近五年来出现的26-C 型客车制动机,已在部分铁路干线及市郊旅客列车总计316辆车上安装使用。这表示这种新型客车制动机是适合于各铁路使用的。制动机的发展美国铁路协会于二次世界大战后开始研究的一种统一、改进、轻型新式自动空气制动机,在统一性能上能与应用中的制动机混编联运,并能大大降低制动装置的维修费用。为了降低目前使用的滑阀和涨圈勾贝的过高维修费,新方案采用了膜板阀和“O”形圈塞柱阀。根据欧洲铁路使用的统一、改进型空气制动机,制造并采用了 E-3型三通阀。根据这种长行程膜板及“O”形圈运用经验,提出了统一、改进、轻型、基本的26-C 型自动空气制动装置。美国铁路最初称之为26号装置。基于这种装置的运用
The 26-C passenger car brake that has emerged in the past five years has been installed on a total of 316 cars on some of the railway lines and suburban passenger trains. This means that this new passenger car brake is suitable for use on all railroads. Development of the Brake The United States Railway Association began a study of the World War II after a unified, improved, light new automatic air brake, the uniform performance with the application of brakes mixed intermodal, and can greatly Reduce maintenance costs for the brake. In order to reduce the overly high maintenance costs of the currently used spool valve and bellows, the new scheme uses a diaphragm valve and an “O” ring stud valve. Based on the uniform, improved air brake used on the European railway, the E-3 three-way valve was manufactured and used. According to this long stroke diaphragm and “O” ring experience, put forward a unified, improved, light, basic 26-C automatic air brake device. U.S. Rail initially called it a 26th unit. Based on the use of this device
