In order to research into more novel and reliable full-hydraulic automatic reversing device for booster and the methods of parameters calculation related to the reversal frequency of booster, on the basis of discussing super high pressure water jet generators, including the working principle of booster, and making an all-round analysis of the automatic reversing devices for all types of boosters at home and abroad, a classification method of existent automatic reversing device for boosters is put forward. This classification method is definite in concept and helpful to specify the design of this-type devices. A full-hydraulic automatic revesing device, which has many advantages such as specific structure, simplified system, lower noise level, less faults, and so on, is proposed. The experiment has shown that the calculation and the new device used in the design of water jet cutting machines have simplified the structure of water jet generators and improved their reliability. It plays a positive and impellent role in improving the quality of super high pressure water jet cutting machines and in the development of water jet cutting technology.
