本报告的目的是向设计、应用和维护工程师提供有关金属弹簧通电密封装置在飞机流体动力部件（如致动器、阀门和旋转密封套）中用作活塞（OD）和杆（ID）密封时使用的基本信息。定义了弹簧通电密封，并描述了当前使用的基本类型。根据摩擦、泄漏、使用寿命、安装特性和互换性，介绍了根据给定设计要求选择弹簧通电密封类型的指南。弹簧通电密封件也可以制成各种形式和类型，包括端面密封件（内部和外部压力密封类型），以及旋转型密封件。本文将不讨论这些进一步的类型，但许多相同的原则也适用于它们。

The purpose of this report is to provide design, application and maintenance engineers with basic information on the use of metallic Spring Energized sealing devices when used as piston (OD) and rod (ID) seals in aircraft fluid power components such as actuators, valves, and swivel glands.The Spring Energized seal is defined and the basic types in current use are described. Guidelines for selecting the type of Spring Energized seal for a given design requirement are covered in terms of friction, leakage, service life, installation characteristics, and interchangeability.Spring Energized seals can also be made in various forms and types, including face seals (internal and external pressure sealing types), and rotary variants too. These further types will not be discussed in this document, but many of the same principles apply for them as well.
