  • Dual-piston relay valve having an anti-compounding function
    Patent number: 10427663
    Abstract: A relay valve is provided for a vehicle. The valve includes a parking brake piston that is displaceable in a housing and an axially displaceable cuff, a first compressed-air chamber for receiving compressed air from a control line is formed between the parking brake piston and the housing. The valve is also provided with a first spring element, which axially applies a pre-loading force to the cuff, and with a second spring element, which axially applies another pre-loading force to the parking brake piston. An axially displaceable service brake piston is arranged axially between the parking brake piston and the cuff, the service brake piston rests at least radially against the parking brake piston and radially against the housing in a sealing manner, in order to form a second compressed-air chamber.
