| Abstract: | In this paper, the principle and structures of a flow- regulator used for liquid rocket engines is introduced. The main problems in the development process are introduced in detail. Based on statistic mechanical analysis under the working condition of the regulator, the reasons are analyzed. The improved structures have been put forward and have been tested. The results of tests show that the reliability of the regulator has been improved after structures improvement |
