Abstract
Disclosed is a vehicle compressed air supply device, comprising pressure maintenance valves for service brakes, which are positioned between a junction chamber and compressed air channels for primary brakes; a pressure maintenance valve for the parking brake, which is positioned between the junction chamber and a compressed air channel for the parking brake; and a pressure maintenance valve, positioned on a supply path that connects the pressure maintenance valve for the parking, brake with the junction chamber, and which is closed until the pressure of the compressed air that is supplied to the compressed air channels for the primary brakes reaches a prescribed pressure value. The pressure maintenance valve has the same structure as the pressure maintenance valves for service brakes and the pressure maintenance valve for the parking brake.
