Lubricant of solid or liquid consistency, exhibiting low coefficient of friction
First Claim
1. A lubricant of solid consistency, exhibiting a low coefficient of friction, ranging from 0.044 to 0.067, with a liquid base and thickeners as solids, containing a mixture of three out of four metal soaps namely lithium-stearate, or alternately lithium-hydroxystearate, in the amount of from 5% to 10% by weight, calcium-stearate, or alternately calcium-hydroxystearate, in the amount of from 4% to 14% by weight, magnesium-stearate in the amount of from 3% to 9% by weight, or aluminum-stearate in the amount of from 3% to 9% by weight, and at the same time containing polytetrafluoroethylene in the amount from 4% to 8% by weight, and aforesaid metal soaps make up from 51% to 80% of the weight of a lubricating composition, while the liquid base ranges respectively from 49% to 20% by weight.

Abstract
The invention relates to a lubricant in the form of grease or thick lubricating gel or transmission oil, as well as motor or universal oils with a myriad of applications. As a result of its contents presented in the patent application is characteristic of low coefficient of friction ranging from 0.055 to 0.062. As the main component, the contents of the discussed lubricant includes three or four stearates of metals or hydroxistearates of metals, which interact and cause a noticeable reduction of friction drag on the lubricated surfaces. Additionally, these substances may include a number of other solid or liquid elements, which maintain low friction drags and, furthermore, improve the lubricant through increasing its load capacity, antirust characteristics, shear strength, etc. The lubricant made according to the invention underwent comparative tests against other greases and greasing oils, the accounts of which are included in the application as diagrams, descriptions of research tests and examples of the contents of the lubricant products.
