Abstract
A pollution-free liquid balancing device comprises a sealing bag (1), a front cover (2), a rear cover (3) and liquid balancing matter (4), wherein the sealing bag (1), the front cover (2) and the rear cover (3) are all plastic material. The sealing bag (1) is filled with the liquid balancing matter (4) inside, and plastically sealed under high temperature at both ends. The diameters of the front cover (2) and the rear cover (3) are matched with the inner diameter of a launch barrel (5), and the sealing bag (1) is provided between the front cover (2) and the rear cover (3). In an ordinary transportation state, the liquid balancing matter (4) is well sealed in the sealing bag (1), and a missile is launched forward by the propulsion of powder during launch, the sealing bag (1), the front cover (2) and the rear cover (3) crack instantaneously, and the liquid balancing matter (4) is ejected backward outside the barrel at high speed. The forward and backward impulses are similar or equal, thereby reducing or eliminating the impulse to the launch barrel (5) during launch. The device has a simple structure and uses the pollution-free liquid balancing matter (4), thus there is no pollution after launch.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
