Abstract
The present invention provides a gasket for use in a service portion of a brake control valve in a railway braking system. The gasket comprises an elastomeric composition with a predetermined shape. There is a series of bead-like projections formed on the first surface of the gasket for sealing such gasket with a body portion of the valve. A first aperture is disposed in the gasket at a predetermined location for engagement with a projection on the filling piece of the service portion. A brass insert is molded into the elastomeric composition and has a second aperture formed therein. The second aperture is in fluid communication with an auxiliary reservoir of such railway braking system. A third aperture is formed in the gasket in a third predetermined location. A brass insert, which has a first predetermined configuration, is molded into the elastomeric composition of the gasket. The brass insert is disposed in a lower quadrant of the first surface of the gasket and has a fourth aperture disposed therein having a second predetermined configuration. The fourth aperture is in fluid communication with a brake pipe. There are bead like projections formed on the opposed planar second s…
