FSB Passive Shuttle-Controlled PSA Devices

摘要

In this paper, the two new FSB passive shuttle-controlled PSA devices are proposed. Compared with the existing PSA device, the principles and action lists of those two new schemes are discussed in detail. In order to explain the principle clearly, the action principles and the functions of the adjustable shuttle-type three-way diffluence valve and the adjustable shuttle-type four-way diffluence valve are presented in turn. As a result, the new schemes have the advantages of less components, higher safety, higher reliability and higher automation.
