ABSTRACT:
An air brake system for a vehicle includes both automatic braking and direct braking. The equipment for direct braking requires the installation of a main air reservoir pipe in the longitudinal direction of a train. A single pipe serves both as the brake pipe for automatic braking and as the main air reservoir pipe for direct braking. A control valve for automatic braking is connected to the air pipe via a pressure-adjust valve for adjusting the pressure of the air supplied to the control valve to a specified value, and via a check valve arranged parallel thereto. An air pipe supplying the pressure from the control valve to the brake cylinder and an air pipe supplying the pressure from the direct brake equipment to the brake cylinder are respectively connected to the brake cylinder via a double check valve.
