Brake control valve apparatus |
摘要 |
A fluid operable brake control valve apparatus is provided which includes a brake cylinder valve for controlling the supply of fluid pressure into and out of a brake cylinder. The valve is operable by a main pressure responsive member moveable in response to changes in pressure when applied to a brake pipe. A quick service valve is operable in response to such a change tending to cause a brake application for connecting a quick service volume to the brake pipe to enhance the change at commencement of an application. An accelerated release valve device is operable in response to release of fluid pressure from the quick service volume to connect a charged accelerated release reservoir to the brake pipe to assist a change of pressure in the brake pipe causing such a release.
