Abstract
A valve, for use with a vehicular brake system including an electronic control unit, including a valve body, a pressure regulator internal to the body, a solenoid valve internal to the body and a double-check valve internal to the body. The electronic control unit (ECU) controls the traction control valve during two modes of vehicle operation. The regulator assembly is in fluid communication with the pressurized air supply and regulates the air supplied to the brake system during one mode of operation. The solenoid valve receives pressure-regulated air from the regulator assembly and is controlled by the electronic control unit during the two modes of operation. The single double-check valve receives pressure-regulated air from the solenoid valve and receives pressurized air from the supply, such that the double-check valve allows the pressure-regulated air to flow from the solenoid valve to the brake system during the one mode of operation, and allows the pressurized air to flow from the pressurized air supply to the brake system during the other mode of operation.
