises a tube 12 filled with hydraulic fluid and a piston 16 dividing the tube 12 into an upper chamber and a lower chamber, the piston being fixed to one end of a rod 26. piston so as to be moved to a low position when the shock absorber is compressed, and to a high position when it is extended. A compartment 56 is formed within said piston and a multiplicity of first passages 64 are formed to communicate the upper chamber with the compartment 56, said first passages extending helically so that the fluid in said chamber can flow. discharge into the compartment through the latter in the form of a vortex so that the pressure of the fluid decreases and the shock which has generated the displacement of the piston is absorbed. Second passages 70 are further formed in the piston to communicate the compartment 56 with the lower chamber.
