摘要 |
A release graduating proportioning valve for a rail car brake system having a brake pipe, a brake cylinder, and a load sensor valve. The release graduating proportioning valve has a conventional proportioning piston with a control volume communicating on a first side thereof and a second volume communicating on an opposite side thereof. A graduated release valve member, which can be incorporated into the top of the proportioning valve, is interposed between the control volume and atmosphere for providing a graduated release of brake cylinder pressure via the control volume. The graduated release valve member is activated by movement of the proportioning piston.
