An anti-compound system for an air brake for a vehicle is provided to simplify a composition of a system, to reduce the number of parts, and to decrease a manufacturing cost by integrating a double check valve with a rear brake relay valve. An anti-compound system for an air brake for a vehicle comprises a rear brake relay valve, and a double check valve(50). The rear brake relay valve is connected with a foot control valve. The double check valve is installed at one side of the rear brake relay valve and connected with a control valve of the parking brake. The rear brake relay valve and the double check valve are connected with the rear air chamber respectively. The double check valve is integrally installed with the rear brake relay valve. The double check valve includes a housing(51), a path(52) formed in the housing, ports(55,56,57), and a piston(53) moved on the path. The path has air pressure discharging holes(54). |
