Abstract
A combination quick release and service relay brake valve assembly is used to consolidate multiple valve functions within a common valve assembly, which reduces cost and overall complexity in an associated vehicle brake system. The combination quick release and service relay brake valve assembly includes a valve body with a quick release portion that has a parking brake port and a service brake control port, which is in fluid communication with an anti-compounding passage. The valve body also includes a service relay portion that has a supply port fluidly connected to a service brake air reservoir and a delivery port fluidly connected to a brake actuator that generates service brake requests.
