Definitions

• the present report describes a new fluid to be used in shock absorber of any nature and shock with biodegradable hydraulic fluid, in which the fluid described here will replace with great advantages the currently used mineral-based hydraulic fluid, and their variations, in today's shock absorber, that have no biodegradable properties and also low thermal stability, being that this new fluid improves functional development and increase in durability among other advantages.
• This Biodegradable Hydraulic Fluid for Shock absorber can have a synthetic base of the Group V or Glycol group, in solution or not, presenting high thermal stability a low viscosity variation, beside having a biodegradable characteristic.
• the viscosity and density must be compatible with the application of hydraulic fluid for shock absorber, enabling fractions of specific additives, such as anti-foam, anti-freeze and anti-effervescent among others.
• shock absorber consist of a usually cylindrical tube denominated pressure tube, in which a sliding piston is fitted in its interior with a triggering Rod through axial displacement, where the piston is responsible for the division of the tube into two chambers, being an extension and a compression chamber.
• the absorption force offered by the shock absorber is given through the passage control of hydraulic fluid between the extension and compression chambers, this control can by pre-defined through the combination of components that constitute the piston and still, when available, through a base valve in the pressure tube or a variable control valve of flow or pressure, being activated mechanically or electrically.
• shock absorbers are filled with a hydraulic fluid with physical and chemical characteristics determined by technical guidelines.
• Such hydraulic fluid generally fills both pressure chambers, in some cases having the need to add an external reservoir chamber, or still, depending on the model and the application, the addition of a chamber attached externally to the pressure tube, thus consisting, in the bitubular shock absorber, in which the oil volume the fills the reservoir chamber be capable to supply the difference in volume between the extension and compression chambers in function of the variation of material volume in the rod of the shock absorber, through axial displacement.
• the tritube shock absorber are constituted presenting the same function characteristics for the different application is destined to perform.
• compositions for the use in shock absorber possess the characteristics of a biodegradable and high thermal stability fluid at the same time, besides increasing performance and the life span of the shock absorber, according to the object of the present patent.
