摘要： The present invention provides a ball cock for a railway vehicle which comprises a main body possessing a primary-side opening and a secondary-side opening which face one another and an air exhaust aperture which is formed between these openings. Such ball cock further incudes a ball-shaped valve body which is rotatably provided inside such main body and in which there is formed a communication aperture which connects the primary side opening and the secondary-side opening and a side aperture which, consequent to its rotation, connects the air exhaust aperture and either the primary-side or secondary-side opening. There is formed in the main body's air exhaust aperture a pipe connection to which can be connected a restrictor. In another embodiment an extension pipe is connected to such pipe connection in such air exhaust aperture. Such pipe extension forms a bend portion which causes its opening surface to be positioned lower than a generally horizontal direction when, in accordance with the state in which the main body is fitted to a railway vehicle, its air exhaust aperture is positioned upwardly from such horizontal direction.

摘要： A pressure control valve equipped with a solenoid valve, in which a main valve body is provided with an air-supply chamber connected to a pressurized air source, a control pressure chamber into which pilot pressure is input, an output chamber connected to an air-pressure apparatus, and an air-supply valve which establishes contact between and isolates such air-supply chamber and such output chamber. Such pressure control valve further includes a pressure-adjusting piston which is urged one way by a pressure-adjusting spring and is urged the other way by such pilot pressure of such control pressure chamber, and a hollow exhaust valve rod is provided integrally with such pressure-adjusting piston to open or close such air-supply valve in accordance with such pilot pressure; and in which such solenoid valve supplying such pilot pressure to such control pressure chamber is attached to such main valve body. Such pressure control valve is characterized in that such valve body of such solenoid valve is fitted in one of an upper surface and a lower surface of such valve main body, in a position in which it is adjacent to such exhaust valve rod.
