  • Brake health monitoring system
    Patent number: 12036964
    Abstract: A brake health monitoring system and method measure pressures in different components of a brake system of a vehicle system during movement of the vehicle system. Two or more of the pressures that are measured in the different components are compared with each other to select a health monitoring mode. One or more allowable pressures are selected based on the health monitoring mode that is selected. A state of health of the brake system is determined by comparing one or more of the pressures that is measured with the one or more allowable pressures that are selected.
    Type: Grant

  • Graduated release/proportioning valve
    Patent number: 6971723
    Abstract: 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.
