| 发明名称 | Brake cylinder maintaining valve | ||
| 摘要 | A system for maintaining brake cylinder pressure comprises a maintaining valve, a brake pipe, an emergency reservoir, and a brake cylinder configured to be in fluid communication with the brake pipe and the emergency reservoir. The brake pipe is configured to sustain a predetermined pressure within the brake cylinder during a brake application based on a differential between a pressure of the emergency reservoir and a pressure of the brake pipe. | ||

| 主权项 | 1. A system for maintaining brake cylinder pressure comprising: a maintaining valve; a brake pipe; an emergency reservoir; a brake cylinder configured to be in fluid communication with the brake pipe and the emergency reservoir; and a minimum application/release protection valve configured to prevent the flow of air from the brake pipe to the brake cylinder until a pressure within the brake cylinder has reached a first predetermined value, wherein the brake pipe is configured to sustain a second predetermined pressure within the brake cylinder during a brake application based on a differential between a pressure of the emergency reservoir and a pressure of the brake pipe, and wherein the minimum application/release protection valve is configured to prevent the flow of air from the brake pipe to the brake cylinder from the maintaining valve during a release of a service brake application. | ||
