groove shape, etc.

 

Shows the initial claim application for an invention filed by me in to FIPS dashing nineties. Because of several well-known to all who had dealings with that office artificially contrived obstacles, offended and rejected all the patents. Application is naturally lowered into the archive, now of course order more, but to renew because of the paper under the title of protection shall not want.

 From himself said that the time to try the ring on three cars, and they have proven themselves excellent, fully confirming the characteristics specified in the formula. During the test, concluded that effective ulotneniya just takes a compression and an efficiently operating oil ring. Currently used labyrinth of two and sometimes more piston rings as well as the use of the overhead of locks and other beveled step is confusing.

 

 Misleading as well and the application package from the twisted steel rings with offset locks. The fact that these measures do not have significant advantages over classical ring with straight lock, because a leak occurs through the thermal gap at the junction of the piston ring grooves, where the gas pressure on the inner surface of the ring is the same as in nadporshnevoy cavity. Therefore, leakage is inevitable, and no labyrinth seal will not help because the gases have passed through the gaps of the upper rings, already does not fall into the cavity nadporshnevuyu

 

Ring my proposed design virtually eliminates blow-by through the thermal gap even at the maximum allowable wear of the ring and cylinder liner. Offered only one option of manufacturing a piston ring with those characteristics (Castle inverted Z - shaped cross section) in which the leading expert of the Patent Office under examination on the merits, by reason known only to him, stubbornly did not want to see the difference between direct lock step and clearly not able to explain their point of view. On that fact, I was offended.

Those wishing to take the invention to its - wide road! But this is not the best option, because there is another option (design) is much cheaper and more efficient (in order). Presented at the other pictures I have copies of all material correspondence with the Patent Office fully reveal the essence of the invention and intended to sell their legal form, as

transfer of know how of the person concerned

Sincerely Sergei!
